After closing its initial round of funding last year, Houston Exponential's fund of funds, called the HX Venture Fund, has closed its first investment on March 29. Austin-based LiveOak Venture Partners received a $5 million investment from the fund.

The HX Venture Fund raised $30 million after launching in October of last year. The fund's goal is to invest in out-of-Houston venture funds in the hopes that they reinvest that money into Houston startups.

"We invested in LiveOak Venture II because of the firm's compelling investment track record, expertise and vigor of the general partners, their extensive network of relationships with proven entrepreneurs, and their focus on capital efficient early stage technology companies in Texas," says Guillermo Borda, managing partner at HX Venture Fund, in a release. "LiveOak's team is committed to making a significant impact in the Houston startup ecosystem."

The HX investment is a part of LiveOak's Fund II, which was oversubscribed and closed at $105 million, the company announced today. According to a release from LiveOak, Fund II is a continuation to the firm's dedication to Texas entrepreneurship. The fund will focus on funding within the state's four largest tech hubs — Austin, Houston, Dallas and San Antonio — and have initial investments ranging from $2 million to $4 million, the release states.

The firm's portfolio focuses on seed and series A funding, and most of its investments are Austin-based, with the exception of three Dallas companies. LiveOak invested in Houston-founded CS Disco, an AI-enabled tool for legal business, but the company has since moved to Austin, according to a public relations representative. LiveOak also invested in San Antonio-founded Infocyte, but the company also relocated to Austin.

Houston has been a strategic market for LiveOak, says managing partner, Krishna Srinivasan, in the release, citing the city's recent entrepreneurial activity.

"We are excited to partner with HX Venture Fund and its strategic investment partners, comprising multiple leading Houston based corporations, to catalyze and grow this activity," says Srinivasan, in the release. "Given LiveOak's investment strategy of being the leading source of capital for entrepreneurs across Texas, we view this investment as highly synergistic with our efforts to enable world-class, category dominating companies coming out of Houston."

HX modeled its fund after the Renaissance Venture Capital Fund in Michigan, from which 10 outside venture capital firms benefitted. Renaissance Fund reported positive results from the fund of funds and Chris Rizik, CEO and fund manager of Renaissance, serves as a member of the investment committee.

Money moves

Houston Exponential closed the first round of funding for its fund of funds with $25 million in commitments from nine companies. The money will go to non-Houston venture capitalists to invest back into Houston startups.

HX Venture Fund's first-round partners include: Insperity, Chevron, Shell, Quanta Services, Westlake Chemical, The Plank Companies, PROS, HEB, and Camden.

Kingwood-based Insperity was the anchor investor, committing to $5 million last October, according to the release. The company also provided an undisclosed amount of resources support the operations of the fund as it launched.

"This is another transformational moment for Houston," says Gina Luna, chair of Houston Exponential, in the release. "From day one at Houston Exponential, we have been executing a plan to accelerate the growth of the ecosystem, including connecting Houston startups with the capital they need to grow their businesses. This is a significant, tangible milestone. Houston's leading companies have stepped up in a big way to make this happen, and this is a clear signal that Houston is committed to success."

Houston-based venture capital firm Mercury Fund's co-founder and managing director, Blair Garrou, chaired the fund's advisory board. He's also a board member for HX.

The fund of funds won't donate to Houston organizations directly, Garrou says in a statement. The fund's organizers had a different approach to growing funds in Houston's startup space.

"The HX Venture Fund will invest in venture capital funds outside of Houston – generating investment and interest in the region while increasing the investable capital available to Houston-based startups," says Garrou. "The HX Venture Fund is built upon a proven model that provides multiple benefits to its investors."

The benefitting venture capital funds haven't yet been named.

HX modeled the fund after the Renaissance Venture Capital Fund in Michigan, from which 10 outside venture capital firms benefitted —Mercury Fund was one of the 10. It was Garrou who led the movement to get Renaissance Fund's CEO and Fund Manager, Chris Rizik, as a part of the HX Venture Fund from the start as a member of the investment committee.

The Michigan fund launched 9 years ago and exceeded all expectations. For ever dollar Rizik and his team invested, $17 came back into the Michigan area, he told the Houston Business Journal. He says Houston has the same potential.

"I've spoken to many cities about Renaissance's fund of funds model and the impact it has had on Michigan," says Rizik in the release. "Houston has leaned into this model and it is impressive what they have been able to accomplish in a short time. It is a testament to the commitment of Houston's business and tech leaders to growing the ecosystem. It's really exciting to see."

In October 2017, Houston Exponential was launched by Mayor Sylvester Turner's Innovation and Technology Task Force in collaboration with the Greater Houston Partnership's Innovation Round Table and the Houston Technology Center. HX's launch included three main goals, according to the release: "make Houston a top 10 innovation ecosystem, generate $2 billion in venture capital annually and create 10,000 new technology jobs a year by 2022."

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.”
