Revolutionary biotech company Coya Therapeutics Inc. (NASDAQ: COYA) may have closed its IPO in January 2023 for more than $15 million, but the company has made some of its most significant strides in the development of its lead product that prevents the further spreading of neurodegenerative diseases this year.

Known as COYA 302, the product uses a unique dual mechanism that is now being developed for the treatment of Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD), Parkinson’s disease and Alzheimer’s disease. The company published its phase 1 proof-of-concept study in the peer-reviewed journal Frontiers in Neurology that showed COYA 302's ability to stop clinical progression in ALS at 24 weeks in combination therapy, which helped earn the company a $5 million in strategic investment from the Alzheimer’s Drug Discovery Foundation to continue to develop the product for a planned Phase 2 trial focused on FTD.

Last year the company also added to its C Suite, naming Dr. Arun Swaminathan as chief business officer and Dr. Fred Grossman as president and chief medical officer.

Coya merged with Nicoya Health Inc. and raised $10 million in its series A in 2020.

NanoTech Materials, a chemical manufacturer that integrates novel heat-control technology with thermal insulation, fireproofing, and cool roof coatings to drastically improve efficiency and safety

Growing Houston startup moves into 43,000-square-foot facility amid 'hypergrowth phase'NanoTech Materials celebrated its move into a new facility — a 43,000-square-foot space in Katy, Texas, this week

Mike Francis, co-founder and CEO of NanoTech Materials, told InnovationMap earlier this year that it was in a "hype growth" phase—and meant it.

NanoTech, known for its proprietary Insulative Ceramic ParticleTM (ICP) that uses nanotechnology to optimize energy efficiency and heat control in the built environment, expanded into a new 43,000-square-foot facility this year and tripled its valuation in the last two years, according to its Innovation Awards application. The company also expanded into the Middle East and Singapore and successfully scaled up its NanoTech Cool Roof Coat to commercial markets.

The company closed a $5 million seed round in 2020 and an oversubscribed Series A round last year for $13 million. It was the first company selected for the Houston-based Halliburton Labs in 2021 and joined the Rice Alliance Clean Energy Accelerator in 2023.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
