Josh Feinberg hates security deposits. It's a sum of money sitting in an account, not earning interest and not doing either the landlord or the tenant any good.

That's why Feinberg and his co-founder, Marissa Limsiaco, created Otso. The duo previously founded Tenavox, an online portal for commercial real estate listings for brokers to generate leads, and have now launched this fintech platform that provides landlords with an alternative to cash security deposits.

Feinberg teamed up with Euler Hermes, a 135-year-old credit insurance company, to create Otso, and the credit company backs the lease performance of each tenant that is approved by Otso. The transaction calls for a fee added to the rent, but no large cash deposit would be required.

Both landlords and tenants can apply for Otso, and the process can be done with a new lease or an addendum for existing leases — something that Feinberg sees as an opportunity considering the financial burden COVID-19 has put on startups and small businesses.

Feinberg tells the Houston Innovators Podcast that, while he originally envisioned Otso to be a new deal product for landlords to offer an alternative to cash deposits, he saw the tool as an opportunity for small businesses struggling to pay rent that have a shortage of liquidity. He tossed out the original marketing plans and pivoted to present Otso as that liquidity solution for small business tenants.

"The cool thing about having a startup is that, unlike a big business, you can be really nimble," Feinberg says in the episode.

The COVID-19-caused crisis has rocked the commercial real estate industry. On a recent call with around 30 brokers, Feinberg says none of them had made a deal in the past month.

"This is the first time I've ever seen the entire market basically grind to a halt," he says.

On the episode, Feinberg shares some advice for startups worried about their relationship with their landlords. He stresses how important communication and tapping into resources available online like Otso, which has a slew of info online.

"Real estate is a team sport," Feinberg says. "You need these advisers now more than ever — talk to your landlord and your broker."

There's no doubt for Feinberg that the country is going to recover, and the biggest question marks are regarding timeline. Ultimately, innovative companies will pull through and might even be better for the challenges overcame.

"Great companies are built during crises — that's been true for a very long time," "There are smart people working on big problems no matter what the economy or outside markets are doing. And when they are able to survive periods like this, they come out significantly stronger than their competitors and weaker or outdated concepts."

Feinberg joins the Houston Innovators Podcast to discuss Otso, advice for startups keeping lean, and where the government's next round of relief should go to. Listen to the full episode below — or wherever you get your podcasts — and subscribe for weekly episodes.

Houston small businesses and landlords grapple with rent relief options during COVID-19 crisis

late fee

It's not too huge of an assumption to make that many Houston startups and small businesses failed to pay their rents in full yesterday. Since the city's stay-at-home mandate on March 24 — and even preceding that — most businesses have seen a slowdown of revenue as a result of COVID-19-caused business disruptions.

Business owners are frantically looking in their leases and searching online to see what rights they have and what sort of protection they have in such an unprecedented time.

"People are confused. They don't know what to do, and finding information is hard," says Meredith Wheeler, co-founder and chief creative officer of Sesh Coworking, which opened earlier this year.

Wheeler and Sesh's co-founder, Maggie Segrich, have created a petition to get on the radar of local elected officials to challenge them to pass legislation to protect small businesses in this time.

"At the end of the day, it would be so wonderful and idealistic to say that we could rely on the niceties and the moral compasses of our landlords, but it's probably not true for everyone and so that's why we need legislation to dictate what is right," Wheeler says.

But landlords are also in unchartered territory, says Josh Feinberg, who has worked in Houston as a commercial real estate broker and co-founded CRE tech platform, Tenavox.

"There's this idea that there's this acrimony between tenant and landlord, and I think, as a former broker, we're set up that way to get our side the best deal. But in reality, that's just not true," Feinberg says. "The majority of commercial real estate is owned by regular people — not usually some faceless, gigantic corporation."

And they have a piper to pay too, Feinberg adds. Ninety percent of CRE is owned by debt, he says. If the government steps in anywhere, it should be on the lender level, as well as creating some sort of tax relief.

"If there's any relief here, it's going to have to come from lenders, and I think you'd hear that from owners and brokers," Feinberg says.

In somewhat convenient timing, Tenavox has recently co-founded a new company that provides a bit of a solution for small businesses. Otso provides landlords with an alternative to cash security deposits. Traditionally, deposits are held onto by landlords — they aren't legally allowed to spend it unless the tenant defaults.

"In general, I think cash deposits are wasteful," Feinberg says. "It's critical capital that the business can hire with, invest, and use."

Tenavox teamed up with Euler Hermes, a 135-year-old credit insurance company, to create Otso, and the credit company backs the lease performance of each tenant that is approved by Otso. The transaction calls for a fee added to the rent, but no large cash deposit would be required.

The tool can be used on new leases, and, in light of the current situation, Otso can also be used to create an addendum in existing leases so that the tenant can get back their deposit and use it in this time of crisis. Either landlord or tenant can apply online and hear back that same day — Feinberg says he's focused on a speedy response to help get this deposit money back to the tenant.

"If we can get some liquidity back into the hands of the business, they have some a better chance of survival," Feinberg says.

Other than looking into Otso, Feinberg has some other recommendations for small business owners. He says they should be applying for relief from the Small Business Administration, which has more money to dole out than they have ever had. And, as it pertains to working with their landlords, communication is key. Show financials and specific information — like what March 2019 looks like compared to 2020 — so that landlords can take that to their lenders.

"An unprecedented crisis is going to require unprecedented solutions," Feinberg says.

When you're in great need for a therapist, the worst thing you have to do go through the process to actually find someone you can count on. It's a tiring process to discover a new therapist who meshes well with you and has the capabilities for what you need. Ryan Schwartz created Mental Health Match to pair up patient to professional — and it's designed to be free for those who need it most: The patient. Check out the story here.

Tenavox leader on expanding in Texas and LGBTQ representation within innovation

Featured innovator

After founding her second startup, Marissa Limsiaco thought that would be her last.

But years later, Limsiaco, a U.S. Army veteran with three degrees under her belt, was pulled back into the entrepreneurship world by Tenavox, a commercial real estate leasing company that gives tenants negotiating power through an online platform that shares space requirements, location and an expected price for the unit.

This month, InnovationMap is profiling the faces of Pride within Houston innovation. Limsiaco spoke with InnovationMap about her career, Tenavox, and the importance of the LGBTQ community in entrepreneurship.

InnovationMap: What has happened with Tenavox in the last eight months since InnovationMap has spoken with you?

Marissa Limsiaco: Oh gosh, it has felt like years. In the startup world, eight months is like two years and three months is like a year it feels. (Back in November), we were just launching our sales efforts.

Since last year going into this year, our (monthly recurring revenue) has grown over 100 percent. We've now connected tenants to agents and generated over $3.5 million in deals. So that's been really exciting that we're making those connections. And now most recently, we've closed a round this month. We are kind of focusing on a new offering called Tour Ready that we're selling to customers are on the project leasing side. Ultimately, it allows people who are looking for space to see and book a tour in a matter of minutes if it feeds their needs.

IM: I know that you took your service in the military and used that experience with leadership and management to become a successful entrepreneur. You have been a part of different startups in addition to Tenavox. Could you have imagined yourself at this point in your career 5 to 10 years ago?

ML: Absolutely not. I would not have even thought this was an option 5 or 6 years ago. Even though I was out of the Army, I was still learning business and going through that transition. After that second business that I started I told myself "I'm never going to do this again," and now I'm on my fourth.

IM: What compelled you to keep going in the startup world?

ML: It was this opportunity and the impact that we can have on everybody that we're helping on this platform, from business owners all the way to commercial agents and ownership groups. As a business owner myself, I experience the struggle firsthand of finding space and how frustrating that was. And it's sad that in 2019, one of the most effective ways to find spaces is driving around, calling signs with little to no information. When I saw how big the problem was and how antiquated the industry is where nothing has changed as far as making it any better for people to search for space to lease, I was just super determined to solve this problem.

IM: The last time InnovationMap spoke to you, Tenavox had just received funding from RealCo, an accelerator program funded by Geekdom fund. What has that funding been used for?

ML: Oh, yeah, we've raised more funding since then. And we have enough money now to go to the rest of Texas, which is exciting.

IM: When are the expansions?

ML: Well right now, we're in Houston and Austin and then we're going to go to Dallas towards the end of this year. We are also going to raise a round to go out of Texas. Josh [Feinberg, my co-founder,] and I have a larger vision vision for Tenavox and we really want to take it national. So we're going to prepare toward the end of this year, and next year we're going to open up on a bigger round of fundraising to be able to go to other states.

IM: What are some of the ways the tech and innovation community support their LGBTQ colleagues throughout the month of June?

ML: Expanding to other industries and awareness of minorities in other industries, whether it be LGBTQ or women, I think highlighting folks that are in those groups that are in the industry helps a lot. Two years ago when I became CEO and we started this company, it was daunting and scary. There's not a lot of women doing what I do, right? Something that keeps me going is that I have to show another girl or whoever that it's possible to be in my position.

IM: What advice would you have for a young gay or lesbian entrepreneur heading into the military or tech and real estate industries?

ML: Don't be scared to do things that you're scared of. I know everybody's different but the times I found myself in positions like I am today was because I was scared of it. I was scared of what happened, but I knew that I had to do it to overcome it or to see what would happen. The last industry in this whole entire world ever that I would have thought about five years ago would be commercial real estate. And yet when the opportunity presented itself, I just went for it. I just knew that I was going to grow and because I challenged myself and whenever I've faced that, I've come out totally another person, especially just me personally in this role. I tell a lot of the young people that I mentor that if an opportunity presents itself and it may not interest you, you should still look into because you just never know.

IM: What does Pride Month mean to you?

ML: It means empowering the LGBTQ community. The importance of having a whole month in this year that is dedicated to reminding everybody — and it even extends beyond LGBTQ — that you should just be who you are. Be proud of who you are. And I think that means a lot.

3 Houston innovators to know this week

Who's who

Entrepreneurs see a problem, and solve it. This week's three innovators to know are no different. All three have personal stories of realizing there's something not right — and there's something they could do about it.

Here are this week's innovators with small businesses and big growth plans.

Yared Akalou, founder of Alcove Group

Yared Akalou found the perfect job for himself — only problem was that it was in San Diego. Uninterested in moving his wife and young daughter across the country, he decided to prove to his new employer that he could handle most of the job's responsibilities remotely, while traveling when needed.

It wasn't easy, and his user experience-focused mind realized there was a concentration problem when you worked remotely in public spaces. Now, with Alcove, he's created a solution. Alcove is a laptop case that pops up into a workspace that increases focus and privacy.

Alcove is available online, but Akalou has lofty goals of partnering with large companies to get Alcove in the hands of consultants, for instance.

Megan Eddings, founder of Accel Lifestyle

Entrepreneurs have to have a certain amount of positivity when it comes to all the challenges they face, and Megan Eddings has a surplus of both challenges and positivity. She's fought for years to design the perfect fabric that doesn't hold on to bacteria and sweat smells for a line of athleticwear she's creating. The chemist-turned-medical sales professional is now close to getting her company, Accel Lifestyle, off the ground.

When she's not focusing on Accel, she likes to inspire others to follow their passions and take a leap of faith like she did at speaking engagements or on social media. She even inspired her husband, Kyle, to start something of his own too.

Josh Feinberg, co-founder of Tenavox

For years, Josh Feinberg was a broker focusing on The Woodlands when he realized there was a huge need in the commercial real estate sector that brokers weren't able to fill. The equation was just off — there just aren't enough brokers to manage the millions of available square feet of space in major metros.

Feinberg created Tenavox with his business partner, Marissa Limsiaco, who is based in Austin. Tenavox is a website where small business owners can find space that fits their needs. Tenavox can benefits both sides of the transaction: entrepreneurs are only shown compatable properties and brokers are only getting tenant leads that are serious contenders.

The site also has VoxLink, which is a directory of industry experts — tenant brokers, moving companies, lawyers, etc. Feinberg hopes to expand to 50 metros in the next five years.

Real estate startup makes it easier for Houston small businesses to find space

Whether you're looking for a home, a hair stylist, or an electrician, you're probably going online to find it. A Texas startup is trying to make finding retail or office space for small businesses just as easy and accessible.

Traditionally, businesses hire a broker to find applicable commercial real estate property to rent. But Josh Feinberg, a former broker with J. Beard Real Estate Co., says small business owners are more frequently beginning the search process online themselves — to no avail, since there really isn't any resources out there for tenants.

"We're the only tenant-focused platform," Feinberg says. "Commercial real estate isn't like residential where there's 100 websites that can show people homes to buy or apartments to rent."

He's worked over the past few years with his business partner, Marissa Limsiaco, to create Tenavox, an online referring platform where small business owners can search and find properties that fit their budgets, space requirements, and location.

"We're in a time where people don't want to waste time to be matched or linked to things they need, whether it be food coming to your door or a car picking you up to go somewhere," Limsiaco says. "Tenavox almost like a dating platform, where business owners tell us what their needs are in a space, vendors tell us who their ideal client or tenant is, and Tenavox matches them efficiently."

Tenavox currently has over 120 million square feet of rentable, searchable property in Houston and Austin. The company launched in Houston originally, where both the founders are from and where Feinberg is based, before moving into the Austin market, where Limsiaco now lives. It's free for users — just sign in with your email address and begin your search. You get only results that fit your specifications, and Tenavox only gets a kick back when a deal is made. The startup also recently picked up funding from RealCo, an accelerator program funded by Geekdom Fund.

Brokers stand to benefit from Tenavox as well. It's cheap for retail or office brokers to list their properties — $25 a year per property — and brokers only get potential leads that fit the profile of the property. For instance, if a small business owner is looking for a retail space in the Galleria area, they will only be matched with properties in the Galleria area that fit their budget.

"Brokers' sole job is to generate transactions," Feinberg says. "Tenavox is the only targeted marketing solution that is qualified lead generation for commercial brokers."

But that's just the start for the company that launched in March. Now that the infrastructure and data is set in place, Feinberg says they will expand to all the major Texas cities by next year and in over 50 markets nationwide in the next five years. Feinberg says they are targeting metros in private-record states, where traditionally there's more power on the landlord side of transactions.

Tenavox is also expanding its features for users. VoxLink is a search engine option within Tenavox where users can find reputable brokers, lawyers, moving companies, or other service providers.

"We're not just a listing site," Feinberg says. "We're a comprehensive resource."

Generation Park lands new facility to scale xeno-organ production

Organ innovation

Maryland-based United Therapeutics Corp. has opened a new 77,448-square-foot facility to manufacture xeno-organs in Northeast Houston’s growing biotech hub, Generation Park.

The new Houston location is United Therapeutics’ third Designated Pathogen-Free (DPF) site, named for transplant pioneers Dr. Bartley P. Griffith and Dr. Robert A. Montgomery. The company says the new facility will enable it to scale commercial production of its xeno-organs once they receive regulatory approval.

An existing DPF facility in Virginia is supporting clinical trials for the xeno-organs, and a third site in Minnesota will also focus on commercialization with the Houston site, according to the company.

Xeno-organs are organs taken from a non-human animal source and transplanted, implanted or infused into a human recipient.

Currently, United Therapeutics is advancing clinical trials to support a Biologics License Application with the U.S. Food and Drug Administration for its investigational-stage xenotransplantation, UKidney, UThymoKidney and UHeart products. The products all involve working with the genes from humans and pigs.

In 2025, Chron.com reported the company was working to construct an estimated $96 million facility to breed genetically engineered animals. Head of investor relations at United Therapeutics Dewey Steadman told the Houston Business Journal in 2025 that the pigs’ DNA will be edited. In November 2024, a 53-year-old woman in Alabama received a transplanted kidney from UKidney that had 10 gene edits. She had the transplant removed in April 2025, after her body rejected it.

The Dr. Bartley P. Griffith and Dr. Robert A. Montgomery Xenograft Production Facility requires a “strictly controlled, biosecure barrier environment, including air filtration, filtered water, filtered feed supplies, and state-of-the-art decontamination entryways,” according to the company. Being pathogen-free means it includes calibrated air and water conduits to support the transplantability of xenograft products and to prevent contamination. For energy considerations, the building also features solar arrays.

“With our third xenograft production facility now open and clinical trials underway, United Therapeutics is moving closer to its goal of providing transplantable organs to the people who need them,” Martine Rothblatt, chairperson and CEO of United Therapeutics, said in a news release. “It is fitting that this facility is named for Dr. Griffith and Dr. Montgomery, whose first-in-human surgeries turned xenotransplantation from a theoretical possibility into a clinical reality.”

The facility, which wrapped construction in August, is located at 11848 Common Dock Dr. in Generation Park, which will house manufacturing sites for pharmaceutical heavyweights Bristol Myers Squibb and Eli Lilly. Last fall, Eli Lilly tapped Generation Park for its $6.5 billion manufacturing plant, and Bristol Myers Squibb made a $2.3 billion investment in August to bring its state-of-the-art site to the master-planned commercial district.

Elon Musk's SpaceX reports profit as AI and satellite businesses booms

Booming Business

SpaceX reported a bigger quarterly profit than expected on Tuesday, October 20, as its satellite communications and artificial intelligence businesses boomed.

The company, run by Elon Musk, posted a profit for the three months through September 2026 of $4.4 billion, or 35 cents per share, reversing a year-ago loss and easily topping Wall Street's expectations. Revenue soared to $14.6 billion, up 161%.

On a conference call with analysts, Musk suggested a merger with his electric car company Tesla might be in the works, something that has been rumored for months. He said both companies formed “special committees” of independent directors to discuss the issue, though he played down the chances of an imminent deal.

“Some people out there assume that a SpaceX and Tesla merger is a certainty,” he said. “I think that would be overstating it.”

The AI business became SpaceX's largest by revenue in the third quarter, although the Starlink satellite service remains the biggest profit generator.

“They beat across all metrics and the Starlink business looks to be accelerating,” said Dan Ives, an analyst at Yorkville Ives. “This is just what (Wall) Street wanted.”

The stock rose 7.5% in after-hours trading.

Musk also told analysts that for next month's launch of its Starship rocket, SpaceX will attempt to grab both the booster and ship with mechanical arms upon return to base, a key step toward demonstrating it can reuse the massive spacecraft.

“The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle,” Musk said, calling the attempt, if successful, “a massive technology milestone.”

SpaceX hopes to get Starship on a regular launch pattern in preparation for NASA's upcoming lunar missions.

The company already has huge contracts with the federal government, and House Democrats have called for investigations into those contracts and Musk’s work with the Department of Government Efficiency. Musk has spent $276 million since July in support of Republican candidates.

In a filing for its initial public offering in June, SpaceX warned that a change in control of Congress could have a “material and adverse impact on our growth and competitive position.”

Musk recently drew criticism from politicians in Washington after speeds for a military version of SpaceX's satellite communications service were slowed for Ukraine following President Donald Trump's deal to get more diesel oil from Russia amid a push to end the war. The Wall Street Journal reported Tuesday that it was Musk who ordered the slowdown, impeding Ukraine’s use of drones along the front. SpaceX did not immediately respond to an Associated Press request for comment on the Journal story.

Both Trump and Musk have denied responsibility for the slowdown.

As midterm elections near, Musk on Monday promised to give one share of SpaceX to “every kid in America” next year, though he provided no details on how the distribution would be carried out. With communities nationwide protesting the construction of large data centers and concerns about AI safety, AI companies are trying to build goodwill. Anthropic pledged to commit 5% of its shares to a new “public benefit” fund.

SpaceX shares have been under pressure over concerns that the company was spending too much on major projects to compete with rivals such as Anthropic. The company said capital expenditures totaled $19.6 billion last quarter, nearly triple the figure from a year earlier, and it forecast spending would grow to $35 billion to $40 billion in the current quarter.

Shares of SpaceX closed Tuesday at $147.79, down from a peak near $201 after its IPO, which made Musk the world’s first trillionaire at the time. But the share prices for SpaceX and Tesla have since dropped, reducing his net worth to $925 billion, according to Forbes magazine.

Tesla reports third-quarter financial results Wednesday. Last week, Tesla unveiled a new Roadster sports car that in some versions may include thrusters allowing it to briefly fly using SpaceX technology — though experts say anything usable for drivers is a long shot.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.
