Imagine having to pitch your company to a famed investor who has made investments in over 200 companies — seven of which achieved unicorn status. Now, imagine having to do that onstage in front of an audience — in person and virtually viewing.

That was seven Houston entrepreneurs' morning on March 4 during Houston Tech Rodeo. Jason Calacanis heard from the founders and gave his feedback on their business models, as well as general pitch advice. While some of his notes were in the realm of constructive criticism, he stayed pretty positive — for the most part.

"If you're a founder, you're signing up for a 70 percent failure. It's basically a suicide mission, except you don't actually die. You just hit the reset button and go again," Calacanis says to the crowd.

Calacanis also has a great deal of optimism for the region itself, noting on the potential of the innovation ecosystem, and, as an aside, the local basketball team.

"There's no reason Houston as big as a center as Austin has become," Calacanis says. "All it takes is for some of the rich people to say, 'instead of investing in some bond or Wall Street somewhere where they don't know what's going on and to take it and pay it forward with an entrepreneur."

Here are the seven Houston companies that pitched fir Calacanis, as well as some of his feedback.

Topper Luciani, CEO and founder of Goodfair

Kicking things off was Topper Luciani, CEO and founder of Goodfair, CEO and founder of Goodfair. On a mission to counteract the pollution of fast fashion, the company, which launched in 2018, sells second-hand clothing using "mystery shopping," shipping all of their clothing in variety packs chosen according to a customer's size and taste. This eliminates the cost of photographing, measuring, lowering the price for both the customer and the company.

"Climate chance is Gen Z's crisis, and they are our customers," Luciani tells Calacanis and the crowd.

Goodfair expects to do $5 million in revenue this year, as well as raise its seed round. Calacanis give Luciani advice to make sure he answers the question of, in a world with recycled clothing stores and a growing need for environmentalism, why now?

Katharine Forth, CEO and founder of Zibrio

From NASA to your bathroom floor — Katharine Forth, CEO and founder of Zibrio, has found a new way to track balance. With her company, people can have the everyday ability to figure out how balanced they are on scale of 1 to 10. The scale gathers data from your weight, your postural control, your muscles and other factors to calculate the rating.

But Forth's business is split between two products — a consumer-focused scale and a scale made for medical professionals to use. Calacanis says it's one scale too many and to focus on just one for now. He compared the company to if Uber tried to launch its upgrades its made over the years all at once.

"You're coming out of the gate with UberPool and UberBlack. Big mistake," he says.

Amy Gross, founder and CEO, VineSleuth Inc

Picking wine out isn't rocket science, and yet, "confusion is costing the industry billions," says Amy Gross, founder and CEO, VineSleuth Inc. The company's custom algorithm is backed by research from sensory scientists at Cornell University, and relies on both data collection and machine learning to determine specific wines that will match an individual customer's tastes.

The B2B approach has launched in a few restaurants around town and, as of this week, the Houston Livestock Show and Rodeo's Wine Garden. But how Gross is currently approaching business isn't exactly attractive to investors.

"The business comes across as a small niche business, which is going to cause investors to run," Calacanis explains.

His advice is to use the technology to prove to restaurants and bars that they are overpaying for their wines.

Panos Moutafis, CEO and co-founder, Zenus Biometrics

What started as a convenient way to check into events is now a facial recognition solution to event data. Zenus Biometrics can scan faces of event attendees for security — but also for data analytics, says Panos Moutafis, CEO and co-founder.

While the tech company has already evolved, Calacanis saw even more potential for the software, comparing it to the iPhone. The device is used more for a camera and app usage than an actual phone.

"As technologists we build something," Calacanis says. "Then we find out what people actually use it for."

While based in Houston now, Moutafis mentions that he will soon be relocated to Austin.

Safir Ali, co-founder and CEO of Hamper

Safir Ali grew up in his parents' dry cleaning store, and he observed that the biggest inconvenience for customers was them trying to make it to the cleaners to get their clothes before it closed. His company, Hamper, aims to provide a solution as "the Red Box of dry cleaning." Customers can deposit their dry cleaning in a kiosk in their office building, and it will be delivered to pick-up locations.

Calacanis liked that Ali has a background in the dry cleaning business."It takes somebody who is so obsessed that they aren't going to give up," he says, adding that he liked Ali's story.

"When you have something new – something that's novel, you could get a lot of attention," Calacanis says. "For things that are not novel, you have to use performance. You have to use the metrics."

Dyan Gibbens, founder and CEO, Trumbull Unmanned

Trumbull Unmanned has created an enterprise software company to analyze data collected from drones flying over oil and gas sites. The technology allows workers to maintain a safe distance and still collect the information needed. Dyan Gibbens, founder and CEO, has secured some impressive contracts with companies, including Exxon.

Calacanis asked Gibbens about those contracts and how much they were usually for, but didn't like her first answer.

"Every answer we get as investors is, 'It depends,'" Calacanis says, explaining a "pro tip" for entrepreneurs. " You want to lead with some examples and get some ground truth. Sell us that ground truth."

Calacanis' next piece of advice for Gibbens was to add a second set of data collecting technology, such as a moisture sensor or heat sensor, creating two sets of data for clients.

"Being agnostic to how you solve the problem is [a big opportunity]. Also, that becomes an upsell," Calacanis says.

Ksenia Yudina, founder and CEO, UNest

UNest is using user-friendly app technology to set up college funds for millennial parents. And Founder Ksenia Yudina has gotten some great reception, which has caused financial advisers to take note and even reach out. But Calacanis says they are, in a way, the enemy for her product and she needs to not spread out her resources trying to partner with financial advisers.

"Part of being a successful founder is knowing what you need more and what to stay focused on," Calacanis says. "If you remain a product that people like, everyone is going to drown you in opportunities. And as CEO you have to know when to say no."

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.
