The Postage, a Houston-based, full-service digital platform to help organize affairs to make after-life planning a smoother process for families, has announced the launch of a crowdfunding campaign through MicroVentures.

"This crowdfunding offering is selling crowd notes to raise maximum offering proceeds of $500,000 with a minimum investment of $100," according to a news release. "We currently anticipate closing this offering on April 4, 2022."

More information on this offering can be found at: https://invest.microventures.com/offerings/the-postage.

Emily Cisek co-founded the company after she experienced an overwhelming experience following a death in her family.

"I just knew there had to be a better way, and that's why I started The Postage," Cisek says on an episode of the Houston Innovators Podcast. "My background had historically been in bringing offline businesses online, and I started doing some research on how I could make this space better. At the time, there really wasn't anything out there."

Houston-based Cart.com, an end-to-end ecommerce services provider and Amazon competitor, has announced yet another new partnership. The company has teamed up with Extend, which provides modern extended warranties and product protection plans. The partnership means that Cart.com merchants have access to a new revenue stream and new ways to increase customer satisfaction by leveraging Extend's platform and technology-enabled proprietary insurance stack.

"Like Cart.com, Extend is fixing the fractured ecommerce ecosystem by providing a truly innovative, effortless, and easy-to-understand service for both merchants and their customers," says Omair Tariq, Cart.com co-founder and CEO, in a news release. "By creating seamless solutions to serve brands, we empower them to focus completely on their customers. The partnership with Extend fits squarely in this view; anyone who has wrangled with extended warranty claims in the past understands the friction involved. Extend is rewriting the rules for product protection and customer service while Cart.com takes care of everything from the factory floor to the customer door. Through this partnership with Extend, we're now seamlessly covering the post-purchase experience too."

Extend launched in 2019 — a time when only the top 1 percent of merchants could offer extended warranties and protection plans to help their customers, according to the release. Now, Extend is valued at $1.6 billion, has raised over $315 million in venture capital, is on track to sell more than three million protection plans in 2021.

"The relationship between an ecommerce company and its customer doesn't end with the sale," says Woodrow Levin, co-founder and CEO of Extend, in the release. "Our technology will allow Cart.com's clients to continue to engage customers after they make a purchase, unlocking opportunities to increase brand loyalty, open new revenue channels, and create lasting customer relationships. Together, we're empowering clients to deliver a better experience for customers and we are excited to continue to build on that vision."

Campus Concierge rebrands to Clutch with revamped website

Campus Concierge is now Clutch, the Houston-based startup announced on its Facebook page last month. The new name also came with a revamped website.

Madison Long and Simone May had the idea for the company when they were undergraduate students at Purdue University and their only option for scoping out basic services — like getting their hair done or hiring a DJ for an event or a photographer for graduation photos — was to ask around among older students. Launched earlier this year, the platform is a marketplace to connect students who have skills or services with potential clients in a safe way. The company, which was a member of DivInc's inaugural Houston accelerator, launched on three college campuses this year — Texas Southern University, Rice University, and Prairie View A&M.

"Building community is so critical given the fact that it's nerve-wracking any time to ask someone for help — especially now that you are coming back to school after a year of being virtual," Long, CEO and co-founder of Clutch, previously told InnovationMap.

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.
