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.

Houston startup raises nearly $2M to expand logistics SaaS platform

seed funding

A Houston company that's providing innovative unified scheduling software for the logistics industries has raised additional seed funding.

Houston-based Velostics Inc. raised $1.95 million, the company announced this week. The additional seed round follows a $2.5 million round announced in 2021. The Velostics platform optimizes scheduling for inbound and outbound trucks, saving companies money across the supply chain and resulting in fewer emissions from idling trucks.

“Scheduling is a major headache for all parties focused on reducing cost and delivering on high customer expectations — our cloud based solution is designed to go live in one day with no apps required,” Gaurav Khandelwal, founder and CEO of Velostics, says in a news release.

Houston-based Starboard Star Venture Capital led the round, and Flyover Capital and Small Ventures USA, both previous investors in Velostics, contributed too. Additionally, Mexico-based Capital Mazapil joined in as a new investor. The family office has close ties to a leading CPG company with a global footprint of manufacturing plants and distribution warehouses, per the news release.

“At a time where all costs are increasing, Velostics has a proven solution that brings real cost savings and more importantly, increased capacity to manufacturing facilities, warehouses and fuel terminals," Keith Molzer, founding partner at Flyover Capital, says in the news release.

Khandewal founded Velostics in 2019 after seeing the business opportunity through ChaiOne, a Houston software company he's run since 2009. In an episode of the Houston Innovators Podcast, he shared the story of Velostics and why he thinks the city has a great opportunity to be a leader in logistics technology.

Exclusive: Houston-based stadium ordering app closes near $1.3 million Seed round with plans to scale

Fantech

Fans across the country are headed to football stadiums this weekend to cheer on their teams, but only a few will have the luxury of ordering food, beer, and even merchandise from the comfort of their seats.

Houston-based sEATz has created a platform where fans can order just about anything their stadium has from an app. Much like any other ordering app, once the order is placed, a runner will pick up the food and deliver it to the customer for a small fee and a tip.

The startup is now preparing to scale up from seven venues to 10 before the year is over as well as launching a new version of the app thanks to an oversubscribed near $1.3 million Seed round led by Houston-based Valedor Partners. Houston-based Starboard Star Venture Capital also contributed to the round. SEATz has plans to launch its Series A round before the new year.

"We're building enterprise-level, scalable in-seat ordering, delivery, and pick-up software. We'll have all the data and validation we need this fall to really start to push that out," says CEO and co-founder Aaron Knape.

SEATz got its start when co-founder and COO Marshall Law missed a particularly amazing play by the Astros during a World Series gameduring a World Series game because he was waiting in line to get food for his family. In a world of Uber and Favor, it was time for stadiums to step up their convenience. Law and Knape had been friends for a while — they met through their wives — and they regularly bounced business ideas off each other.

"We would meet every couple weeks in the Heights for coffee and throw spaghetti at the wall. We knew we'd eventually find an idea together," Law says. "After I left that Astros game, I texted him from the parking lot and told him, 'I found it.'"

The duo teamed up with another friend, Craig Ceccanti —CEO and founder of Houston-based Pinot's Palette, which has locations across the United States — and created sEATz's parent company, Rivalry Technologies. The name's an homage to the fact that the men are from rivalry schools — Law went to the University of Texas, Knape went to Texas A&M University, and Ceccanti went to Louisiana State University.

Part of sEATz ability to grow so rapidly has been a series of key partnerships. A Rice University business master's grad, Knape got them a foot in the door at his alma mater, and sEATz's first game was at Rice last year. Then, the startup was connected to Jamey Rootes, president at the Houston Texans, at an event at The Cannon Houston. That partnership lead to an introduction with Philadelphia-based Aramark Corp., a global food service and staffing company. SEATz is a member of Cannon Ventures, as well as being a member company of Capital Factory, which has its Houston outpost at The Cannon.

"At this point, we know that fans want food in their seats," Knape says. "That concerns the concessionaires because they don't want an app that just helps them sell food, because they already have long lines. What we have on the back end actually helps them divert that traffic and reduce those lines."

Aramark got sEATz into the University of Houston's basketball games, but the university then switched their food service company to Delaware North. However, sEATz had proven itself to the athletic department at UH, and wrote it in Delaware North's contract that they will work with sEATz.

At this point, the growing company has contracts in Houston with NRG Stadium, UH's TDECU Stadium and Fertitta Center, Rice Stadium, and Constellation Field. SEATz also worked 71 games of the Corpus Cristi Hooks and recently had its first out-of-state expansion to the University of Southern Mississippi. In its first game on campus, sEATz saw over 700 downloads for just the first game.

"Now that we're there, Mississippi State and Ole Miss want it too," Knape says. "Our expansion is really coming on."

The team has big ideas for sEATz and Rivalry Technologies. SEATz has applications in all types of venues — music or entertainment and even resorts.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
