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."

SeebeckCell Technologies, while based in Arlington, Texas, is no stranger to the Houston innovation ecosystem. The startup was in the first class of the Rice Alliance Clean Energy Accelerator, participated in the MassChallenge Texas Houston cohort, and is a member at Greentown Houston. The company announced earlier this month a new Houston association as it was invited to participate in the Chevron Technology Ventures Catalyst Program to develop further their technology platform designed to recover industrial waste heat energy, increasing energy consumption efficiency, and eliminating battery replacement in IoT applications, according to a news release.

"SeebeckCell is excited to be supported by Chevron, a technology leader in the energy market," says Ali Farzbod, co-founder and CEO of Seebeckcell Technologies, in the release. "This is inspiring hope in the scientific community as we see Chevron continue to back commercializing academically developed technologies that provide potential solutions for addressing climate change. Through collaboration and partnership, we're able to grow our startup and we're grateful for participating in the Rice Alliance Clean Energy Accelerator that helped connect us with Chevron."

SeebeckCell Technologies is helping petroleum and gas industries and emerging markets solve energy waste with an innovative liquid based thermoelectric generator.

VenoStent Inc. has announced successful enrollment in its initial feasibility clinical trial. The med device startup is a tissue engineering company that's developing smart polymer wraps to transform the efficacy of the vascular surgery industry, which sees five million operations each year.

"We are very pleased to announce that we have successfully enrolled twenty end-stage renal disease patients in our initial feasibility study taking place in Asuncion, Paraguay," says Tim Boire, CEO., in a news release "After years of development, we are confident that our bioabsorbable wrap technology can have a positive impact on the lives of patients that require hemodialysis to sustain life. This is a major milestone toward our mission to improve the quality and length of life for end-stage renal disease patients, as well as others needing vascular surgery."

VenoStent is an alum of TMC Innovation's accelerator and has been named a most promising company by Rice Alliance.

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.

Houston booms as No. 2 U.S. metro for new home construction

Construction Boom

Driven by population growth, more residential rooftops are popping up across Houston and the rest of Texas than anywhere else in America.

Using data from the U.S. Census Bureau and Zillow, Construction Coverage found 65,747 new residential units were authorized in greater Houston in 2024. That figure landed Houston in second place among major metro areas for the total number of housing permits, including those for single-family homes, apartments, and condos.

Just ahead of Houston was the Dallas-Fort Worth Metroplex, which took first place with 71,788 residential permits approved in 2024. In third place was the country’s largest metro, New York City (57,929 permits).Elsewhere in Texas, the Austin metro ranked sixth (32,294 permits), and the San Antonio metro ranked 20th (14,857 permits).

Construction Coverage also sorted major metro areas based on the number of new housing units authorized per 1,000 existing homes in 2024. Raleigh, North Carolina, held the No. 1 spot (28.8 permits per 1,000 existing homes), followed by Austin at No. 2 (28.6), DFW at No. 3 (22.2), Houston at No. 4 (21.6), and San Antonio at No. 13 (13.6).

A Newsweek analysis of Census Bureau data shows building permits for 225,756 new residential units were approved in 2024 in Texas — a trend fueled largely by activity in DFW, Houston, Austin, and San Antonio. That put Texas atop the list of states building the most residential units for the year.

Through the first eight months of last year, 145,901 permits for new residential units were approved in Texas, according to Census Bureau data. That’s nearly 80,000 permits shy of the 2024 total.

Among the states, Construction Coverage ranks Texas sixth for the number of residential building permits approved in 2024 per 1,000 existing homes (17.9).

Extra housing is being built in Texas to meet demand spurred by population growth. From April 2020 to July 2024, the state’s population increased 7.3 percent, the Census Bureau says.

While builders are busy constructing new housing in Texas, they’re not necessarily profiting a lot from homebuilding activity.

“Market conditions remain challenging, with two-thirds of builders reporting they are offering incentives to move buyers off the fence,” North Carolina homebuilder Buddy Hughes, chairman of the National Association of Home Builders, said in a December news release. “Meanwhile, builders are contending with rising material and labor prices, as tariffs are having serious repercussions on construction costs.”

Houston startups closed $1.75 billion in 2025 VC funding, says report

by the numbers

Going against national trends, Houston-area startups raised 7 percent less venture capital last year than they did in 2024, according to the new PitchBook-NVCA Venture Monitor report.

The report shows local startups collected $1.75 billion in venture capital in 2025, down from $1.89 billion the previous year.

Houston-based geothermal energy company Fervo Energy received a big chunk of the region’s VC funding last year. Altogether, the startup snagged $562 million in investments, as well as a $60 million extension of an existing loan and $45.6 million in debt financing. The bulk of the 2025 haul was a $462 million Series E round.

In the fourth quarter of last year, Houston-area VC funding totaled $627.68 million. That was a 22 percent drop from $765.03 million during the same period in 2024. Still, the Q4 total was the biggest quarterly total in 2025.

Across the country, startups picked up $339.4 trillion in VC funding last year, a 59 percent increase from $213.2 trillion in 2024, according to the report. Over the last 10 years, only the VC total in 2021 ($358.2 trillion) surpassed the total from 2025.

Nationwide, startups in the artificial intelligence and machine learning sector accounted for the biggest share of VC funding (65.4 percent) in 2025, followed by software-as-a-service (SaaS), big data, manufacturing, life sciences and healthtech, according to the report.

“Despite an overall lack of new fundraising and a liquidity market that did not shape up as hoped in 2025, deal activity has begun a phase of regrowth, with deal count estimates showing increases at each stage, and deal value, though concentrated in a small number of deals, falling just [8 percent] short of the 2021 figure,” the report reads.
