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.

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.

Axiom Space expands executive team with two C-suite hires

new leaders

Fresh off officially making Texas its legal headquarters, Axiom Space has named two new C-level executives.

The Houston-based spacetech company, which is developing the first commercial space station, announced earlier this month that it had appointed Zach Gitomer as its new chief financial officer and Erick Wegerer as chief information officer.

Gitomer served as vice president of investor relations and capital markets for Axiom from March to June of this year. Before joining Axiom, he held various leadership roles at Bank of America, Merrill Lynch, and Citi, where he supported technology and growth companies, according to Axiom.

"Building era-defining space infrastructure and pioneering the orbital economy is a complex endeavor that requires not just an audacious vision and stellar engineering talent, but the financial infrastructure, discipline, and capital strategy to match," Gitomer shared in a LinkedIn post. "I’m honored to take on this role ... I’m looking forward to partnering with the exceptional leadership team here at Axiom Space during a defining chapter for the company and commercial spaceflight broadly, as well as a crucial period for maintaining U.S. human presence in low-Earth orbit and leadership in space exploration."

Wegerer joins Axiom after most recently serving as CIO of Washington-based Insitu Inc., a subsidiary of Boeing that develops customized unmanned hardware for commercial, government and defense customers.

"My time at Insitu was defined by talented people, meaningful challenges, and work that mattered. I'm grateful for the teams, partners, and leaders who made progress there possible. Stepping into Axiom, I'm energized by the mission, the momentum, and the opportunity to help shape what's next," Wegerer shared.

The duo was celebrated on the floor of the New York Stock Exchange last week.

“We are pleased to welcome these exceptional leaders to the Axiom Space team," Axiom CEO Jonathan Cirtain added in the announcement. “Their strong record of helping complex organizations advance their strategic priorities will strengthen our executive team to further advance our core business objectives."

It's been a busy summer for Axiom. The company tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million, in June.

It also announced plans to open a Japanese subsidiary July 1. It tapped veteran Japanese astronaut Koichi Wakata to lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. It also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

Axiom also officially redomiciled its legal headquarters from Delaware to Texas last month. Read more here.

Houston hardtech accelerator names 8 founders to 2026 cohort

hardtech fellows

Hardtech-focused organization Activate has named 50 new members to its 2026 cohort of scientists, which includes eight startups joining Activate Houston.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. Its fellows receive a living stipend, research and development funding, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

This year's fellows represent 41 companies from 22 U.S. cities and 11 states.

“This cohort clearly demonstrates that the next industry-defining companies won't choose between modern technology and deep science; they'll be built by combining both,” Cyrus Wadia, CEO of Activate, said in the announcement. “These are the scientists and engineers turning our most urgent global challenges into the companies that will deliver a more sustainable future.”

The Houston fellows are working across the energy, space, AI infrastructure and agriculture sectors. They include:

  • Sophie Clare Broun, founder of Anning Corporation, which is producing clean hydrogen by stimulating naturally occurring geologic deposits
  • Kathy Andersen, founder of Brint Tech, which builds optical sensing systems that quantify hydrogen for infrastructure operators
  • Dorsa Talebi, founder of Kinetiq Drive, which builds rare-earth-free, contact-free electric motors with wireless rotors for small appliances and heavy industry alike
  • Neethu Pottackal, founder of Nivera, which is developing natural, edible coatings made from agricultural byproducts to reduce food waste and extend the shelf life of fresh food
  • Jonathan Huffman, founder of Orbital Arc, which is shrinking spacecraft propulsion to a microchip powerful enough for deep space
  • Tim Lee, founder of Renesin, which develops advanced materials for faster, more efficient AI hardware
  • Joshua Livingston, founder of Selerra Separations, which is developing high-performance membranes that cut the cost and energy consumption of water treatment
  • Wenli Jiang, founder of SwieNitro Recovery, which is developing technology that converts nitrogen-rich waste streams into valuable fertilizer

"Home to the largest concentration of engineers in the United States and a dense ecosystem of Fortune 100 and Fortune 500 companies, Houston is uniquely positioned for scientists tackling large-scale industrial challenges. Activate Houston fellows are connected to the city's deep networks in energy, chemicals, and materials," Activate said in the announcement.

Activate named its inaugural Houston cohort in 2024. It has other hubs in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Nationally, it has supported 346 fellows and 276 companies since 2015.

Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion. The latest cohort is Activate Houston's third. Read more about the last year's cohort here.

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.
