Even despite a global pandemic, two university-based summer startup accelerator programs were determined to continue on. And, that's exactly what they did.

University of Houston's RED Labs and Rice University's OwlSpark pivoted their summer program, which they put on collaboratively, to a virtual approach. On Thursday, August 6, the program's 16 startup teams pitched their projects at the seventh annual Bayou Startup Showcase.

Here are this year's Class 8 presentations:

EVA

Vascular access requires a medical team to use an ultrasound machine to help navigate a needle's precision during the procedure. However, 5 percent of procedures result in an inexact and painful outcome. OwlSpark company, EVA — which stands for Exact Vascular Access, has created a device that works with the ultrasound machine to endure navigation of the needle during the procedure.

CareSafe

Seven million people fall every year, but as great and helpful wearable devices are, they aren't foolproof. CareSafe, a RED Labs company, taps into home WiFi to visualize when a fall occurs and the company can even notify emergency contacts and emergency services.

Ai-Ris

People who live in underserved and rural areas don't have regular access to eye care — which means that these people are exposed to preventable eye diseases. Ai-Ris has created a portable, telemedicine-ready device that can help get these populations access to eye care.

Dividends360

Ninety million people invest in the stock market — and more than half of those investors are self directed and spending several hours a week on planning their investments. RED Labs company Dividends360 is a web-based platform to help the modern investor make his or her decisions in a more efficient way.

FirstGen Solutions

Expecting mothers can't take the majority of medications in the market because the effects of the chemicals on the unborn child is unknown, and testing is limited to costly, inaccurate, and highly regulated animal testing. FirstGen Solutions, an OwlSpark company, is producing a stem cell testing kit for pharmaceutical companies to use as an earlier and easier way to indicate potential risks a medicine could have.

nisa EFFECT

Women undergoing menopause have no control over their hot flashes, which can happen often, last up to 20 minutes, and be debilitating to daily activities. Nisa EFFECT has created a cooling bra so that the 80 percent of women who experience hot flashes during menopause can have a discrete way to cool down.

FreeFuse

Five hundred hours of video content is uploaded every minute, and the sheer oversaturation of the industry makes growing an audience extremely difficult for content producers. Interactive video platform FreeFuse, an OwlSpark company, wants to flip the script and allow content creators to see what its audient wants to see in terms of content.

Morpheus Health

Pharmaceutical companies don't make it easy to find out about side effects medicines can have on its users. Morpheus Health, an OwlSpark company, uses data and patient information to better customize and predict potential side effects a medicine can have. Morpheus's results don't replace prescriptions or doctor consultations, but instead allow the patient to take that information into the consultation room.

Phase Filter

​Changing the air filters is an easily forgotten chore that, if undone, can cause unnecessary air quality issues and a higher electricity bill for homeowners. Phase Filter has designed a self-scrolling air filter that's easy to install and only needs to be changed once a year,

Bloodhound

The OwlSpark and RED Labs summer programs are meant to help early-stage startups figure out their market need and determine whether or not their product is a viable business. The Bloodhound team explains how they came up with their idea for a software that helps detect bleed in surgeries, and then how they realized, after research and mentorship through the program, that it wasn't an idea worth pursuing. Doctors need more help with stopping bleeds than finding them.

Crew Trace Solutions

The Navy needs an upgrade to their accountability practice. That's where Crew Trace Solutions, an OwlSpark company run by two military veterans, comes in. The technology mirrors something like EZ-Tag where personnel onboard are tracked throughout the ship as they pass through sensors set up in doorways around the boat.

VAYL

Everyone dreads the discomfort and disappointment that usually comes with dental appointments. The oral hygiene tools on the market today aren't cutting it, says the VAYL team, a RED Labs company. VAYL has created a device that brushes the entire mouth in an optimal way for time and for cavity prevention.

MoodyCorium

Finding the right moisturizer is a costly and exhausting industry for women. MoodyCorium, an OwlSpark company, is working on a solution so that women can navigate the hundreds of products available on the market.

ElastEye

Half of the glaucoma patients could have had their disease prevented by better diagnostics — and that's exactly what ElastEye has developed. The RED Labs company has created a non-invasive, early detection device that determines the elasticity of the eye.

BitGrange

Supporting local farmers can be hard — it might raise the price of produce for consumers while orders tend to be smaller than farmers prefer. BItGrange, an OwlSpark company, created an e-commerce platform to allow consumers to go in on purchases together to create a win-win situation for both sides of the transaction.

dext

Simple daily tasks can be overwhelming to stroke survivors and the only solution is exercise and rehabilitation. Dext is a wearable tool to help take that exercise and rehab into a daily, easy to use setting.

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.
