Earlier this year, Houston-based serial entrepreneur Larry Lawson celebrated the exit of his medical device company, Preventice Solutions, which he sold to Boston ScientificBoston Scientific in a $1.4 billion deal.

Nowadays, Lawson is laser focused on investing in the Houston innovation ecosystem, particularly in medical device, as well as working on Proxima Clinical Research, a contract research organization in the Texas Medical Center he co-founded with Kevin Coker.

Lawson joined InnovationMap for a Q&A about the exit, his role on the boards of five med device companies, and his investment activity. He also shares how he sees the impact of COVID-19 and where Houston's burgeoning innovation ecosystem is headed.

InnovationMap: Earlier this year you saw an exit for your company Preventice Solutions, a company focused on the development of mobile health solutions and remote monitoring, which was sold to Boston Scientific in a $1.4 billion deal. What did this deal mean to both you and the company?

Larry Lawson: It validated what I started back in 2004. I had an idea, And I moved forward on my idea — in the beginning completely financed that idea myself. I tried to raise funds, and it was very difficult here in Houston back in 2004 to do that. I put my money, you might say, where my mouth was and I started the company and funded it and built it to a point to where we attracted some venture capital from one of the world's largest VC groups out of California called Sequoia Capital. That allowed me to really increase our exposure and our footprint nationally. And it just grew and grew and eventually Boston scientific got interested in the company, along with Merck, a pharmaceutical company, and they bought smaller pieces of the company.

Then at the end of the year of 2020, Boston Scientific made a play to acquire the company completely. Frankly, it have been better. I would have never dreamt that my original company would be worth that much and sell for that much. So it was very nice for not only me, but for many other people that were employed by Preventice, because as a founder of the company, I knew how important it was to share equity with the people that really make the company run and make it run well.

IM: I noticed that you’re on the board of several Houston health tech startups — most of which I’ve covered on InnovationMap. What do you look for in a company before joining the board and what role do you play for the companies’ growth?

LL: First of all, I look at the people who are in the company — from top level executive level all the way down, even including the existing board members of the company. I only invest in medical device companies. That's what I know, and that's why I've spent over 50 years in, and I feel like I know it very well. I do not venture far off of that line or that path at all.

I look for a strong operating group. I look for strong leadership — and if I can bring even stronger leadership and have them get from point A to point B, I like to get involved. Given my medical as the chairman of the company.

IM: You started your investment firm in 2018 — what inspired you to create LAWALA Capital and what do you look for in potential portfolio companies?

LL: I really limit my investments to the medical device segment of health care. LAWALA is just me — it's the first two letters of all three of my names: Larry Wayne Lawson. How I got into investing and starting companies is I see opportunity, and I see voids in the industry.

IM: Speaking of, you founded Proxima Clinical Research in 2017, which has a very hands-on approach to accelerating health tech innovation. Why did you decide to start that up?

LL: I saw a void in the clinical research industry, specifically at the medical center here, the largest medical center on the face of the earth. And it was doing all of this attracting all of these companies, all of these health science companies into Houston, and they were building and budding their companies, but there was no centralized clinical research company to be there for them.

I thought, "my gosh, somebody ought to do this." Well, I'm a doer. So, I went to the powers to be at the medical center and got their approval to be the founder of a company, called Proxima Clinical Research, and the key is putting it right there in the heart of the largest medical center in the world.

It's been really, really good for these companies who are coming into Houston to take advantage of the life science growth that's taking place here in Houston.

IM: How did COVID-19 affect the work that you do?

LL: COVID really did not affect our business that greatly. It affected the investments that I was doing. I pulled back and cut my, expenses and that, because I just needed to see, you know, how the COVID thing would shake out. I'm watching my investments a lot closer today, and think that it's affected the startup companies, more because to be a startup company, you have to go out and find investors to invest in your company. And I think that process has been slowed, I won't say considerably, but I think it's been slowed quite a bit over the past year and a half.

It just so happens that in the industry that I've been in, which is patient monitoring — cardiac arrhythmia monitoring — COVID has heightened patient monitoring more than anything else. What we learned from COVID is that we've got to be more in tune ourselves than ever before in monitoring all aspects of ourselves. What has come out of this COVID pandemic is telemedicine, which has struggled for years, now all of a sudden telemedicine is on the tip of everyone's tongue.

And I think that's one reason why you see the big companies — the multinational, multi-billion dollar companies — getting more in patient monitoring.

IM: Houston is home to the largest medical center in the world — but it’s often times not listed as a top city for medical innovation. Is that changing? And if so, how?

LL: When the medical center purchased the old Nabisco building and turned that into a technology center and a startup center, it changed the whole complexion of the device and medical startup community here in Houston. We've had a lot of former development here through MD Anderson in oncology, but we'd never had very much in devices. Now, we have companies coming from Europe and Asia coming to Houston to promote their technology and the devices that they have built.

The Rice Business Plan Competition is the largest in the United States. We fund more startup companies out of RBPC. I'm talking Harvard, MIT, Stanford, Berkeley — Houston is number one. And that has a lot to do with what has happened in the medical center over the past seven or eight years.

IM: What more do we need, now that we've come this far to really push us into that innovative healthcare city status?

LL: Well, I think what we need is for investors investing in healthcare and not oil and dirt. For years and years, the whole economy was driven by oil and gas and real estate. And I can remember starting my first company, the early eighties, I went to banks to borrow money to start my first company, and all I wanted was $200,000. Well, that was still a lot of money back then, but they would literally fall asleep on me because they couldn't understand and didn't understand exactly what I wanted to do. And so I wound up having to fund myself use my friends and family as investors, but that's changed quite a bit. The health science community here in Houston is now known all over the world. It's gonna just continue to grow and develop, and I hope to be a part of continue to be a part of it.

Houston-based, fast-growing software-as-a-service company, Liongard, closed its $17 million round in May round in May. It was led by Updata Partners with contribution by TDF Ventures, Integr8d Capital, and private investors. With customers in 20 countries, Liongard saw triple-digit customer growth and doubled its staff over the past 18 months, according to a news release.

Liongard's CEO, Joe Alapat, who co-founded the company with COO Vincent Tran in 2015, says that the new funds will continue to support its Roar platform — a software product that creates a single dashboard for all data systems and allows automation of managed service providers, or MSPs, for auditing and security within a company's IT.

"Since the launch of Liongard, the platform's adoption and popularity with MSPs has grown rapidly, transforming Liongard into a highly recognized brand in the MSP ecosystem," Alapat says in the release. "This new investment and the continued confidence of our investors will fuel our growth by giving us the means to further advance our solution's capabilities and serve our customers at an even better level."

Liongard's total funding now sits at over $20 million. Last year, the company raised a $4.5 million series A round following a $1.3 million seed round in 2018. TDF Ventures and Integr8d Capital have previously invested in the company.

Lead investor, Updata Partners, is based in Washington D.C. and invests in SaaS, tech-enabled service providers, and digital media and e-commerce. The HX Venture Fund, a fund-of-funds under Houston Exponential, has invested in Updata Partner's recent fund.

Ambyint's $15M series B

In February, Ambyint, which has an office in Houston, closed its $15 million series B funding round with support from local investors. Houston-based Cottonwood Venture Partners led the round, and Houston-based Mercury Fund also contributed — as did Ambyint's management team, according to a news release. The money will be used to grow both its Houston and Calgary, Alberta, offices and expand its suite of software solutions for wells and artificial lift systems.

"This funding round is an important milestone for Ambyint, and we're pleased to benefit from unwavering support among our investors to boost Ambyint to its next phase of growth," says Alex Robart, CEO of Ambyint, in the news release. "It is also a proof point for our approach of combining advanced physics and artificial intelligence, deployed on a scalable software infrastructure, to deliver 10 to 20 percent margin gains in a market where meaningful improvements have been hard to achieve."

Ambyint's technology pairs artificial intelligence with advanced physics and subject matter expertise to automate processes on across all well types and artificial lift systems.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
