A Houston venture capital firm has announce big news of its latest fund.

Mercury, founded in 2005 to invest in startups not based in major tech hubs on either coast, closed its latest fund, Mercury Fund V, at an oversubscribed amount of $160 million. Originally expected to raise $150 million, Fund V is the largest fund Mercury has raised to date.

“We are pleased by the substantial support we received for Fund V from both new and existing investors and thank them for placing their confidence in Mercury,” Blair Garrou, co-founder and managing director of Mercury Fund, says in a news release. “Their support is testament to the strength of our team, proven investment strategy, and the compelling opportunities for innovation that exist in cities across America.”

The fund's limited partners include new and existing investors, including endowments at universities, foundations, and family offices. Mercury reports that several of these LPs are based in the central region of the United States where Mercury invests. California law firm Gunderson Dettmer was the fund formation counsel for Mercury.

Fresh closed, Fund V has already made investments in several companies, including:

  • Houston-based RepeatMD, a patient engagement and fintech platform for medical professionals with non-insurance reimbursed services and products
  • Houston and Cheyenne Wyoming-based financial infrastructure tech platform Brassica, which raised its $8 million seed round in April
  • Polco, a Madison, Wisconsin-based polling platform for local governments, school districts, law enforcement, and state agencies
  • Chicago-based MSPbots, a AI-powered process automation platform for small and mid-sized managed service providers

Mercury's investment model is described as "operationally-focused," and the firm works to provide its portfolio companies with the resources needed to grow rapidly and sustainably. Since 2013, the fund has contributed to creating more than $9 billion of enterprise value across its portfolio of over 50 companies.

“Over the past few years there has been a tremendous migration of talent, wealth and know-how to non-coastal venture markets and this surge of economic activity has further accelerated the creation of extraordinary new companies and technology," says Garrou. "As the first venture capital firm to have recognized the attractiveness of these incredible regions a dozen years ago, we are excited to continue sourcing new opportunities to back founders and help these cities continue to grow and thrive.”

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from corporate innovation to fintech — recently making headlines in Houston innovation.


Youngro Lee, founder of Brassica

Brassica Technologies, a fintech infrastructure company that's providing a platform for alternative assets, is just the next step in his career in using tech to democratize finance. The idea came from Lee's experience as a startup founder and fintech exec — first at NextSeed and then at Republic, which acquired NextSeed two years ago.

"The reason why I thought this was what I wanted to focus on next was exactly because it was an issue I struggled with as a founder of NextSeed," Lee says on the show. "The backend was always an issue. There's not one single vendor that we felt really understood our business, was doing it efficiently, or enabled us to deliver those services to our end clients."

Lee shares more about the future of Brassica, including the challenges he's facing within regulation and the state of fintech as a whole, on the podcast. He also weighs in on how he's seen the Houston innovation ecosystem grow and develop alongside his own entrepreneurial journey. Read more.

In 2021, KPMG, a New York-based global audit, accounting, and advisory service provider, formed a new entity to play in the innovation space. The Houston-based team finds innovative software that benefit KPMG's clients across industries.

In an interview with InnovationMap, Anu Puvvada, leader of KPMG Studio, shares more about the program, its first spin out, and why she's passionate about leading this initiative from Houston.

"When you think about innovation as a whole, it's mired with risk and uncertainty," she says. "You never know if something's going to work or not. And part of what we have to do with any idea that we're building in the studio or anything that our clients are doing around innovation, we have to do as much as we can to mitigate that risk and uncertainty. And that's kind of what KPMG's wheelhouse is." Read more.

Brock Murphy, Parent ProTech co-founder

Houston-based Parent ProTech is a one-stop shop for parental education on technology and applications that their kids use.

“Our goal is to make everyone the best digital parent possible,” Brock Murphy, Parent ProTech co-founder, tells InnovationMap. “We understand technology and the role it plays in influencing the next generation. So we help parents when it comes to understanding the platforms, how to use them and how to unlock the parental controls that can be hidden, deeper into these platforms.”

Murphy — with co-founder Drew Wooten and creative director Joshua Adams — launched the platform in September 2022. Since then, Parent ProTech has made its mark through partnerships with schools in Texas. Read more.

Houston entrepreneur furthers mission of democratizing finance with latest venture

HOUSTON INNOVATORS PODCAST EPISODE 186

After seeing through an exit of his first startup NextSeed, lawyer-turned-entrepreneur Youngro Lee took on a leadership role at the acquiring company, Republic. But his fintech innovation wheels kept turning.

"Brassica is, I personally consider, an extension and a national evolution of my original starting point," Lee says on the Houston Innovators Podcast, "which is basically to democratize finance so that everyone can have access to alternative assets as part of their wealth management investments or even for pleasure to just be able to invest in things they believe in."

Brassica Technologies Inc. is a fintech infrastructure company that's providing a platform for alternative assets, Lee explains. While investments in the public markets have platforms already, there are other investment opportunities that are managed in a less optimized way for investors.

Lee says there hasn't been a seamless solution created for the backend of these transactions, things like custody of those assets or transferring and keeping track of them.

"The reason why I thought this was what I wanted to focus on next was exactly because it was an issue I struggled with as a founder of NextSeed," Lee says on the show. "The backend was always an issue. There's not one single vendor that we felt really understood our business, was doing it efficiently, or enabled us to deliver those services to our end clients."

Lee says he has been working on addressing this gap in the market for the past two years under his role at Republic. After holding an executive position at the company as a whole, he currently oversees the Asian market as general partner of Republic Asia.

"We didn't know where this process was going to go. It was a corporate initiative to try to understand what the market needs — because we needed it," Lee says. "We quickly realized that this idea can be really big. Once we had that conclusion, that the problem we're trying to solve and the opportunity that the market presents is significant enough, we knew Brassica deserves to be its own company."

Shortly after that, Lee started reaching out to potential investors and raised an $8 million seed round to take the company out of stealth last month. Houston-based Mercury Fund led the round, with participation from Valor Equity Partners, Long Journey Ventures, NGC Fund, Neowiz, Broadhaven Ventures, Armyn Capital, VC3DAO, Alpha Asset Management (Korea), and other global FinTech investors participated in the round.

Lee shares more about the future of Brassica, including the challenges he's facing within regulation and the state of fintech as a whole, on the podcast. He also weighs in on how he's seen the Houston innovation ecosystem grow and develop alongside his own entrepreneurial journey.

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.”
