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.

6 Houston entrepreneurs land on coveted Inc. Female Founders 500 list

the future is female

Six Houston female entrepreneurs and innovators were named to the 2026 Female Founders 500 list.

The annual list compiled by Inc. Magazine recognizes female founders based in the U.S. who have built businesses that have moved their industries forward. The group collectively generated approximately $12.3 billion in 2025 revenue and $12.2 billion in funding to date, according to Inc. Five Houstonians were named to the list last year.

"Each year, we are increasingly amazed by the extraordinary leaders on our Inc. Female Founders 500 list," Bonny Ghosh, editorial director at Inc., said in a news release. "The honorees on this year's list include innovators in AI, beauty and wellness trendsetters winning devoted fans, and nonprofit leaders making a real impact in their communities. Together, they're showing all of us what trailblazing female leadership looks like."

The Houston founders are:

  • Sassie Duggleby, CEO and co-founder of Houston space tech and engine company Venus Aerospace. Duggleby also serves on the Texas Space Commission board of directors.
  • Stephanie Murphy, CEO and executive chairman of Aegis Aerospace, which provides space services, spaceflight product development, and engineering services. Murphy also serves as chair of the Texas Aerospace Research and Space Economy Consortium Executive Committee.
  • Laureen Meroueh, CEO and founder of Hertha Metals, which has developed a cost-effective and energy-efficient process that converts low-grade iron ore of any format directly into molten steel or high-purity iron in a single step.
  • LaToshia Norwood, managing partner of L'Renee & Associates (LRA), a full-service project management consulting firm.
  • Lauren Rottet, president and founding principal of Rottet Studio, an international architecture and design firm focused on corporate, lifestyle and hospitality projects
  • Nina Magon, founder and CEO of Nina Magon Studio / Nina Magon Consumer Products, a residential and commercial interior design company. She also co-founded KA Residences earlier this year.

"Grateful to be recognized again on the Inc. Female Founders 500," Duggleby said in a LinkedIn post. "The best part of building Venus Aerospace has been working with an incredible team pushing the boundaries of flight—and helping bring more women into aerospace along the way.

Meroueh, whose company emerged from stealth last year, voiced a similar push for bringing more women into the fold.

"We've seen a 7x jump in female-led IPOs over the last decade, from just two in 2014 (less than 1% of all IPOs) to 14 in 2024 (nearly 9% of all IPOs). Progress is happening," Meroueh shared in a LinkedIn post. "Yet, less than 1% of venture funding in hard tech goes to female-founded companies. But as my friend Ana Kraft says, the right man for the job may be a woman."

Twenty-nine Texas female founders made this list, including Amber Venz Box, founder of the Dallas-based LTK shopping platform, and Cheryl Sew Hoy, CEO and founder of Austin-based Tiny Health, a fast-growing at-home microbiome health platform. See the full list of winners here.

NASA clears Artemis moon rocket for April launch with 4 astronauts

3, 2, 1...

NASA has cleared its moon rocket on for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.

The space agency has only six days at the beginning of April to launch before standing down until April 30 into early May.

"It's a test flight and it is not without risk, but our team and our hardware are ready,” NASA's Lori Glaze told reporters at the end of the two-day flight readiness review.

Glaze and other NASA officials declined to provide the risk probabilities for the upcoming mission.

History has shown that a new rocket has essentially a 50% chance of success, said John Honeycutt, chair of the mission management team.

There's so much gap since the only other SLS flight — more than three years ago without anyone on board — that it's difficult to understand any risk assessment numbers, Honeycutt said.

“It's not the first flight," Glaze said. "But we're also not in a regular cadence. So we definitely have significantly more risk than a flight system that's flying all the time.”

Late last month NASA's new administrator, Jared Isaacman, announced a major overhaul of the Artemis program to speed things up and, by doing so, reduce risk.

Dissatisfied with the slow pace and lengthy gaps between lunar missions, he added an extra practice flight in orbit around Earth for next year. That is now the new Artemis III, with the moon landing by two astronauts shifted to Artemis IV. Isaacman is targeting one and maybe even two lunar landings in 2028.

NASA's Office of Inspector General warned in an audit that the space agency needs to come up with a rescue plan for its lunar crews. Landing near the moon's south pole will be riskier than it was for the Apollo astronauts closer to the equator given the rough polar terrain, according to the report.

The report cited the lunar landers as the top contributor for potential loss of crew during the first few Artemis moon landings. It listed the space agency’s loss-of-crew threshold at 1-in-40 for lunar operations and 1-in-30 for Artemis missions overall.

Contracted by NASA to provide the moon landers for astronauts, Elon Musk's SpaceX and Jeff Bezos' Blue Origin have accelerated work in order to meet the new 2028 target date. The inspector general's office said many technical challenges remain including refueling their landers in orbit around Earth before flying to the moon.

NASA sent 24 astronauts to the moon during Apollo, 12 of whom landed on it. All but one of the moonshots — Apollo 13 — achieved their prime objectives. The program ended with Apollo 17 in 1972.

Kinder leads 19 Houstonians on Forbes' World's Billionaires List 2026

World's Richest 2026

According to Forbes, there has “never been a better time to be a billionaire” than in 2026, and the publication's newest World’s Billionaires List has revealed the 19 Houston billionaires that have risen among the wealthiest worldwide.

Kinder Morgan chairman Richard Kinder surpassed hospitality honcho Tilman Fertitta as the richest billionaire in Houston, ranking No. 232 on the global list with an estimated net worth of $13 billion. His net worth has grown by $2.4 billion since last year.

Fertitta, 68, may not be the richest Houstonian anymore, but his wealth is still on the rise. He ranked 268th on the list with an estimated net worth of $11.7 billion, up from $11.3 billion last year.

Out of the 390 billionaire newbies that made their debut onto the list this year, one of them calls Houston home: restaurateur and commodities trader Ignacio Torras. Torras, 61, is the founder and CEO of global commodities trading company Tricon Energy, and he owns Michelin-starred local restaurant BCN Taste & Tradition and its sister eatery MAD. But that's not all he spends his time doing, according to Forbes.

"In 2024 Torras launched a soccer tournament for neurodivergent players called the Genuine Cup," his profile said. "Last year 800 players and 30 teams from around the world played at Rice University stadium."

Torras debuted as No. 2600 on the list with an estimated net worth of $1.5 billion.

Houston-born multi-hyphenate superstar Beyoncé Knowles-Carter also staked a claim among the world's richest people in 2026. She ranked No. 3332 on the list with a net worth of $1 billion, thanks to her "years of music sales, touring and collecting art with her already-billionaire husband Jay-Z (estimated net worth: $2.8 billion)," Forbes said.

"The majority of pop star Beyonce’s net worth comes from her roughly three decades as a solo performer and a member of the girl-group Destiny's Child," her profile said. "She holds the record for the most Grammy wins ever, with 35, and won her first Album of the Year trophy in 2025. She and her billionaire husband Jay-Z purchased a $200 million Malibu mansion in 2023, in what was the most expensive home sale in California history."

Beyoncé also ranks No. 21 in the publication's separate list of The World's Celebrity Billionaires.

Here's how the rest of Houston's billionaires fared on this year's list:

  • Toyota mega-dealer Dan Friedkin: No. 279; $11.4 billion, up from $7.7 billion
  • Pipeline heir Randa Duncan Williams: tied for No. 323 with an estimated net worth of $10.2 billion, up from $9.3 billion in 2025. Fellow pipeline heirs Dannine Avara and Milane Frantz tied for No. 332 globally. Each has an estimated net worth of $10.1 billion, up from $9.2 billion. Scott Duncan ranks No. 353 with a $9.8 billion estimated net worth, up from $9 billion in 2025.
  • Oil tycoon Jeffery Hildebrand: No. 341; $10 billion, up from $7.7 billion
  • Houston Texans owner Janice McNair and family: No. 528; $7.3 billion, up from $6.2 billion
  • Energy exploration chief exec George Bishop of The Woodlands: No. 908; $4.7 billion, down from $5 billion
  • Westlake Corporation co-owners Albert Chao, James Chao and their families: tied for No. 1074; $4 billion, flat from 2025
  • Hedge fund honcho John Arnold: No. 1504; $2.8 billion, down from $2.9 billion
  • Perry Homes executive chair Kathy Britton: No. 1611; $2.6 billion, flat from 2025
  • Houston Astros owner Jim Crane: No. 1676; $2.5 billion, up from $2.4 billion
  • Former Houston Rockets owner Leslie Alexander: No. 1834; $2.3 billion, up from $1.9 billion
  • Mercedes-Benz mega-dealer Joe Agresti: No. 3185; $1.1 billion, flat from 2025
  • Frontier Airlines chairman William Franke: No. 3332; $1 billion, down from $1.2 billion

Elsewhere in Texas

Austin billionaire Elon Musk was declared the world's richest person for the second consecutive year, and Forbes said his “grip on the top spot is as strong as it’s ever been.”

“Musk became the first person to hit $500 billion in wealth, in October,” Forbes said. “Then $600 billion and $700 billion, within four days in December. Then $800 billion, in February.”

The Tesla, SpaceX, and xAI founder’s current net worth has skyrocketed to $839 billion — a shocking $497 billion more than his 2025 net worth.

In Dallas-Fort Worth, Walmart heiress Alice Walton has maintained her elite status as the world’s richest woman for the third year in a row. Walton is the 14th richest person on the planet with a current net worth of $134 billion, an eye-catching $33 billion higher than her 2025 net worth. She is the first American woman worth $100 billion, and one of only 20 “centi-billionaires” worldwide claiming 12-figure fortunes, also known as the "$100 Billion Club."

Koch Inc. stakeholder Elaine Marshall and her family are the richest Dallas residents, ranking No. 71 globally with an estimated net worth of $30.9 billion. Her net worth has grown by $2.6 billion since last year.
