Houston startup funding surpasses $1B in 2025 despite national slowdown

by the numbers

Houston-area startups raised more than $1 billion in venture capital during the first half of 2025 — almost double the haul for the first half of last year.

According to the new PitchBook-NCVA Venture Monitor, Houston-area startups raised $417.2 million in the second quarter of this year, compared with $281 million during the same period last year. In the first quarter of 2025, local startups collected $607.5 million in venture capital, compared with $281 million during the same period a year earlier.

Based on those figures, Houston-area startups picked up slightly over $1 billion in VC during the first half of this year, compared with $535 million in the first half of 2024.

Nationally, startups gained almost $70 billion in VC in the second quarter, down 25 percent from the same period a year ago, the PitchBook-NCVA Venture Monitor says.

Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook, explained that “the VC landscape continues to navigate a fragile recovery” and is constrained by economic uncertainty.

However, startups in certain sectors are poised to attract a great deal of attention and venture capital over the next several years, according to the report.

“Companies operating in AI, national security, defense tech, fintech, and crypto — sectors aligned with the administration’s priorities — are attracting disproportionately more investor interest, and this trend will likely continue throughout President Donald Trump’s term,” the report says.

The AI sector accounted for 64 percent of VC deal value in the first half of 2025, according to the report.

Houston space companies land $150M NASA contract for vehicles and robots

space simulations

Houston-based MacLean Engineering and Applied Technology Services LLC, known as METECS, has received a five-year contract from NASA to develop simulations and software services for space-based vehicles and robots, with a maximum value of $150 million.

Two other Houston-area companies, Tietronix Software Inc. and Vedo Systems LLC, were assigned as subcontractors for the award.

"This award is a strong testament to NASA’s continued trust in the quality of our work and their confidence in our ongoing support of the human spaceflight program," John MacLean, president of METECS said in a release.

According to NASA, the awardees are tasked with providing:

  • Simulation and software services for space-based vehicle models and robotic manipulator systems
  • Human biomechanical representations for analysis and development of countermeasure devices
  • Guidance, navigation, and control of space-based vehicles for all flight phases
  • Space-based vehicle on-board computer systems simulations of flight software systems
  • Astronomical object surface interaction simulation of space-based vehicles
  • Graphics support for simulation visualization and engineering analysis
  • Ground-based and onboarding systems to support human-in-the-loop training

The contract is called Simulations and Advanced Software Services II (SASS II), and begins in October. This is the second time METECS has received the SASS award. The first also ran for five years and launched in 2020, according to USASpending.gov.

METECS specializes in simulation, software, robotics and systems analysis. It has previously supported NASA programs, including Orion, EHP, HLS, Lunar Gateway and Artemis. It also serves the energy, agriculture, education and construction sectors.

Tietronix Software has won numerous awards from NASA. Most recently, it won the NASA JSC Exceptional Software Award (2017). Some of its other customers include Houston Independent School District, Baylor College of Medicine, DARPA and Houston Methodist.

Video Systems offers software for implementing human-rated, AI and autonomous systems, as well as engineering services to address the needs of spaceflight and defense. The company has previously worked with NASA and METECS, as well as Axiom Space and defense contractor Lockheed Martin.

The three companies are headquartered near NASA’s Johnson Space Center in Houston.
