About Hoxton Farms

Hoxton Farms grow cultivated pork fat, a healthy and delicious ingredient for the food industry. Cofounded in 2020 by Max Jamilly and Ed Steele, we are building the world's most scalable and cost‑effective tech stack for mammalian cell biomanufacturing – and we’re monetising it with a premium B2B ingredient. Hoxton Farms are a team of 50 based in London. We have raised from investors including Founders Fund, Collab Fund, FSV/F‑Prime and Global Brain.
