When Avi Ravishankar decided to train for a marathon in high school, he wanted to find a training buddy. He got lucky, and one found him: his classmate, Julian Se, took on the task.

"Julian decided he was going to train with me — he's a strong personality," Ravishankar says. "We started training, and to this day, we just became best friends from there."

Usually, finding fitness friends and training buddies isn't that easy — especially in a huge, spread out city of Houston. Ravishankar and Se turned their friendship into a business partnership to solve this problem. Houston-based Muvve is a mobile app that's mission is to connect fellow fitness enthusiasts across the city. The two came up with the idea as a way to merge their passions.

"The only idea we had was we wanted to have a startup with running," Ravishankar, co-founder of Muvve, says. "We loved running and tech, so we just wanted to find a way to bridge the gap there."

Ravishankar, a Rice University alumnus, says he took his idea to Owl Spark, an early stage accelerator on campus, and they just started asking people about their pain points when it came to working out.

"The big two things that we found were accountability and motivation," he says. "Out of 100 people, I would say all 100 people said that."

Ravishankar, who worked for six years in engineering at Oxy, says that these pain points are actually pretty inherent to individual sports.

"Intrinsic motivation is hard to find, especially in individual sports, like running, cycling, or yoga," he says. "Whereas, in team sports, like basketball or volleyball, you have the team to train with and motivate you."

The app, which launched in May of 2018, acts like a network for fitness lovers — just like a dating app would connect potential romantic partners. Dating apps, actually, were a big influence on Ravishankar, he says.

"I fell in love with dating apps. It was this mind-blowing idea for me of how many people you can connect with — even if it's not for dating," he says. "The amount of people I have met just through technology always blows my mind. There's so much power in it."

Through his experience as an instructor at Black Swan Yoga, Ravishankar also realized boutique fitness studios needed a place to market their events to a wider audience. This gave Ravishankar an idea of a way to bridge the gap between different fitness studios around town via the app.

"For us the goal is to have all of these events and activities to go and meet like-minded people," he says.

Muvve's goal is to have these managed market events that are curated to ensure quality, rather than the hit or miss aspect of existing platforms.

"For me the curation aspect makes for a better experience," Ravishankar says.

Now, Muvve is focused on growing its user base from 4,500 to 10,000 users by summer. Simultaneously, the company is hoping to launch its first seed round of funding, and then using its funds and its network to launch into Austin by summer.

Ravishankar says finding potential investors has been the most challenging aspect.

"There's no money in Houston for a fitness tech startup," he says. "That space isn't really respected. For me, it's kind of a trickling effect. If there's no money in it, there's no one really to help you because they don't have a vested interest."

While funding has been daunting, Ravishankar says he's had some success in hiring out his team of developers, despite the uphill battle of hiring tech talent in Houston.

"There's hidden talent, but it's not obvious talent," Ravishankar says. "I think that people get discouraged by hiring in Houston because of that."

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
