Houston-based Solugen, a startup that specializes in combating carbon dioxide emitted during the production of chemicals, has hauled in $357 million in a Series C funding round. That amount eclipses the size of any Houston VC funding round this year or last year.

The Series C round lifts Solugen's pre-money valuation to $1.5 billion, according to the Axios news website. This gives Solugen "unicorn" status as a startup with a valuation of at least $1 billion.

Singapore-based GIC and Edinburgh, Scotland-based Baillie Gifford led the round, with participation from Temasek Holdings, affiliates of BlackRock, Carbon Direct Capital Management, Refactor Capital, and Fifty Years.

Since its founding in 2016, Solugen has raised more than $405 million in venture capital, according to Crunchbase.

"Solugen's vision for cleaner chemicals through synthetic biology has the potential to be a fundamental shift in how chemicals are made, to help tackle the environmental challenges we face globally. The chemical market itself is colossal, and Solugen is just getting started," Kirsty Gibson, investment manager at Baillie Gifford, says in a September 9 news release.

Solugen's patented Bioforge processes produce "green" chemicals from bio-based feedstocks. These chemicals are aimed at reducing or eliminating carbon emissions from chemical producers. The Series C funding will help Solugen expand the Bioforge platform and broaden the reach of Solugen's products.

Carbon dioxide from chemical production ranks among the greatest contributors to industrial greenhouse gas emissions.

CNBC explains that Solugen designs and grows enzymes that can turn sugar into chemicals needed to make an array products used in many industrial settings. The company's bio-based chemical offering already includes water treatments, a chemical that makes concrete stronger, another chemical that makes fertilizers more efficient, and detergents that are strong enough to clean a locker room or mild enough to be used for facial wipes, according to CNBC.

"This fundraising round allows us to continue expanding the footprint of our Bioforge technology to give industries the products they need to reduce emissions in their existing supply chains, without compromising on performance or economics," Sean Hunt, co-founder and chief technology officer of Solugen, says in the news release.

Three days before the funding announcement, Solugen made news of a different sort.

Axios reported September 7 that Solugen plans to open a new R&D facility outside Texas because many of the state's social policies — including its abortion restrictions — are making it hard to recruit employees.

Solugen employs about 115 people, most of whom work from its Houston headquarters, Axios says. The startup plans to more than double its R&D capability over the next two years, representing around 100 jobs, with most of those workers expected to be assigned to a new facility that will be set up in California or Massachusetts.

"We want to make sure we're hiring the top enzymologists and chemical engineers," Solugen CEO Gaurab Chakrabarti tells Axios. "We've come to the conclusion after talking to lots of candidates that they want to join Solugen, but they don't feel comfortable coming to Texas, so for us it's become a no-brainer to have R&D facilities elsewhere."

Houston startup raises $2.4M for sleep apnea technology

sleep score

Houston-based Bairitone Health has closed an oversubscribed seed round and achieved a regulatory milestone, the company tells InnovationMap.

The healthtech startup, which is developing solutions and technology for untreated obstructive sleep apnea (OSA), raised $2.4 million, says CEO and co-founder Meagan Pitcher, exceeding its $2 million goal.

New York-based Golden Seeds, which invests in female entrepreneurs, led the round. Houston-based South Loop Ventures also participated, as well as MALIAM, Impact Invest Her and additional angel, venture, syndicate and family office investors. The company previously raised a pre-seed round of $435,000 in 2024.

Pitcher says the latest funding will go toward Bairitone's clinical site expansion, FDA-facing work and the continued product development of its SOMNAR technology.

"What I’m most excited about is what this lets us do next: expand our clinical testing, work with more patients and physicians, and keep improving based on what we learn," Pitcher said in a LinkedIn post.

SOMNAR is the company's noninvasive diagnostic platform for sleep apnea airway assessment. The platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient.

SOMNAR received Breakthrough Device Designation from the Food and Drug Administration in April. It is currently for investigational use only and is still pending FDA clearance. The new designation aims to help speed up development, assessment and review for premarket approval for medical devices, according to the FDA. It will also give Bairitone more opportunities to interact directly with FDA experts to make the approval process more efficient.

Bairitone was founded in 2022 in the Texas Medical Center's Biodesign program by Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators.

The company was a finalist for the Houston Innovation Awards in 2025 and 2024.

Houston university to launch master’s in artificial intelligence

AI experts

Houston’s Rice University will welcome students to its new Master of Artificial Intelligence (MAI) program next fall, the college announced last week.

The program, which will begin taking applications this fall, is geared toward students with a computer science background as well as working engineers, scientists and technologists as they pursue careers that create and deploy AI. It will be part of Rice’s Department of Computer Science.

The new graduate degree comes after Rice created its Bachelor of Science in AI program in 2025.

Students enrolled in the 30-credit-hour, non-thesis professional degree program will prepare for prospective jobs as AI architects, applied AI researchers and AI and machine learning engineers, according to a news release.

“AI is rapidly moving from research laboratories into the systems that shape how we work, learn and solve complex problems,” Luay Nakhleh, Dean of the George R. Brown School of Engineering and Computing, said in the release. “The MAI will give students the technical depth and practical experience to build these systems responsibly.”

The on-campus degree program will include coursework in AI foundations and traditional, hands-on learning over its three-semester duration. Students will have easy access to faculty and have the opportunity to collaborate in small cohorts. The program includes a required internship before completion.

Chris Jermaine, chair of Rice’s Department of Computer Science, says Houston is well-positioned to connect students with industries where AI is increasingly being used, including health care, energy, aerospace, finance and technology.

“The Master of Artificial Intelligence reflects the graduate education Rice is working to advance: rigorous, forward-looking and connected to the challenges graduates will encounter in their careers,” Jermaine said in the release. “Combining strong academic foundations with practical experience will prepare students to contribute thoughtfully and responsibly as AI continues to evolve.”

Other Texas universities offer similar degrees, like Texas A&M's online Master of Science in Artificial Intelligence, Baylor’s Master of Science in Artificial Intelligence (MSAI+), University of Houston Downtown’s Master of Science in Artificial Intelligence program, and University of Texas at Austin’s online master’s in AI.

MAI works as part of Rice’s Momentous strategic plan that incorporates responsible AI use, according to the university.

Tech giant Meta opens first Texas retail store in Houston's Galleria

Metaverse

Social media giant Meta has arrived in Houston with a new store that allows shoppers to go hands-on with all of its products. The Meta Lab, which offers an immersive retail experience, is now open daily on level two of the Galleria.
