UNICORN
KoBold Metals applies machine learning, geosciences, and data fusion to identify new deposits of the critical minerals — copper, cobalt, nickel, lithium — needed for the energy transition. Founded in 2018 by Kurt House (CEO), Jenny Castro, Jeff Jurinak, and Josh Goldman, the company has raised nearly $1B across multiple rounds, backed by Breakthrough Energy Ventures, Andreessen Horowitz, BHP Ventures, Bill Gates, and Jeff Bezos. A $537M Series C in January 2025 — co-led by Durable Capital Partners and a pair of T. Rowe Price funds — pushed the post-money valuation to $2.96B. KoBold's flagship Zambian copper discovery is among the largest in decades.
