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."

5 Houston-area companies named among world's most innovative for 2026

In The Spotlight

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned praise on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.

UH lands $11.8M for first-of-its-kind early language development study

speech funding

Researchers at the University of Houston have secured an $11.8 million grant from the National Institutes of Health to conduct a first-of-its-kind study of early language development.

Led by Elena Grigorenko, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Psychology, and research professor Jack Fletcher, the study will follow 3,600 children aged 18 to 24 months to uncover how language skills develop at this critical stage and why some children experience delays that can influence later growth.

The NIH funding will also support the development of the new national Clinical Research Center on Developmental Language Disorders at UH, which aims to bring experts from psychology, education, health and measurement sciences to study how children learn language.

“This will be the first national study to estimate how common late talking is using a large, representative sample of Houston toddlers,” Grigorenko said in a news release. “By following these children as they grow, we hope to better understand the developmental pathways that can lead to conditions such as developmental language disorder and autism.”

UH’s team will partner with the pediatric clinic network at Texas Children’s Hospital, where children will be screened for early language development, allowing researchers to identify those who show signs of delayed speech. Next, researchers will follow the cohort through early childhood to examine how language abilities evolve and how early delays may lead to later challenges.

The Clinical Research Center on Developmental Language Disorders will be the 14th national research center established at UH, and will include researchers from multiple UH departments, as well as partners at Baylor College of Medicine and the Texas Center for Learning Disorders.

“This level of investment from the National Institutes of Health reflects the significance of this work to address a complex challenge affecting children, families and communities,” Claudia Neuhauser, vice president for research at UH, said in a news release. “By bringing together experts from multiple disciplines and partnering with major health systems across the region, the project reflects our commitment to advancing discoveries that impact our community.”

Rice Alliance names Houston healthtech exec as first head of platform

new hire

The Rice Alliance for Technology and Entrepreneurship has named its first head of platform.

Houston entrepreneur Laura Neder stepped into the newly created role last month, according to an email from Rice Alliance. Neder will focus on building and growing Houston’s Venture Advantage Platform.

The emerging platform, which is being promoted by Rice Alliance and the Ion, aims to connect founders with the "people, capital and expertise they need to scale."

"I’ve spent a lot of time thinking about what it takes to make an innovation ecosystem more navigable, more connected, and more useful for founders," Neder said in a LinkedIn post. "I’m grateful for the opportunity to do that work at Rice Alliance, alongside a team with a long history of supporting entrepreneurship and innovation."

"Houston has the talent, institutions, and industry base to create real advantage for founders," she added. "I’m looking forward to listening, learning, and building stronger pathways across the ecosystem."

Neder most recently served as CEO of Houston-based Careset, where she helped bring the Medicare data startup to commercialization. Prior to that, Neder served as COO of Houston-based telemedicine startup 2nd.MD, which was acquired for $460 million by Accolade in 2021.

"Laura brings a rare combination of founder empathy, operational experience and ecosystem leadership," Rice Alliance shared.

Neder and Rice Alliance also shared that the organization is hiring developers to design the new Venture Advantage Platform. Learn more here.
