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.

Report: Houston reclaims top 10 ranking among America's best cities

Houston has made a triumphant return to America's 10 best cities for 2026, certifying the city is a cornerstone of the country's growth and economic prosperity.

Houston ranks No. 9 nationwide in the annual "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy. Each year, the report ranks the relative qualities of livability, cultural "lovability," and economic prosperity in 393 American cities with metropolitan populations of 500,000 or more.

Dallas surpassed H-Town as the No. 8 best city in America, and the Lone Star State boasts a strong presence among the top 25. Austin and San Antonio, respectively, were named the 11th and 24th best American cities this year.

Previously, Houston was dubbed the 13th best American city in 2025, down from its No. 10 ranking in the 2024 report.

Rather than profiling each individual city like in past reports, the 2026 edition focuses on regional and state prosperity. Texas' economic dominance is second only to Florida's, and the state's growth is solidified by the Dallas-Houston-Austin "triangle," where each metro has its own distinct economic identity, but when combined "form one of the most formidable regional economies in the world."

"In our 2026 survey, Dallas ranks third nationally as the place Americans believe offers the best job opportunities, Austin fifth, and Houston seventh," the report's author wrote. "That concentration of perceived economic opportunity in a single state is unmatched, and the GDP data confirms it isn’t just perception."

After being named one of the best places to start a business or a career earlier in 2026, Houston has continued to punch above its weight with its success in tourism, education, and housing growth.

Overall, the report found a correlation between a city's population growth and its latest ranking, with bigger cities appearing higher up on the list. The top three best American cities — New York, Los Angeles, and Chicago — are coincidentally the three largest metros, while Dallas and Houston are the fourth and fifth largest but appear eighth and ninth on the list.

"Scale compounds at the large city level — more people generate more economic activity, more cultural infrastructure, more employer presence, which attracts more people," the report said.

The top 10 best cities in America for 2026 are:

  • No. 1 – New York
  • No. 2 – Los Angeles
  • No. 3 – Chicago
  • No. 4 – Miami
  • No. 5 – San Francisco
  • No. 6 – Seattle
  • No. 7 – Las Vegas
  • No. 8 – Dallas
  • No. 9 – Houston
  • No. 10 – Boston

New probe into Tesla after vehicle slams into Houston-area home at high speed

Tesla Talk

The top U.S. auto regulator opened an investigation Monday, June 22, after a Tesla using an automated driving feature slammed into a Texas home at high speed and killed a 76-year-old woman standing inside.

The National Highway Traffic Safety Administration said it's opening a special investigation into the Tesla Model 3 crash on Friday near Houston, a significant probe because the car was using technology that Elon Musk considers key to the company's future.

The Tesla CEO is rolling out robotaxis using automated software in several U.S. cities this year and plans to invite Tesla owners to put their cars into the fleet using the same system across the country.

The driver told the Harris County Sheriff's Office that he was using the technology, according to a police report on the crash, but it's not clear what role, if any, it played in the incident.

Tesla did not respond to a request for comment but the head of the company's artificial intelligence efforts suggested on social media later Monday that the self-driving feature was not to blame.

“In this case, the driver manually overrode self-driving by pressing the accelerator all the way to 100% of the accel pedal in this residential area,” wrote Ashok Elluswamy on X, the platform that is now part of Musk's rocket company, SpaceX. “They reached a speed of 73 mph during the crash, and had the accelerator pressed even after the crash.”

The police report noted that the driver was not drunk and is cooperating. It identified the woman killed as Martha Avila.

Video obtained by KHOU-TV shows the car traveling at top speed over the front lawn of a brick home in Katy, then ramming into a front room. The next shot shows the car encased in the home amid piles of crumbling plaster, split beams and bits of furniture.

The auto safety regulator, known as NHTSA, has launched several investigations into Tesla, including one late last year into 58 incidents in which Teslas reportedly violated traffic safety laws while using self-driving technology, leading to more than a dozen crashes and fires and nearly two dozen injuries.

A few months earlier, the NHTSA opened an investigation into why Tesla apparently had not been reporting crashes promptly as required.

As for special crash investigations, the NHTSA has opened 46 involving Teslas using self-driving or driver-assistance technology over the past decade, according to the agency's records. In more than a dozen of those crashes, at least one person — a driver, passenger or pedestrian — was killed.

Tesla stock fell sharply early last year as car sales plunged amid a boycott of Musk after he waded into politics, leading President Donald Trump's budget-cutting Department of Government Efficiency initiative and embracing European extremist candidates.

Musk has since shifted the Tesla story to one less about car sales and more about AI and robotaxis, and done so successfully. The stock is up 16% in the past year.

Intuitive Machines lands $1M grant to expand robotics operations

Expansion mode

Houston-based Intuitive Machines is expanding its operations around the country.

The space tech company—which has offices and labs in Texas, California, Arizona, Colorado and Maryland—announced that it has received a $1 million grant from Maryland Gov. Wes Moore through the state's Build Our Future Grant. The funding will go toward expanding Intuitive Machines’ Super Cislunar Robotics Assembly Building (Supa-CRAB) Mechanisms and Robotics Center of Excellence in Anne Arundel County.

The company will move into a 69,000-square-foot facility and build out additional lab and office space. It will also procure equipment that will allow for in-house Assembly, Integration and Test (AI&T) activities, according to a news release. Intuitive Machines says the expansion will take place this fall.

“This collaboration shows how industry, state programs, and education can reinforce one another,” Steve Altemus, CEO of Intuitive Machines, said in the release. “Maryland invests in innovation, companies grow and hire, students gain experience, and communities benefit from new opportunities and long-term career pathways. Together with Governor Moore, the state of Maryland, and Anne Arundel County leaders, we are building a permanent path to long-term lunar operations, an advanced robotics and mechanisms center of excellence, and a technology edge for our nation.”

Intuitive Machines first launched operations in Maryland in 2021 and has since expanded five times in the state. The company officially opened its robotics and mechanisms facility in 2024.

The Maryland team has built robotics and mechanisms for the Nova-C landers and IM-1 and IM-2 missions. In the future, Intuitive Machines expects the Maryland team to work on its IM-3 Rover Deployment Mechanism (RDM), a 360 pan-tilt camera for panoramic views, the Main Engine Gimbal (MEG), and the company's first data relay satellite, known as Altus-1.

Intuitive Machines moved into a new $40 million headquarters at the Houston Spaceport in 2023. The company announced an expansion of its lease last year.

The company announced a $175 million equity investment to fuel growth in March. It's since landed a $180 million NASA CLPS award to deliver seven payloads to the moon's Mons Malapert on the IM-5 mission.
