Windfall Bio Raises $28M Series A

Windfall Bio, a Menlo Park, CA-based company which specializes in methane-to-value solutions, raised $28M Series A funding.

The round led by Prelude Ventures with participation from Amazon’s Climate Pledge Fund, Global Brain (through its Norinchukin Innovation Fund L.P.), Incite Ventures, Positive Ventures and existing investors including B37 Ventures, Breakthrough Energy Ventures, Mayfield, and UNTITLED (a fund backed by the Tetra Laval family).

The company intends to use the funds to expand pilot deployments across methane intensive industries including agriculture, oil and gas, and waste management, and to continue building out its team, manufacturing capacity and supply chain.

Led by CEO Josh Silverman, Windfall provides a nature-based solution that leverages methane-eating microbes—referred to as mems—that capture methane from any source while also capturing nitrogen from the air to produce organic fertilizer on customers’ sites. For agriculture and industrial customers, mems create value by improving soil health, enabling emissions tracking and reporting, improving resource efficiency, and generating new revenue streams from the sale of organic fertilizer.
