Houston restaurateur pivoted his restaurant marketing business amid the pandemic — to a growing industry: aesthetics. Phil Sitter took the idea and tech he created with VIPInsiders to launch RepeatMD, a customizable marketing and fintech platform focused on the aesthetics industry, which includes plastic surgeons, dermatologists, etc.

Sitter, who serves as the company's CEO, says once he dived into learning about the industry, he found out these types of business are seeing incredible growth following the pandemic.

"They call it the 'Zoom boom' — everyone saw themselves on Zoom daily and decided to invest in themselves and their facial treatments." says Chris Chomenko, vice president of sales for the company, on the Houston Innovators Podcast.

"And they had the time," Sitter adds. "When you think about aesthetic procedures — whether its invasive or non-invasive, it takes time for recovery." Click here to read more.

Houston innovators find 'perfect storm' for fintech and marketing platform

Houston innovators podcast episode 129

Phil Sitter saw fast growth and adoption from his restaurant rewards platform he founded in 2019, but when the pandemic hit, he had to go back to the drawing board to find a growing industry that needed to be disrupted by his technology. And he did.

Sitter, a Houston restaurateur, originally founded VIPInsiders to help his restaurants — and later, licensing the technology out, other Houston eateries too — reward loyal patrons who continue to come in. However, in 2020, Sitter considered a pivot.

"We realized the restaurant industry may never be the same, and we asked ourselves who could be an ideal client," Sitter says on the Houston Innovators Podcast.

This pivot ended up creating RepeatMD, a customizable marketing and fintech platform focused on the aesthetics industry, which includes plastic surgeons, dermatologists, etc.

Sitter, who serves as the company's CEO, says once he dived into learning about the industry, he found out these types of business are seeing incredible growth following the pandemic.

"They call it the 'Zoom boom' — everyone saw themselves on Zoom daily and decided to invest in themselves and their facial treatments." says Chris Chomenko, vice president of sales for the company.

"And they had the time," Sitter adds. "When you think about aesthetic procedures — whether its invasive or non-invasive, it takes time for recovery."

After initially branching out into the field, Sitter says they are now onboarding up to 200 new locations a month, providing med spas around the world the ability to reward returning customers, as well as inform them on the breadth of options the facility offers. RepeatMD has expanded its team to 50 people and is eyeing seed funding this summer.

"Some things had to work out perfectly in order," Chomenko says, "for this perfect storm of perfect timing. Whenever you talk about entrepreneurs and how much of it was luck and how much of it is hard work, we really have attribute a lot of our success to being there with the right idea, in the right place, at the right time."

Sitter and Chomenko share more about the future of RepeatMD on the podcast episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Fast-growing Houston software startup expands with fintech model

innovative marketing

A less than one-year-old B2B software startup in Houston is beefing up its offerings with a new feature that thrusts it into the rapidly growing fintech space.

RepeatMD, founded in December 2020, specializes in white-label rewards apps for plastic surgeons, medical spas, dermatologists, and similar businesses. Now, it's expanding into the "buy now, pay later" fintech realm through a new deal with BTL Industries, a Marlborough, Massachusetts-based provider of body-sculpting equipment.

RepeatMD's new Medical Gym function enables customers treated with BTL equipment to finance add-on enhancement and maintenance packages through "buy now, pay later" (BNPL) arrangements. BNPL is a booming sector. The size of the global BNPL market approached $90.7 billion in 2020 and is projected to come close to $4 trillion by 2030, according to Allied Market Research.

RepeatMD essentially layers the Medical Gym's BNPL functionality on top of the rewards feature of its apps.

Chris Chomenko, vice president of sales at RepeatMD, says the startup already had been working on a BNPL offering when BTL approached the RepeatMD team about creating a BNPL product. RepeatMD and BTL share many of the same clients.

"We are rolling out with them nationally at a breakneck speed because the demand they have from their client base is so high," Chomenko says. "It's kind of forcing us to do in three months what we planned on doing in three years."

While the concept of a rewards app or a BNPL program is not unique, their pairing is, according to Chomenko. Sitter calls the marriage of the two a "game changer" — a game changer that eventually should extend well beyond BTL's clients.

RepeatMD founder and CEO Philipp Sitter says the Medical Gym feature lets customers break up the cost of, say, a $5,000 treatment into management monthly payments. The results of a survey of RepeatMD app users found that the guilt of putting down a wad of cash on aesthetics services was the No. 2 barrier cited in terms of spending money on treatments.

"What we'll be working on is being a full, proper fintech play, where we have that buy now, pay later functionality, and doctors can get paid in advance for treatments. But that is a large endeavor that will take us all of a year to [complete]," Chomenko says.

RepeatMD counts more than 600 practices in North America as customers. The startup envisions that figure rising to 1,000 by the end of this year. In tandem with that growth, RepeatMD foresees revenue climbing to eight figures (at least $10 million) by the end of 2022 and its valuation growing to nine figures (at least $100 million) by then.

Today, RepeatMD employs about 30 people. Sitter says the headcount should reach 75 to 100 by the end of next year.

Sitter is self-funding RepeatMD with proceeds from other business ventures, including Houston-based food and beverage loyalty and rewards platform VIPinsiders and Houston-based brunch and lunch restaurant EggHaus Gourmet. However, RepeatMD plans to raise outside capital in the first quarter of 2022.

The company sets up each client with an exclusive private-label app. RepeatMD says businesses using its app have seen an average sales increase of $313,000 and an average of 51 new referrals within the first 90 days of adopting the app.

Sitter says the RepeatMD rewards app provides a "gateway" for businesses to drum up repeat business and sell more services, much like the Starbucks rewards app incentivizes customers to try different food and beverage products.

"We see us becoming ubiquitous in the industry, where anybody that's a dermatologist, a plastic surgeon, or a medical spa has [our app]," Sitter says.

"We look at mobile app experience as something that's coming for all the local businesses. We're just the frontrunners in bringing it to the masses," he adds.

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.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

So, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.
