Solugen is reinventing the trillion-dollar chemical manufacturing industry by combining biology and chemistry in a new way. In this episode of Hard Tech, YC's Jared Friedman visits co-founders Gaurab Chakrabarti and Sean Hunt at their Houston HQ to see how they went from a $7,000 PVC reactor to a billion-dollar company competing with industry giants. They cover the breakthrough behind their enzymatic + catalytic production, how they found their first customers, and why starting small and staying close to customers let them win in a capital-intensive industry.
Chapters:
00:00 - A New Kind of Chemical Plant
01:02 - Fusing Biology & Chemistry In a New Way
02:23 - The Eureka Moment: From Pancreatic Cancer to Hydrogen Peroxide
03:30 - Using A Sugar Feedstock Over Oil and Gas
04:22 - Proving Enzymes Work at Scale In Chemical Manufacturing
05:16 - The $7K PVC Reactor
06:44 - Finding First Customers at YC
08:12 - What The Co-founders Got Out of YC
09:33 - Seed Round to Bio Forge
10:32 - Scaling to a Full-Size Plant (Bioforge)
11:57 - The Future of American Manufacturing
12:29 - The Next Decade of Solugen
