Houston-based Solugen has announced an HQ move. But don't worry. This unicorn chemicals company is just moving down the street.

Parkway Property Investments LLC announced today that Solugen is relocating its Houston corporate headquarters to Greenway Plaza. The biotech company, recently ranked as one of the most innovative businesses in the world, signed a multi-year lease in Phoenix Tower. The building is one of 11 Class A buildings on the 52-acre mixed-use campus.

The space's buildout is expected to be completed in the second quarter, according to a news release, with Solugen moving in after that.

The venture-backed biotech startup, which produces high-performance chemicals through the use of bio-based feedstock and metal catalyst technologies, signed a multi-year lease in Phoenix Tower. The property is one of eleven Class A buildings on the landmark, 52-acre mixed-use campus, which is strategically located between Downtown and Uptown. Buildout of the space is expected to be completed in the second quarter.

“Innovative companies like Solugen are choosing to outsource the design-build process for office interiors to Parkway," says Eric Siegrist, Parkway’s managing director of leasing, in the release. "With several floors of ‘Ready Right Away’ suites fully-deployed, we happily take on this process to reduce the time and energy expended by an incoming tenant, resulting in expedited occupancy.”

Solugen was represented by Nick Terry, managing partner of Rifle Real Estate. Parkway’s senior director of leasing, JP Hutcheson, negotiated on behalf of Parkway.

Founded in 2016, Solugen’s process converts corn syrup into industrial chemicals, cutting down on carbon emissions generated by traditional production of chemicals. Carbon dioxide from chemical production is one of the biggest contributors to industrial greenhouse gas emissions. In September, the company raised a $357 million series C funding round and claimed its unicorn status.

Solugen joins several tech companies already housed in Greenway Plaza, including FlightAware, ThoughtTrace, Detechtion Technologies, and Buildforce.

3 tech companies ink deals in Greenway Plaza

Moving in

Three technology companies have executed new leases in Greenway Plaza. The leases represent over 20,000 square feet of space.

One of the companies has already moved in to the 52-acre Greenway Plaza, which is managed by Parkway Property Investments, LLC., while the others have move-in dates throughout the year.

"With renovations at Greenway 8 and 12 now complete, we're seeing broad-based interest from a variety of sectors drawn to an engaging, multi-faceted environment centered around convenience and collaboration with easy ingress and egress, a pedestrian-oriented layout, plus extensive and growing campus amenities such as the upcoming 80,000-square-foot Life Time Athletic club," says Parkway's COO, Mike Fransen, in a release.

Houston-based ThoughtTrace, Inc.is expected to move into its 4,358-square-foot space in Phoenix Tower the first quarter of 2019. The software-as-a-service startup uses artificial intelligence to make data entry and other tasks more efficient for oil and gas companies. The office will be the company's headquarters, and has regional sales offices in Dallas/Fort Worth, Denver, Oklahoma City, and Pennsylvania. Allie Hubbard, Brandi McDonald, and Christina Ott with Limestone Commercial brokered the deal on behalf of ThoughtTrace, while Rima Soroka and JP Hutcheson represented Parkway.

DMC, Inc., based in Chicago, is moving its Houston office from the Upper Kirby area to Greenway Plaza. The cross-industry software and engineering services company plans to set up 6,403-square-foot space in 8 Greenway Plaza in the third quarter of this year. DMC was represented by William Padon of CBRE and Parkway by Rima Soroka and JP Hutcheson.

Industrial Internet of Things platform, Detechtion Technologies, relocated its headquarters last month to a 12,000-square-foot space at 8 Greenway Plaza. Amanda Nebel and Eric Siegrist represented Parkway in the deal, while Detechtion Technologies was represented by Joshua Brown and Evan Roland of Newmark Knight Frank.

In addition to the three new tenants, the office park saw a few lease renewals from tech tenants including 30,000 square feet of new leases for NextSeed, Joule Processing, SkillGigs, and Marker Therapeutics, as well as an 8,000-square-foot renewal by a commercial operations enterprise software provider, according to the release.

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.”
