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 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.

Venus Aerospace closes $91 million Series B to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

  • Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
  • Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
  • Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.
