Tierra Biosciences is a San Francisco-based molecule and drug discovery company founded in 2015 by Zachary Sun, Ph.D., (C.E.O.), George Church, Ph.D. (Harvard), and Richard Murray, Ph.D. (California Institute of Technology).
In September 2018, Tierra Biosciences announced the closure of an oversubscribed $2.6 million seed funding round, led by Social Capital, with participation from Fifty Years and KdT Ventures. These announcements coincide with a name change to Tierra Biosciences. The name Tierra reflects the company's strategic focus of exploring naturally-motivated molecules from the world's soils and oceans.
