When Josh Silverman started shopping around the idea for his methane-eating microbe startup, Windfall Bio, eight years ago, the market just wasn’t ready. Menlo Park–based Windfall Bio raised a $28 million Series A round to expand its commercialization efforts. The round was led by Prelude Ventures with participation from Amazon’s Climate Pledge Fund, Incite Ventures and Positive Ventures, among others, as well as existing investors, including Mayfield. Windfall works with industries that produce large levels of methane, such as agriculture, oil and gas, and landfills. The startup supplies methane-eating microbes that absorb methane emissions, turning them into fertilizer.
