A nearly 100-year-old building in downtown Houston is welcoming in entrepreneurs, small business owners, and enterprise firms with a new opportunity to innovate outside of traditional office spaces.

Esperson Flex — a coworking concept managed by Cameron Management in The Niels Esperson Building, which has stood out in Houston's skyline since its inception in 1927 — offers various membership tiers in its facility featuring private offices, desk space, conference room, and access to the overall area for freelancers. As an add-on option to the membership, members will have the opportunity to connect with other entrepreneurs through offering reciprocal daily use passes to Cannon members and allow them to book the conference rooms.

“Coworking allows small entrepreneurs to have a community and startup ecosystem that is very cheap and very flexible," Cameron Management CEO Dougal Cameron tells InnovationMap. “They can invest money in their enterprise instead of signing expensive long leases.”

Esperson coworkers have access to The Cannon's digital platform, Cannon Connect, which provides a digital platform for connections, resources, and services to investors, entrepreneurs, startups, and small businesses.

Currently, the offering of the venue is 12,300 square feet and 62 percent of it is leased.The company hopes to expand the coworking facilities to 62,000 square feet in the next five years, according to Cameron.

There are seven groups who are growing their own coworking business under the Esperson and Cameron Management umbrella, and some include working with groups that are specifically targeting often overlooked demographics, including Hispanic, Black, and female entrepreneurs. The Us Space, for instance, is a women of color-focused collective providing support and coworking for its community.

“We believe that entrepreneurship is the answer to many important problems in our world,” Cameron Management CEO Dougal Cameron tells InnovationMap.

In addition, the facility works with the Prison Entrepreneurship Program, which is a comprehensive re-entry program to help empower those trying to change their lives.

Located downtown, Esperson Flex is the latest in flexible work spaces by Cannon, which also include locations in the Energy Corridor, Houston Galleria, Galveston, The Woodlands, and, as of this week, Memorial.

Spaces like Esperson Flex have become increasingly popular for remote workers, and in some cases, have shown increases in overall productivity. In a survey conducted by Airtasker, remote employees worked 1.4 more days every month, than office workers, which equals 16.8 more days every year. In a similar survey by the Gartner 2021 Digital Worker Experience Survey, 43 percent said that flexible working hours helped them achieve more productivity.

The Cannon, too, has seen coworking and community-building opportunities from all corners of Houston, as the company's CEO, Jon Lambert, shared on the Houston Innovators Podcast.

Houston coworking company opens new Galveston hub amid profound growth and expansion

seaside innovation

The Cannon Houston has expanded its footprint throughout 2021, and one of the coworking company's newest hubs has opened its doors seaside.

The Cannon Galveston @ the MarMo is a new coworking space with membership options starting at $180 a month for entrepreneurs. The building is a former credit union space that Galveston real estate entrepreneur, Jimmy McClure, bought and renovated. McClure is also one of The Cannon's board members as of a couple months ago.

"We've always felt there was this opportunity to create this coastal innovation community," says Alex Gras, chief commercial officer at the Cannon. "And we found a great partner in Jimmy McClure."

In the aftermath of the pandemic, Gras says people are going to be more intentional about where they spend their time, and this location offers its member companies something different.

"Not only does Galveston have the allure of a coastal town with a more relaxed atmosphere, but it has some amazing support organizations," he says.

Gras is referring to the numerous innovative institutions on the island that have been operating in silos over the years — including University of Texas Medical Branch at Galveston, Texas A&M Galveston, Galveston College, Galveston ISD, Vision Galveston, and more. Gras says the feedback for The Cannon providing this neutral convening space for entrepreneurship has been so positive.

"Galveston really has the raw ingredients to become an amazing innovation ecosystem," Gras tells InnovationMap.

From a programming perspective, entrepreneurs can expect exactly what The Cannon has brought to its other locations. The team recently held a hacakathon in collaboration with The Ion, Vision Galveston, and UTMB — which was a major success, according to Gras — and plans to host a pitch competition on March 10.

"At the end of the day, entrepreneurs are looking for peers that they can do this with and not feel like they are so alone, as well as advisers, mentors, and coaches who help them think differently and investors who can provide some economic capital to help prop up their ideas," Gras explains. "Any programming we do in the future will have elements of social, networking, and education — but all in the confines of making sure we're providing all these different human, economic, and social capital to the entrepreneurs of Galveston."

It's not just toward the Gulf of Mexico where The Cannon has expanded profoundly this year. The company's sportstech hub opened in the Galleria area in collaboration with Braun Enterprises and Gow Media (InnovationMap's parent company).

"The thing that's exciting about this profound growth is it's reflective of the two driving initiatives of the Cannon — one being establishing a network of programmatically connected innovation hubs throughout the entire expanse of the city of Houston," says Lawson Gow, founder of The Cannon. "The other is looking for opportunities where Houston can go deep into an industry and be the best at that."

Sportstech is one of those avenues of opportunity, according to Gow, but the team is always looking for other verticals that might be a similar fit.

Additionally, The Cannon opened a new space in the Esperson building in downtown Houston. This space is small, says Lawson Gow, founder of The Cannon, but has room to grow.

"We want to create network of hubs — some in the community want highly-programed environments," Gow explains, adding that the Esperson Coworking likely won't feature the same level of programming as seen at some of the other locations.

Gow explains that he expects to grow the team at The Cannon to sport these expansions, crediting Gras for building and cultivating the team. Gras joined The Cannon in February.

"It wouldn't surprise us if we more than double our team within the next year," Gow says.

This profound growth comes after 18 months of uncertainty — which allowed Gow and his team to rethink some of their plans.

"Pre-covid had our eyes on expansion outside of the city, and we've dialed it back — it's been a healthy exercise", Gow says, "to reset our focus on the whole sprawl of Houston in setting up eight to 10 locations across the city so that we're truly democratizing access to all the tools entrepreneurs need to grow."

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.
