Tierra Biosciences

Tierra Biosciences (now rebranded as Revr) is a synthetic biology company that developed an AI-guided cell-free protein synthesis platform enabling high-throughput, on-demand production of custom proteins. Founded in 2015 by Dr. Zachary Sun, Dr. George Church, and Dr. Richard Murray as Synvitrobio and based in San Leandro, California, the platform decouples protein production from living cells to deliver 100x higher throughput, 10x faster turnaround, and dramatically lower costs compared to conventional cell-based methods. Customers across pharmaceuticals, biotech, agriculture, and food industries can order batches of hundreds of custom proteins through an e-commerce-style portal, generating rich AI-training data that continuously improves yield predictions and synthesis parameters.
