After Blinds.com successfully exited to Home Depot, founder Jay Steinfeld started thinking about what he wanted to do next. The entrepreneur is now on the boards of five companies and has taught at Rice University before publishing his new book, "Lead From The Core."

"The book was originally written so that the people at Blinds.com would know what got us to where we were and would use it as the foundation for continuing what that success was all about. As I began teaching and expanding my influence throughout the community nationally, I realized that there were many entrepreneurs who could learn from the same success, the techniques, the strategies," Steinfeld says.

Houston Exponential has made another new hire. Clemmie Pierce Martin has joined Houston Exponential as director of marketing and strategy. The nonprofit helps spur the growth of Houston’s innovation ecosystem.

She most recently was director of strategic partnerships and products at Houston-based startup Goodfair, which operates an online thrift store. Before that, she was head of client success at Austin-based startup Mesa Cloud, which offers a platform for tracking student progress.

Martin, who grew up in Houston and graduated from the University of Texas at Austin and Houston’s The Kinkaid School, says her new employer “sees the potential in Houston and our startup ecosystem that I’ve always felt was underserved and underrepresented nationally. I couldn’t be more excited to join a team that is working tirelessly to make sure that for founders and startups anywhere in the world, Houston is not just a choice but rather the clear choice of venue.” Click here to read more.

Voyager Portal, a software-as-a-service platform, closed an $8.4 million series A investment round this week. The round was led by Phaze Ventures, a VC fund based in the Middle East, and included new investors — ScOp Venture Capital, Waybury Capital and Flexport. Additionally, all of Voyager's existing investors contributed to this round.

“Voyager Portal was created to significantly reduce cost, risk, and complexity when transporting bulk materials around the world,” says Matthew Costello, CEO and co-founder of Voyager, in the release. “The last two years have demonstrated just how critical shipping bulk commodities is to global markets – freight rates have increased and port congestion is at an all-time high – accelerating the demand for Voyager’s solution.” Click here to read more.

Q&A: Houston entrepreneur discusses big exits, startup advice, and his new book

Featured Innovator

Jay Steinfeld is a household name — at least within Houston's growing innovation ecosystem. Steinfeld founded Blinds.com and, along with his team, grew it to a $100 million company before exiting to Home Depot in 2014. Over the past few years, Steinfeld has had time to reflect on that empire he created and recount his lessons learned in a new book.

Lead From The Core published this week, and Steinfeld took some time to answer some questions about the new book for InnovationMap. He also shares some insight into the acquisition process and advice for fellow entrepreneurs.

InnovationMap: You founded Blinds.com and exited the company to Home Depot — this is lauded as one of Houston’s big exits. What did this acquisition mean to you as a Houstonian?

Jay Steinfeld: Blinds.com ended up being far greater than what I ever believed was possible. I had no vision as to what it could become. I had no vision as to even what the internet was at the time I started. I knew nothing when I started — I didn't even know you could sell things online. So it's kind of a shock in one way, because we just started as an experiment and not to get rich or to build something massive. It was a marketing experiment and that was all, it was, we had no business plan. We didn't know what the total addressable market was. I didn't even know what a TAM was at the time. It was just an incremental step to improve my drapery shop. So now that we have developed that into by far the number one online retailer of blinds in the world and acquired by Home Depot, it's just so satisfying and so gratifying to know that all the little things that we did with all the people who were so, so much a part of it — like Daniel Cotlar, Tom Cabanski, Larry Hack, Steve Riddell, Marilyn Franks, all these people who, I mean, no one knew who we were. We were nobodies, but we were able to do something and become better than what even we believed was possible.

And that's actually the greatest thing for me — that so many people elevated themselves and either were a part of the success and felt like they were consequential in developing something that was consequential. They were a significant part of that, but they evolved along with it. And are either now still with the company prospering flourishing or they're now with other companies doing the same thing. Omair with Cart.com — starting as an accounts payable cost accountant and working his way up. And now, you know, the story there. It's amazing. So I think the fact that we were able to build these teams and do something of consequence and have people feel really good. It's not about how much money we made, but how much we really impacted ourselves and how we helped each other. And that was the key. We, we brought humanity into the workforce and show that having a culture of people first really does work. And it's not just a bunch of talk.

IM: I think when you look at some kind of growing and successful innovation ecosystems, they start with a couple companies that made it big, created a legacy and a group of successful entrepreneurs that then inspire others. Do you see Blinds.com kind of within the Houston innovation ecosystem?

JS: But I never, at the time, believed that was the case because we were within ourselves and didn't really see a responsibility or anything other than to what our own mission was. Looking back now and seeing how many people have succeeded and how other companies have used our success and even been able to get funded and to bring attention to Houston as a place where big exits can happen. That's a good feeling, but at the time I didn't really reflect on that.

IM: Your book came out this week — what did you want to accomplish with Lead From The Core?

JS: The book was originally written so that the people at Blinds.com would know what got us to where we were and would use it as the foundation for continuing what that success was all about. As I began teaching and expanding my influence throughout the community nationally, I realized that there were many entrepreneurs who could learn from the same success, the techniques, the strategies, "The Four Es" that were really the, the secret sauce of the company, the reason we were able to beat Amazon, Home Depot, and Lowe's, and why we got so much money as a result of it. I then expanded even more because people were saying, you know, I don't necessarily want to start a business, but I want, I've got an entrepreneurial bug and I want it to apply to my career. And for those people who feel stagnant and wanting to grow, these principles apply not just to a business, but to life into career trajectories. And that's been particularly satisfying because it was always about helping people become better than what they believed possible, not about the mission of Blinds.com itself. That was the mission, helping people. And now that people are re it's resonating outside the business world to any type of career, that's pretty cool. And now I realize that the audience is much broader than what my original intention was.

IM: What’s the biggest thing you want readers to take away from the book?

JS: I think if he can do it, I can do it. I think that's really it. It's not as hard as people think. I mean, it is tedious and you have to stay immensely focused, but it's a simple process. If you don't get so static in your thinking, and you're more expansive and open to possibilities — possibilities of you changing of you improving, and you're improving everybody around you — and that if you have the time and a little bit of money, then you can incrementally improve enough and fast enough that you can build something of significance too.

IM: What did you wish you had known before starting the process? 

JS: I actually wish I hadn't known any of this beforehand, or I might not have started. It's it is intensely grueling. It's not just the writing process, which in itself is hard — and the editing process, the rewrites, and the different types of editors that we've been involved with publisher — it's just the business of a book. It's it's everything. It's getting a publisher, getting editors, determining artwork for the cover and for the interior artwork, the publicity for the book who narrates it the whole process of audiobooks and rights. It's like starting a company. If you knew how hard it was going to be, you've might not have started it from the first place. So, but that's one of the things that was great about and be starting a business. I had no idea what I was doing, and I knew as much about writing a book, as I knew about starting a business. And that gave me an advantage because I didn't have bad habits. I didn't have a predetermined understanding as to what had to be in order for this to work. I would just meander through experimenting, being curious, asking for a lot of help, helping having people express themselves so I could get diverse opinions — like I did making business decisions. And that's what I want people to get from the book — that they can make these little decisions. And if it doesn't work, you stop. If it does work, you do a lot more of it. And that's what I did with the book. It's been fun. It's exactly what my "Four Es" are — experimenting, evolving, expressing, and enjoying myself.

IM: That's so meta that working on the book was like the process of what you're writing about in the book. Could you see yourself doing it again?

JS: Yeah, I've got two other book ideas — one will be a lot easier because it's not about me. It's harder to write about yourself, but writing about something else will be a lot easier. And now that I know the process, it will be so much easier. The first time is always harder. Going back to what you said about "it's kind of meta," if your core values are something, then that means that's what you do. So it shouldn't be surprising to anybody that I am experimenting and evolving and expressing and enjoying, because those are absolutely true, authentic core values for me. And therefore that means that's how I behave all the time. That's what I do every day. Not as a goal or an aspirational idea — if people can understand what is absolutely true to them and not just who they want to be, I think they'll be able to do almost anything they want.

IM: You’re involved with several companies and even have taught at Rice University. What drove you to get involved in this endeavors?

JS: Well, I'm either on board or advisory board members of five different companies, and it's a diversified group because some are in the pre-A stage and one's a public board. When I was about to step away from blinds.com, the idea was how do I keep having an active role in helping companies, but not be so active that I'm up to my eyeballs every day with the primary responsibility. I've got two in Austin, one in Chicago, one here, and then the other one's in Tampa.

The first thing I wanted to do knowing that I was going to be leaving Blinds.com was to start teaching in Houston, and this was while I was writing the book. So, it gave me an opportunity to bounce off ideas in the classes while writing and seeing what would be good to put into the book. It was like comedians going to small markets first and testing their material. That was fun, and I found that the things that I was teaching them was outside the normal courses that they were taking. I was providing that more personal introspective view while they were learning all the true skills, like evaluating markets, discounted cash flow and things like that. And that was very exciting for me to be involved there, especially with such a prestigious school like Rice. Al Donto was the one who I teach with, and he's been a great mentor and a great facilitator of that process.

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.
