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.

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.

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 startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
