Marco Lobba

Marco Lobba is a chemist turned CEO who co-founded CatenaBio (Catena Biosciences), a UC Berkeley spinout building a new way to staple proteins together. Trained in the labs of Nobel laureate Jennifer Doudna and chemist Matthew Francis, he turned a graduate-school enzyme trick into the CysTyr platform, where an engineered enzyme called Catenase forges a durable tyrosine-cysteine bond - the C-Y Bond - to assemble multi-payload conjugates that single-molecule chemistry could not. He was named to the San Francisco Business Times 40 Under 40 in 2025.
