Its Raptor platform aims to make monoclonal antibodies and other glycosylated proteins at a fraction of the capital cost and carbon footprint of conventional cell-culture bioreactors. Founded in 2024 and emerged from stealth in March 2026, the company raised an oversubscribed $23 million Series A in June 2026 and signed an early multi-product biosimilar deal with a major global pharmaceutical company.
