Biology as software
Zymergen was founded in 2013 in Emeryville, California by Josh Hoffman, Zach Serber and Jed Dean, three colleagues who had met at the pioneering synthetic-biology company Amyris. Their pitch was that microbial engineering, historically slow artisanal lab work, could be industrialized: pair high-throughput robotics with genomics, machine learning and data science to search vast genetic design spaces and 'biofacture' materials and chemicals that outperform petroleum-derived incumbents. Hoffman, a former McKinsey consultant, was the commercial and fundraising engine; Serber, a biophysicist, ran the science as chief science officer; Dean built the automation. It was a seductive thesis at exactly the moment capital was hunting for the next platform, and Zymergen positioned itself not as a drug company but as a horizontal engine that could make anything biology could make.
The SoftBank rocket
The money arrived fast and large. DCVC seeded and led a $44 million Series A in 2015; SoftBank led a $130 million Series B in 2016; and in December 2018 the SoftBank Vision Fund poured more than $400 million into a Series C that valued Zymergen near $1 billion, up from roughly $340 million months earlier. A $300 million Series D led by Baillie Gifford followed in July 2020. All told, Zymergen raised more than $875 million privately — Forbes later characterized the pre-IPO haul as north of $1 billion — making it one of the best-capitalized synthetic-biology companies in the world. What it did not have, underneath the platform narrative, was a scaled product actually generating revenue: 2020 product revenue rounded to roughly $13 million against annual cash burn well above $200 million.
