Mitrix Bio
Mitrix Bio is a Bay Area biotech startup building bioreactor-grown mitochondria - the cell's power plants - packaged into vesicles it calls 'Mitlets' and delivered by injection. Founded by former SLAC accelerator manager Tom Benson, the company treats the slow decline of mitochondria as a root cause of aging and aims to manufacture autologous, young mitochondria at industrial scale so clinicians can regenerate organs, boost immunity and cognition, and extend healthy human lifespan toward 130 years.
HebeCell Corp
HebeCell Corp is a Natick, Massachusetts biotech developing allogeneic, off-the-shelf cell therapies grown from induced pluripotent stem cells (iPSCs). Its core invention is a suspension-bioreactor platform, ProtoNK, that produces natural killer (NK) cells indefinitely and at scale - a manufacturing approach the company says no other lab can match. Founded in 2016, HebeCell aims to make cancer and degenerative-disease therapies cheaper, safer, and available without a matched donor, under the tagline 'Incurable no more.'
Stämm
Stämm is a deep-tech biomanufacturing company building a desktop-scale, 3D-printed, bubble-free bioprocessor that replaces the giant stainless-steel tanks of conventional pharma. Founded in Buenos Aires and headquartered in San Francisco, the company is pursuing a vision of decentralized, AI-driven production of biologics and cell therapies.
Wildtype
Wildtype is a San Francisco-based cultivated seafood company that grows real salmon from fish cells in stainless steel bioreactors - no fishing, no farming, no ocean required. Founded in 2016 by a cardiologist-turned-food-scientist and a former U.S. Foreign Service officer, the company received FDA clearance in May 2025, making it the first cultivated seafood product approved for sale in the United States. With $123.5M raised and backing from Jeff Bezos, Leonardo DiCaprio, and Cargill, Wildtype is betting that the future of seafood is grown, not caught.
