Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes three innovators across Houston's energy transition.

Bobby Tudor, board chair of Greentown Labs

Greentown Labs, a climatetech incubator with locations in the Houston and Boston areas, has announced it has received $4 million in funding from both of the Houston and Massachusetts locations. Houston investors included Bobby Tudor, CEO of Artemis Energy Partners and chairman of the Houston Energy Transition Initiative, who also joins the organization as board chair.

“The challenges of the energy transition are immense, and the role played by technology incubators like Greentown Labs is essential,” Tudor says in a news release. “We believe this role, which is a partnership between academia, industry, philanthropists, entrepreneurs, and governments, is the best way to get to effective, scalable solutions in a time frame that the urgency of the challenge requires. We need all hands on deck, and this partnership between Massachusetts and Texas can be a role model for others.” Read more.

A Houston company that's responding to rising energy demand by harnessing geothermal energy through its technology has again secured millions in funding. The deal brings Fervo's total funding secured this year to around $600 million.

Fervo Energy announced that it has raised $255 million in new funding and capital availability. The $135 million corporate equity round was led by Capricorn’s Technology Impact Fund II. The funding will go toward supporting Fervo's ongoing and future geothermal projects.

“The demand for 24/7 carbon-free energy is at an all-time high, and Fervo is one of the only companies building large projects that will come online before the end of the decade,” Fervo CEO and Co-Founder Tim Latimer says in a news release. “Investors recognize that Fervo’s ability to get to scale quickly is vital in an evolving market that is seeing unprecedented energy demand from AI and other sources.” Read more.

Casey Brown, executive director of Evolve Houston

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced.

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.” Read more.

13 initiatives receive grant funding from new EV-focused, Houston-led program

driving toward net-zero

Evolve Houston awarded its inaugural microgrants this week to 13 groups, neighborhoods and an individual working to make electric vehicles accessible to all Houstonians.

Launched in 2022, Evolve's eMobility Microgrant Initiative supports community efforts that propose electric vehicle, micro-mobility and charging infrastructure projects in some of Houston's most underserved neighborhoods. The grants ranged from $10,000 to $15,000.

Shell, NRG, CenterPoint, the University of Houston, and the city of Houston are partners in Evolve Houston. GM and bp America helped found the microgrant program.

“The eMobility Microgrant Initiative is a culmination of my vision and the collaborative efforts from many individuals and corporate supporters who recognize the importance of the transition to electric transportation,” Houston Mayor Sylvester Turner says in a statement. “The grant winners we recognized today are trailblazers in their communities, leveraging EV technology to residents in neighborhoods that have been historically underserved.”

Winners of the Round 1 eMobility Microgrants and their proposed projects included:

  • Alliance for Multicultural Community Services: Adding a charging station for the Gulfton area and a youth advocacy initiative
  • Third Ward Real Estate Council & Northern Third Ward Neighborhood Implementation Project: Introducing an interactive “mobility hub” to show what EV infrastructure would look like in Third Ward
  • Coalition of Community Organizations: Bringing eBikes and a charging station in the Fifth Ward
  • Edison Arts Foundation: Installing an EV charging station and green energy awareness at the Edison Center in Fort Bend
  • GROW: Promoting green energy careers to youth in underserved communities through EV education and outreach events

  • South Union Community Development Corporation: Creating a workforce development program for green energy careers
  • The Reflections of Christ's Kingdom (The R.O.C.K.) Church–BroadwayCampus: Adding a DC-Fast charger in the South Houston/Hobby Airport area
  • University of Houston-Downtown: Installing a no-cost EV charging station on campus

“This program is designed to provide launch funding to community-based, EV ecosystem-related projects," says Evolve Houston President and Executive Director Casey Brown. "We see significant opportunities to make meaningful progress by using an exciting new technology that is centered around community-based direction. Our governance system puts the community in charge and knows that the ideas of those that know their communities best will carry the greatest impact.”

Applications for the second round of microgrants are now open.Information can be found here. The application deadline is Friday, September 22, 2023.

Evolve Houston was founded in 2019 through Houston's Climate Action Plan. The nonprofit relaunched in 2022, naming Brown as its new president and executive director. The organization's main goal is to improve air quality, reduce greenhouse gas and to accelerate EV adoption so that half of all new vehicles sold in the Houston area would be EVs by 2030.

Houston nonprofit relaunches, names new leader, and introduces electromobility initiative

evolve evolves

A Houston organization focused on promoting electromobility in Houston has announced some big updates.

Evolve Houston, founded in 2019 through Houston's Climate Action Plan, has relaunched as of its event Thursday, August 18. The nonprofit has also named Casey Brown as the new president and executive director. Formerly at Halliburton and Coretrax, Brown's appointment went into effect this month.

"I am honored to have been appointed by the board to lead Evolve into the next phase of our electric vehicle journey," says Brown. "I look forward to working with our partners to get more electric cars, buses, and bikes on the road, and to publish Evolve's electrification roadmap 2.0 early next year."

Additionally, thanks to funding from Evolve Corporate Catalysts General Motors and bp, the organization has introduced the eMobility Microgrant Initiative, which will facilitate a peer-review process to award microgrants to local electromobility projects. Applications for the grants are now open online and will be accepted through September 16 at 6 pm.

"Evolve Houston is committed to supporting a just transition to a more sustainable transportation system, so all residents can receive the benefits of eMobility," says Grace Millsap, Evolve Houston director of equity and investment, in a news release. "The Greater Houston area has made significant progress in improving livability. We must continue and bring the eMobility revolution to Houston's communities that remain disproportionately in need of a cleaner environment, better services, and diversified economic development.

"Evolve's eMobility Microgrant Initiative will empower and elevate residents' voices, drive further community investment, and prioritize the communities who are most impacted by climate and mobility challenges," she continues.

A community-focused initiative, the Equity Program has been established to address poor air quality and limited access to public transportation in vulnerable communities, per the release. This fall, Evolve will invest the microgrants into community-led efforts that are increasing access to all forms of electric mobility and EV charging stations.

"The Complete Communities Initiative bridges the gap between equity and opportunity for our city's most under-resourced and underserved neighborhoods. Residents living in the Complete Communities have made it clear that its past time to address the transportation and climate change challenges that impact their quality of life," says Shannon Buggs, director of the Mayor's Office for Complete Communities, in the release.

"Increasing chronic air pollution and lack of equitable mobility has disproportionately affected low-to-moderate income neighborhoods," she continues. "With the help of community leaders, the Evolve Houston Equity Program provides a pathway for our City to ensure that every resident lives in a healthy, sustainable and thriving community."

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
