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.

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.

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 medtech firm secures $30M for neurosurgical robot

stroke surgery

Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.

Houston geothermal unicorn Fervo officially files for IPO

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

New UT Austin med center, anchored by MD Anderson, gets $1 billion gift

Future of Health

A donation announced Tuesday, April 21, breaks a major record at the University of Texas at Austin. Michael and Susan Dell are now UT Austin's first supporters to give $1 billion. In response, the university will create the UT Dell Campus for Advanced Research and the UT Dell Medical Center to "advance human health," per a press release.

The release also records "significant support" for undergraduate scholarships, student housing, and the Texas Advanced Computing Center for supercomputing research.

Both the new research campus and the UT Dell Medical Center will integrate advanced computing into their research and practices. At the medical center, the university hopes that will lead to "earlier detection, more precise and personalized care, and better health outcomes." The University of Texas MD Anderson Cancer Center will also be integrated into the new medical center.

That comes with a numeric goal measured in 10s: raise $10 billion and rank among the top 10 medical centers in the U.S., both in the next decade.

In the shorter term, the university will break ground on the medical center with architecture firm Skidmore, Owings & Merrill (SOM) "later this year."

“UT Austin, where Dell Technologies was founded from a dorm room, has always been a place where bold ideas become real-world impact,” said Michael and Susan Dell in a joint statement.

They continued, “What makes this moment so meaningful is the opportunity to build something that brings every part of the journey together — from how students learn, to how discoveries are made, to how care reaches families. By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond.”

This is the second major gift this year for the planned multibillion-dollar medical center. In January, Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed $100 million$100 million.
