The Ion taps John Reale for startup and investor role

new hire

The Ion has named John "JR" Reale as its director for startups and investor engagement.

In his new role, Reale, a longtime leader in Houston’s startup ecosystem, will work to strengthen the innovation district's founder and investor network.

"Here’s what I’ve come to believe: the Ion is not just a building, not just a real estate play, and not just another innovation district. COVID, remote work, and shifting market dynamics changed the rules. Key ingredients like co-working, events, and community, while impactful, are no longer enough on their own," Reale shared on a LinkedIn post announcing the move. "What’s needed are advantages ... We need to intentionally design a system that repeatedly delivers advantages so founders can pull forward their visions."

Reale previously served as executive in residence and venture partner at TMC Venture Fund and co-founded Station Houston. He also serves as managing director of Integr8d Capital. He's an investor and serves on the board of directors for a number of venture-backed companies, including Cart.com, Lionguard and others.

The Ion will host "Today Is Day One – A conversation with John (JR) Reale" to welcome Reale to the role on Tuesday, Oct. 21. Reale will be joined at the event by Heath Butler, partner at Mercury, to discuss their thoughts on shaping Houston's founders ecosystem, as well as the Ion’s Founder Advantage Platform.

"On top of this connected architecture, we will build product. That product will be the Founder Advantage Platform to remove friction, compress time, and compound outcomes," Reale continued on LinkedIn. "This is the system that will drive repeatable experiences, and naturally, make these journeys so much more fun."

Houston-based startup secures fresh funding led by local investor to expand HVAC, plumbing platform

money moves

Houston-based SmartAC.com, which provides a customer loyalty management platform for contractors, has raised a follow-on round from Mercury Fund and other investors. The dollar amount of the round wasn’t disclosed.

An October filing with the U.S. Securities and Exchange Commission (SEC) indicates SmartAC.com planned to raise $8.2 million in venture capital. Of that sum, about $4 million had already been raised, the company reported, and nearly $4.2 million remained to be raised.

SmartAC.com's platform enables contractors in the HVAC and plumbing industries monitor, manage, and optimize their maintenance memberships through advanced sensors, AI-driven diagnostics, and proactive alerts.

“Growing a business in the trades is all about customer loyalty, and loyalty is driven by optimizing the customer’s experience,” Josh Teekell, founder and CEO of SmartAC.com, says in a news release. “SmartAC.com was built to perfect the experience of home comfort through data-driven insights that bring long-term value to homeowners and contractors alike.”

SmartAC.com says the new funding will enable expansion of its platform.

“Amid rising consumer demand for ‘smart home’ innovations, SmartAC.com is addressing a critical need for more sophistication in HVAC and plumbing through a technology-driven strategy,” says Heath Butler, a partner at Mercury Fund.

In 2020, SmartAC.com emerged from stealth mode and announced a $10 million series A round. The company raised a $22 million series B round in 2023.

Houston biotech startup selected to pitch at SXSW

austin bound

Houston biotech startup PHIOGEN is among 45 finalists that will present at this year’s SXSW Pitch showcase in Austin.

PHIOGEN is one of five food, nutrition, and health startups that will participate in the pitch competition, set for March 9 and 10. A panel of judges will listen to the pitches and then pick the winners. Since 2009, SXSW Pitch finalists have raised more than $23.2 billion in funding.

PHIOGEN has developed the world’s first biogenetics technology platform to harness the power of bacteriophages in the fight against serious drug-resistant infections. Bacteriophages — viruses that are found in bacterial cells — “are ubiquitous in the environment and are recognized as the most abundant biological agent on earth,” according to an article published in 2022 by StatPearls.

Founded in 2023, PHIOGEN is a spinoff of the Baylor College of Medicine’s TAILOR Labs. The startup, based at the Texas Medical Center’s Innovation Hub, has attracted more than $5 million in funding.

“Nothing about our treatments is fabricated; it boils down to creating natural environments that mimic real-life infections, driving biological changes to create ‘super phages’ against the superbugs,” Amanda Burkardt, CEO of PHIOGEN, said in 2023. “As a result, we receive high-performing phage fighters that are trained and ready to deliver safe and effective treatments for clinical applications.”

Professional services firm KPMG is the main sponsor of SXSW Pitch.

Six of this year’s SXSW Pitch judges are from Houston:

  • Heath Butler of Mercury Fund
  • Jesse Martinez of LSA Global
  • Trevor Purvis of the Houston Astros
  • Anu Puvvada of KPMG
  • Irene Tang of StartOut
  • Nate Thompson of HTX Sports Tech

“2024 is an exciting year for startups, and we are looking forward to showcasing these inspiring companies that are making waves in their respective industries and the world as a whole, as well as help connect them with the resources needed to continue advancing,” says Chris Valentine, producer of SXSW Pitch.

Houston experts: Diversity is key to venture capital success

force multiplying investments

Venture capital firms across the board have a goal of driving a return on their investments, but getting a good ROI and factoring in diversity and inclusion into the equation are not mutually exclusive.

In fact, on a panel at the HX Venture Fund's recent conference, Venture Houston, two investors focused on diversity and inclusion made the point that diversity is a key ingredient to successful investing. The panel, hosted by Michael Lipe, managing director at Insperity, consisted of Stephanie Campbell of The Artemis Fund and the Houston Angel Network and Heath Butler of Urban Capital Network and Mercury Fund.

"If you don't believe that diversity outperforms or that having diverse perspectives coming to the table helps your business outperform, then you probably have not been exposed to diverse thought," Campbell says on the panel.

And, as she continues, the proof is in the data "that diversity does outperform and can be a real force multiplier for your portfolio."

"In terms of returns, the Kauffman Fellows found that women-led teams generate 35 percent higher returns on investment than all-male-led teams," Campbell sites. "Pitchbook and All Raise found that women-led teams exit faster and at higher multiples than their all-male counterparts."

Butler recognizes that there's an emotional side of the discussion of diversity and inclusion — especially in this day and age — and that's nothing to disregard. But, he says, building onto that, VC is about discovering new opportunities — it's what VC funds' limited partners are expecting.

"From a more tangible perspective, we are in the business of finding untapped markets and opportunities to invest in and I believe our LPs expect us to leave no stone unturned," he says. "Ultimately you have to recognize that the hockey puck is moving in a direction where your LPs will require you to be looking under every stone to deliver a superior return."

Butler gives Mercury Fund as an example. At its founding, the team saw the middle of America as an untapped opportunity. The challenge is that investors tend to gravitate to ideas and people they know.

"So much of investing in early-stage innovation is intuitive, and investors will usually invest in what they know and resonates with them," Butler says. "But we have to recognize that there's a natural inefficiency in trying to relate intuitively to someone who's different from you."

The key is creating a team and mission with a clear intent and focus on measuring the impact. This goes down to hiring the right people with in your VC team as well as setting up a culture for diversity to succeed.

"If two hiring managers with similar needs," Butler says, "and one has a naturally inclusive mindset and the other feels pressure to meet a diversity quota — in the long run, which team will truly leverage and profit from a diverse perspective?"

Campbell says now is the time to invest in diversity — especially in Houston. During the pandemic, overall seed funding went up but funding for female founders reached a three-year low. Houston has a population doesn't have a racial majority — and that's what the entire country will look like in 2055, Campbell says.

"The opportunity we have in Houston to capitalize on diverse talent can really be a great opportunity to show the nation what can be done with that diverse talent pool," she says.

Houston also has an opportunity to support and invest in women or people of color who have been overlooked but have innovative solutions for society's most urgent problems.

"The more that we invest in diverse perspectives and diverse founders the more solutions, products, and services are going to come into the market for a broader populations and empower those economies to solve some of our deepest problems," Campbell says.

Both experts end on a call to action for their fellow investors: take inventory of the impact you have now and make intentional moves toward inclusion and equity — otherwise you're leaving money and talent on the table.

"If you don't have a diverse team, you don't have a diverse perspective, which means you have an incomplete perspective," Butler says. "You're missing out on opportunity to connect with people, purchasing power, and ultimately profits."

After 14 years at human resources company Insperity, Heath Butler has a specialty when it comes to thinking about the future of work. Butler was recently promoted within Mercury and the the move represents another aspect the firm is focusing on — something Butler discusses on last week's Houston Innovators Podcast episode.

"The world continues to be shaped by how the workforce and the workplace — and the actual work gets — done, and that couldn't have been put to the forefront more than during COVID," Butler says. "The promotion really reflects my focus on building out a very broad and deep theme for the firm around the future of work." Read more and stream the episode.

Serafina Lalany and her team at Houston Exponential have crunched the numbers again to look at what sort of venture capital deals Houston startups brought in last year.

According to her report based on Pitch Book data, the Bayou City dredged up $715 million across 117 VC deals in 2020 — a year marked by challenges and opportunities from the pandemic and the oil price drop.

In the report, Lalany found that 2020 VC trends in Houston included fewer, larger deals and a rise in angel investment. Read more.

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.
