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.

Houston company wins AHA competition for pediatric heart valve design

winner, winner

Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

EO Houston is where ambitious founders go to scale smarter

Don't Go It Alone

Scaling a business from early traction into true growth is one of the most exciting — and punishing — chapters of entrepreneurship. Houston founders know this better than most. Our city is built on ambition: fast-moving industries, talent from around the world, and opportunities that expand as large as the Texas sky.

But as many entrepreneurs eventually learn, scaling isn’t simply “more of what worked.” It requires new systems, new thinking, and often, a new version of the founder. Even the most capable founders eventually face decisions, pressures, and turning points that only other entrepreneurs can truly understand.

Entrepreneurs’ Organization, a global peer-to-peer network of more than 18,000 business owners across 220 chapters in 75+ countries, exists for exactly this stage. One of the largest chapters in the organization, EO Houston brings that global community to life locally, offering founders the connection, learning, and accountability needed to grow sustainably and to grow up as leaders.

A community where founders learn at the highest level
The real value of EO emerges in the lived experiences of other entrepreneurs. When Houston-area founders talk about the moments growth nearly broke their companies, a universal theme appears: you can’t do it alone.

EO Houston member Robert De Los Santos of Sky High Party Rentals learned this the hard way when rapid post-COVID growth made expansion feel limitless — until it wasn’t.

“After COVID, we doubled every year and assumed inventory was the limit. In 2023 we overbought, only to realize demand had peaked. That taught us a hard truth: growth in one city has ceilings. Expanding into Austin and Dallas — the Texas Triangle — gave us new markets to put our inventory to work while we figured out how to penetrate Houston better. The challenge shifted from a strategy of ‘buy more units for demand’ to learning how to tackle the challenges of ‘leading across cities.’”

Founders often enter EO exhausted from trying to maintain control as things grow more complex. Many discover, like Jarred King of Summit Firms, that scaling requires the difficult shift from doing everything to building the team that can.

“We grew quickly because of my network, relationships, and hustle… but I was doing all the work,” King says. “I realized at that point you have to delegate — not just busy work, but important decisions to your key team, as well as set up really effective SOPs.”

“The uncomfortable truth is that you are no longer the best person for most jobs in your company," agrees Darren Randle of Houston Tents & Events. "Your inability to delegate or hire people smarter than you in key leadership and management level roles will become the single biggest drag on the entire business. You have to accept that your original 'hustle' is now a scalability risk."

Making hard decisions, such as walking away from customers or contracts, can feel like less of a sting when you know others have also been faced with tough choices. Aaron Gillaspie of West U's My Salon Suite recalls, “You can’t be everything to everyone, it’s ok to say no, and just understand some customers aren’t the right fit. It’s a two way street and both must win.”

Perspective is perhaps the most important reality check that members find at EO.

“Bigger volume will not make problems go away — you just got to get used to walking the tightrope," says Roger Pombrol of Emerald Standard. "Develop a system for good balance and do not freak out. Scared is no way to live your life. It’s ok if you fall. Your family will still love you. Money is just money. Love is love. The world tries to make you conflate them, but don’t."

Actionable insights from entrepreneurs who’ve already scaled
Conversations like these are happening every month inside EO Forum Meeting. Each EO chapter is divided into several small Forums. These confidential, committed group of 7–10 entrepreneurs who meet to share the real five percent of what they’re experiencing. It’s not advice, but experience — shared candidly, respectfully, and with the kind of vulnerability that leads to breakthroughs.

What makes Forum so impactful is the honesty it draws out. Entrepreneurs are often surrounded by employees, partners, and even family members who rely on them for answers, but seldom do they have a group where vulnerability is not only welcomed, but expected.

Learning experiences that match your ambition
EO supports that growth far beyond peer groups. Through the organization’s global partnerships with institutions like Harvard, Oxford, and INSEAD, Houston members gain access to executive-level learning experiences designed specifically for entrepreneurs.

These programs help founders step out of the day-to-day and think strategically about competitive advantage, innovation, and organizational leadership. Paired with ongoing learning through EO Jumpstart, Nano Learning, and its global library of member-created content, founders stay informed, challenged, and ahead of emerging trends.

And through global communities — ranging from EO Women and EO Under 35 to industry-specific groups — Houston members tap into expertise that spans continents and sectors. Whether someone is navigating M&A, exploring international expansion, or integrating new technologies, the right perspectives are always within reach.

What truly distinguishes EO Houston, however, is its culture. Houston’s entrepreneurial landscape is uniquely diverse and resilient, filled with founders who are hungry to build, innovate, and elevate the city’s business community. EO Houston amplifies that spirit, creating relationships that are as supportive as they are strategic. Many members describe the chapter not simply as a network, but as a catalyst for becoming better leaders, better thinkers, and — just as importantly — better human beings.

Your next level starts here
For entrepreneurs who are ready to scale—beyond their first million, beyond their current comfort zone, and toward a future that requires sharper leadership and stronger community—EO Houston offers an unmatched platform. It is a place where ambitious founders grow faster, think bigger, and gain the confidence to take bold next steps.

If you’re ready to elevate your business and your leadership alongside people who understand the journey, EO Houston is ready to welcome you. Your next level starts with the peers who can help you reach it. Learn more and become a member here.

3 Houston companies land on Deloitte’s Technology Fast 500 list

trending up

Three Houston companies have made this year’s Deloitte North America Technology Fast 500 list.

The report ranks the fastest-growing technology, media, telecommunications, life sciences, fintech, and energy tech companies in North America. The Houston companies to make the list, along with their revenue growth rates from 2021-2024, include:

  • No. 16 Action1 Corp., a provider of cybersecurity software. Growth rate: 7,265 percent
  • No. 92 Cart.com, a commerce and logistics platform. Growth rate: 1,053 percent
  • No. 312 Tellihealth, a remote health care platform. Growth rate: 244 percent

“Houston’s unique blend of entrepreneurial energy and innovation continues to strengthen the local business community, and I’m thrilled to see Houston companies honored on the 2025 Deloitte Technology Fast 500 list. Congratulations to all the winners,” said Melinda Yee, managing partner in Deloitte’s Houston office.

Action1 is no stranger to lists like the Deloitte Technology Fast 500. For instance, the company ranked first among software companies and 29th overall on this year’s Inc. 5000, a list of the country’s fastest-growing private companies. Its growth rate from 2021 to 2024 reached 7,188 percent.

Mike Walters, president and co-founder of Action1, said in August that the Inc. 5000 achievement “reflects the dedication of Action1’s global team, who continue to execute against an ambitious vision: a world where cyberattacks exploiting vulnerabilities are entirely prevented across all types of devices, operating systems, and applications.”

Atlanta-based Impericus, operator of an AI-powered platform that connects health care providers with pharmaceutical and life sciences companies, topped the Deloitte list with a 2021-24 growth rate of 29,738 percent.

“Our mission is to set the standard for ethical AI-powered physician connections to pharma resources, accelerating and expanding patient access to needed treatments,” said Dr. Osama Hashmi, a dermatologist who’s co-founder and CEO of Impiricus. “As we continue to innovate quickly, we remain committed to building ethical bridges across this vital ecosystem.”
