Nitricity
Nitricity is a Fremont, California climate-tech company turning air, water, renewable electricity and discarded almond shells into organic nitrogen fertilizer. Its flagship product, Ash Tea, replaces fossil-fuel-derived fertilizers with a regionally produced, OMRI- and CDFA-certified alternative that cuts emissions by more than 90%. Founded in 2018 by three Stanford PhDs, the company closed a $50M Series B in September 2025 and is building its first commercial plant in Delhi, California.
Kula Bio
Kula Bio is a Massachusetts climate-tech company turning naturally occurring nitrogen-fixing microbes into living fertilizer factories that run inside the soil. Born from Harvard chemist Dan Nocera's 'bionic leaf' research, the company supercharges Xanthobacter autotrophicus with a renewable-energy carbon source so the bacteria deliver plant-available nitrogen at the root zone, on demand. Field trials show its flagship Kula-N can replace as much as 80% of a farm's synthetic nitrogen use without the runoff or the fossil-fuel footprint of conventional fertilizer.
Nicolas Pinkowski
Nicolas Pinkowski is the Co-Founder and CEO of Nitricity, a Fremont, California-based clean energy company reinventing how nitrogen fertilizer is made. Armed with a Stanford PhD in Energy Systems, Pinkowski and his co-founders turned a backyard experiment on a lemon tree into a $95M-funded company producing organic nitrogen fertilizer from air, water, renewable electricity, and recycled almond shells. Their flagship product, Ash Tea, delivers 92% lower emissions than conventional fertilizers, has achieved OMRI certification, and has already generated over $150M in binding offtake agreements. Pinkowski was named to the Forbes 30 Under 30 list in 2021 and is an Unreasonable Food Fellow (2024), leading Nitricity's expansion from California into global markets.
