Downtown Houston has been fortunate to benefit from a transformation over the last couple of decades. Beautiful green spaces, luxury high-rises and hotels, restaurants, and updated arts and entertainment facilities are home to impressive art installations, farmers markets, major professional sporting events, and more. On the flip side of this, Houston’s central business district has seen a steep decline in commercial occupancy, struggling to bounce back to pre-COVID levels.

Houston is not alone in experiencing this situation. Nationwide, commercial vacancies are becoming increasingly noteworthy as the gap between residential rental rates and stagnant wages widens. Low-income earners, folks making between $20,000 and $30,000 annually (typically minimum wage employees, students and seniors living on Social Security), have been joining the ranks of the unhoused at an alarming rate due to the scarcity of affordable housing. Armchair economists and the like have been arguing for years that cities should repurpose these untapped resources into an opportunity to create dignified affordable housing that would keep those at risk off the streets and close to public transit options.

Pew Charitable Trust, along with international architectural firm Gensler, recently released their findings from a study on the subject — with Houston being one of two markets studied. The “Flexible Co-Living Housing Feasibility Study” found that converting Houston’s empty office buildings to communities of micro-apartments is, well, feasible.

“In the current climate of high construction costs, interest rates, building expenses, and rising rents, this project looks at the conventional office-to-residential conversion in a different way by leveraging the existing building infrastructure to reduce costs on a per unit basis,” Brooks Howell, principal architect at Gensler, tells CultureMap. “The result is a new housing typology, a co-living concept, that can provide affordable housing to the large and growing number of lower income single-person households in an urban context.”

The numbers
HUD reported that in 2024 homelessness was at an all-time high of 770,000 persons, up a staggering 18 percent from the prior year. Houston is on the low end of the national average, with a reported 3,270 homeless persons (4/10,000 Houstonians). CoStar data shows that Houston’s central business district contains 88 office buildings of over 50,000 square feet, 19 of which show reported vacancy rates of over 30 percent. As of November 2024, the median rent in Houston for an apartment was $1,297. The proposed rental rate for a furnished micro-apartment in a converted office building in downtown Houston is $700 — all inclusive, with zero move-in costs, as the units are fully furnished.

“The U.S. has a housing shortage of 4-7 million homes, which has driven rents to an all-time high and made it hard to save to buy a home,” Alex Horowitz, a project director for Pew Charitable Trust and a co-author of the study, adds. “Houston has one of the highest office vacancy rates in the U.S., but office layouts often don't work well for apartment conversions and carry high costs. This study finds that converting offices to dorm-style housing is cost-effective and can enable low rents — about $700 per month to live downtown. That could make a real difference for people struggling with high housing costs while revitalizing downtown.”

Co-living explained
Co-living is hardly a new concept. “Single room occupancy” dwellings, or SROs, were extremely common until about 1950. It’s worth noting that during the height of its popularity, homelessness was rare. The co-living model allows for a private furnished space, while bathrooms, kitchens, and laundry are shared facilities — much like a college dormitory. With 40 percent of renters being single occupants, this model promotes socialization and community, something that has been trending downward since the pandemic.

Wesley LeBlanc, principal analytics director for Gensler Chicago, adds that this elevated dorm situation is a “jumping off point for a number of models,” noting that there are six variations from the one in the study. LeBlanc encourages people to “Think beyond the conventional. A whole world of housing solutions come out of this.”

What to expect in a typical converted building
The Pew/Gensler report proposes a prototypical building standard of 24 floors, 19 of which are residential, with 60 micro-apartments per floor, or 1,140 residential units per building. Each floor would offer six shared kitchen areas, five larger shared living spaces, two smaller shared living spaces tucked into interior hallways, two central shower areas with five private shower rooms each. Two shower rooms would include toilets and sinks, plus two additional toilet rooms with four toilets and two sinks. The total comes to 10 showers, 12 toilets, and 14 sinks per floor. Two laundry rooms, each with three washers and dryers, would also be available per floor.

The high cost of converting office buildings into fully plumbed, individual studio apartments can be cost prohibitive, leading a pragmatic Howell to ask: “What if we didn’t demo everything?” The utilization of existing centralized plumbing on each floor saves an average of 25-35 percent in construction costs that would arise from running new plumbing to each unit.

The ground floor would consist of a main lobby, management office, and 10,000 square feet of retail space. Floors two through four would be reserved for parking, while the fifth floor would offer 10,000 square feet of Class B office space as well as amenities like the gym.

While subsidies will be required for the conversion, the same will not be true once the development is out of the construction phase. The co-living model is projected to cost around one-third of the cost of converting an office building to individual studio apartments or constructing new affordable housing.

Micro-apartments details
Each individual unit is designed to be 151 square feet, approximately the size of a modest hotel room. Furnishings include one extra-long twin bed (bedding included), a desk, chair, nightstand, standard-depth half-sized fridge, storage shelf, and cabinet. Units would have solid-core wooden doors and appropriate sound insulation — all for a tidy $700 per month.

Pricing has been a key factor in determining this configuration for affordable, urban housing. “Lowering the cost of housing to manageable levels enables residents to spend more on the other financial needs of their lives, which has broad implications for quality of life and well being,” LeBlanc explains.

Houston medical device startup implants artificial heart in first human patient

big win

Heart health tech company BiVACOR and The Texas Heart Institute announced that they successfully implanted the company's first Total Artificial Heart in a human at Baylor St. Luke’s Medical Center in the TMC.

The milestone is part of an FDA-approved early feasibility study that will test the safety and performance of the TAH device, which is based on a magnetically levitated rotor that takes over functions of a failing heart while a patient is awaiting a heart transplant, according to a statement from the organizations.

The "bridge-to-transplant" device could support an active adult male, as well as many women and children suffering from severe biventricular heart failure or univentricular heart failure.

"With heart failure remaining a leading cause of mortality globally, the BiVACOR TAH offers a beacon of hope for countless patients awaiting a heart transplant,” Dr. Joseph Rogers, president and CEO of THI and national principal investigator on the research, says in a statement. “We are proud to be at the forefront of this medical breakthrough, working alongside the dedicated teams at BiVACOR, Baylor College of Medicine, and Baylor St. Luke’s Medical Center to transform the future of heart failure therapy for this vulnerable population.”

BiVACOR received approval from the FDA for the early feasibility study in late 2023 and has four other patients enrolled in the study. At the time the study was approved, 10 hospitals were enrolled as possible sites.

“I’m incredibly proud to witness the successful first-in-human implant of our TAH. This achievement would not have been possible without the courage of our first patient and their family, the dedication of our team, and our expert collaborators at The Texas Heart Institute ... our TAH brings us one step closer to providing a desperately needed option for people with end-stage heart failure who require support while waiting for a heart transplant. I look forward to continuing the next phase of our clinical trial,” Daniel Timms, PhD, founder and CTO of BiVACOR, adds.

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. Globally, only about 6,000 heart transplants are performed each year, while 26 million people worldwide are affected by heart failure.

BiVACOR was founded in 2008 and maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, the company has raised nearly $50.8 million, according to CB Insights. The company raised $18 million in 2023, and $22 million in 2021.

Earlier this year, BiVACOR named a new CEO in Jim Dillon, a longtime executive in the medical device sector.

Last summer, Rogers joined the Houston Innovators Podcast to share his excitement with THI's innovations.

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

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.
