The second quarter of 2023 looked a lot like the first when it came to venture capital funding for Houston companies. The whole country — affected by inflation, geopolitical instability, and other factors — has seen a trying time for investment opportunities.

Houston's performance is far from unique. Globally, VC funding is down — a reported 18 percent from Q1 to Q2, per Crunchbase. Year over year, that's a 49 percent decrease from 2022's Q2.

According to InnovationMap reporting, 10 Houston-based, Houston-founded, or soon-to-be Houston-headquartered companies announced VC or grant funding between April and June. Here's a roundup of these second quarter deals — click on each story to read more.

For the second time in just over a year, a Houston business that provides mobile commerce and digital marketing to the mobility and fuel industries has raised $40 million.

P97 Networks, which has developed a cloud-based mobile commerce platform that helps brands securely do business with customers, announced that it has closed its series C round at $40 million. The equity financing round was led by Portage and included participation from existing investors. The fresh funding will go to support growth strategy.

"In this highly connected world, retail brands are looking for new ways to increase consumer engagement — the power of network effects in the digital world will be a key contributor to revenue growth and margins," says Donald Frieden, CEO of P97 Networks, in a news release. "With consumers of all ages further adopting mobile payment solutions, we are proud to have built the leading connected commerce and digital marketing platform for the convenience retail, energy marketing, and transportation industry."

A Houston startup that combines unique sensor technology with software analysis has raised its next round of funding to — according to Founder and CEO Josh Teekell — turbocharge its sales.

SmartAC.com launched in 2020, emerging from stealth with $10 million raised in a series A. Over the past almost three years, the company has firmed up its hardware, developed its software, and pivoted slightly from selling directly to consumers to adopting a B2B approach.

Now, Teekell says he's focused on turbocharging sales to these contractors, and he's going to do that with the funding raised in the series B round that closed this month. He says the company will also grow its team that goes out to deploy the technology and train the contractors on the platform.

"This funding really buys us a couple years of runway through the end of next year and allows us to focus on getting to cash flow breakeven, which is right around our wheelhouse of our abilities here in the next 12 months," Teekell says. "In general, we've accomplished everything we'd be able to accomplish on the hardware side, and now it's just about deployment."

The $22 million SmartAC.com has raised came from local investors. Teekell, who hasn't announced the full list of the round's investors, explains that while traditionally startups might have more opportunity on the coasts for raising money, it's not hard to sell Houstonians on the benefits of SmartAC.com's optimized air conditioning.

Between Bangalore and Chennai in the Indian state of Andhra Pradesh, you’ll find the town of Tirupati. It’s home to seven peaks that host a Hindu temple complex devoted to a form of Vishnu, Venkateshvara. It is also the region from which Upendra Marathi originally hails. It’s where his father, and many other family members, attended medical school.

“My father’s first job was to take care of the pilgrims,” recalls Marathi.

It's only natural that his groundbreaking Houston company would be named 7 Hills Pharma.

“That sort of selflessness and giving back, I wanted to embody it in the name of the company,” Marathi says.

Now, 7 Hills Pharma is announcing that last month, it was awarded a $13.5 million grant from the Cancer Prevention and Research Institute of Texas (CPRIT). That’s on top of more than $13 million in NIH grants, making the company the second largest recipient of SBIR/STTR grants in Texas. Continue reading.

A biotech company has landed a more than $13 million grant from the Cancer Prevention and Research Institute of Texas.

The nearly $13.3 million grant given to OncoResponse — which is relocating from Seattle to Houston, according to CPRIT's news release — will help the company develop fully human monoclonal antibodies for treatment of cancer that otherwise would not respond to immunotherapy. OncoResponse already has a partnership with MD Anderson Cancer Center, which is one of the company’s investors.

“We are thrilled to receive this recognition from CPRIT in supporting the potential of our immunotherapy candidate OR502. We greatly appreciate the additional support from our investors as we continue to make significant progress with our drug development efforts advancing immunotherapies derived from clues of Elite Responders,” says Clifford Stocks, CEO of OncoResponse, in a news release.

They say it’s all in the timing. For CellChorus, it’s all in the TIMING. That’s Time-lapse Imaging Microscopy In Nanowell Grids. TIMING is a visual AI program that evaluates cell activation, killing and movement, which allows scientists to better understand how cells function.

The technology is important to the development of novel therapies in the realms of oncology, infectious diseases, and countless other disorders and diseases. By allowing scientists to observe those maladies at their roots, it will enable them to create, and ultimately deliver new medications and other therapies faster, at lower cost, and with a higher success rate.

CellChorus is a spinoff of the Single Cell Lab at the University of Houston. Part of UH’s Technology Bridge, CEO Daniel Meyer connected with co-founder and leader of Single Cell Lab, Navin Varadarajan, through co-founder Laurence Cooper.

“The company had been established, but there were limited operations,” recalls Meyer during a phone call with InnovationMap.

That was the fall of 2020. Now, the team has just announced a $2.3 million SBIR (Small Business Innovation Research) Fast-Track grant from the National Institute of General Medical Sciences. Continue reading.

A health tech startup that just collected $1.7 million in pre-seed funding aims to eventually plant its headquarters in Houston.

The startup, Rosarium Health, currently has no headquarters; its 10 employees work remotely from various locations. However, co-founder and CEO Cameron Carter — who lives in the Denver area — says the company is eyeing a future headquarters in Houston.

“We believe Houston is the best city to launch a health care startup, given the Texas Medical Center, diverse talent across health and technology, affordable living, and a city with supportive and progressive communities,” Carter tells InnovationMap. “We feel Houston offers meaningful attributes that can enable a high-growth startup to succeed and for its employees to feel safe.” Continue reading.

A Houston-based company that's developing an engine that'll enable one-hour global transportation has announced its latest investor.

Venus Aerospace released the news that Silicon Valley venture capital firm, Airbus Ventures, has joined its team of investors. The supersonic combustion engine technology — more akin to a rocket's engine than an airplane's — is revolutionary because allows for travel at a higher elevation. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally.

“Venus has developed the world’s first liquid-propellant rotating detonation rocket engine (RDRE) with a double-digit percentage increase in efficiency over standard regular engines, making the hypersonic economy possible,” says Sassie Duggleby, CEO and co-founder of Venus, in a news release. “We’re delighted to bring Airbus Ventures into the Venus family and look forward to growing our collaboration as we harness the future of hypersonic flight.” Continue reading.

Seattle biotech co. to move to Houston thanks to $13.3M grant from Texas organization

CPRIT funding spotted

A biotech company has landed a more than $13 million grant from the Cancer Prevention and Research Institute of Texas.

The nearly $13.3 million grant given to OncoResponse — which is relocating from Seattle to Houston, according to CPRIT's news release — will help the company develop fully human monoclonal antibodies for treatment of cancer that otherwise would not respond to immunotherapy. OncoResponse already has a partnership with MD Anderson Cancer Center, which is one of the company’s investors.

“We are thrilled to receive this recognition from CPRIT in supporting the potential of our immunotherapy candidate OR502. We greatly appreciate the additional support from our investors as we continue to make significant progress with our drug development efforts advancing immunotherapies derived from clues of Elite Responders,” says Clifford Stocks, CEO of OncoResponse, in a news release.

Aside from the grant, OncoResponse just hauled in $14 million from existing investors in a round led by RiverVest Venture Partners. Other participants in the series D round include Venture Partners, Canaan Partners, 3B Future Health Fund, Bering Capital, Takeda Ventures, and InterVest Capital Partners.

To date, OncoResponse has raised more than $180 million, according to market research company CB Insights.

A representative of OncoResponse couldn’t be reached for comment about the company’s relocation to Houston.

MD Anderson and Seattle-based Theraclone Sciences launched OncoResponse in 2015. Rice University was among the inaugural investors.

OncoResponse’s OR2805 immunotherapy product is being evaluated in a Phase 1 clinical trial. It’s the company’s leading immunotherapy candidate. OncoResponse is also working on OR502, an antibody being prepared for investigational and clinical studies.

“The modern treatment of cancer activates the body’s own immune system to attack cancer,” OncoResponse says in a summary posted on the website of the Cancer Prevention and Research Institute of Texas (CPRIT).

“These treatments, called immunotherapy, may not be successful if the cancer can recruit bad-acting cells, such as tumor associated macrophages, or TAMs, that create barriers preventing immunotherapies from activating the body’s own defenses against the cancer. To find drugs that may help counteract these TAMs, OncoResponse looked to patients who had responded very well to immunotherapy to see if their bodies made factors to block TAMs and helped them fight their cancers.”

OncoResponse’s OR502 prevents TAMs from shutting down the body’s response to cancer, thus restoring tumor-killing immune activity, CPRIT explains.

In addition to OncoResponse, recent CPRIT grant recipients from the Houston area are:

  • Houston-based 7 Hills Pharma, $13,439,001. The company is working on immunotherapies for treatment of cancer and prevention of infectious diseases.
  • Houston-based Allterum Therapeutics, $11,721,150. The company is coming up with an antibody for treatment of patients with acute lymphoblastic leukemia. This type of cancer affects blood and bone marrow.
  • Houston-based Cell Therapy Manufacturing Center, $9.1 million. The center is a joint venture between National Resilience and MD Anderson Cancer Center that is developing cell therapy manufacturing technologies to support biotech partnerships.
  • Houston-based Pulmotect, $8,851,165. The company’s PUL-042 product is aimed at treating and preventing respiratory complications in cancer patients.
  • Cancer researcher Michael King, $6 million. The grant helped lure King to Rice from Nashville’s Vanderbilt University, where he’s been the chair of biomedical engineering. King’s lab at Vanderbilt has been testing therapies for metastatic breast cancer and prostate cancer.
  • Missouri City-based OmniNano Pharmaceuticals, $2,711,437. The pharmatech company is working on two drugs for treatment of solid tumors in patients with pancreatic cancer.

“Texas is unique because of CPRIT’s ability to invest in cutting-edge research when private capital is scarce. This is yet another way Texas is leading the nation in the fight against cancer,” Wayne Roberts, CEO of CPRIT, says in a news release.

Houston neck-and-neck with Austin in third quarter venture capital funding reports

It's on

It was a Texas showdown when it came to venture capital funding between Houston and Austin in the third quarter of 2018. According to Crunchbase data, Houston startups pulled in $138.8 million — 39.2 percent of the state's entire VC funding — while Austin startups reported receiving $150.6 million — 42.6 percent of the funds.

"It's something we've never even come close to before and, all of the sudden, boom, we're right there," Station Houston CEO Gabriella Rowe tells InnovationMap. "I think that's what we are going to continue to see in Houston."

"We're not going to see little wins now. We're going to start seeing big wins."

Before the startup scene can truly celebrate, it's worth noting that the entire state struggled in the third quarter. VCs contributed $353.7 million to Texas startups in 91 known deals, according to the report. That's less than half of what was reported in the second quarter, and, actually, it's less that what Austin alone received in Q2. However, the state is up year-over-year in VC funding by 11 percent, as the state only saw $319.6 million in Q3 of 2017.

Crunchbase reported that the largest four funding rounds in Houston were as follows:

  • OncoResponse (immuno-oncology): $40 million in September
  • ViraCyte (biopharmaceuticals): $30 million in September
  • Enchanted Rock LLC (utilities): $23.6 million in July
  • DNAtriX (cancer treatment): $15.5 million in September

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.”
