C-Combinator, with a $29 million valuation cap, is raising crowdfunding on Wefunder. The company is delivering market-based solutions to climate issues by taking the largest seaweed bloom and turn it into high-value products. The technology helps in protecting the climate and enhancing biodiversity in soils and seas. Ben Ellis and Geoffrey Chapin founded C-Combinator in January 2020. The proceeds of the current crowdfunding round, with a minimum goal of $100,000 and a maximum goal of $1,070,000, will be used towards purchasing a filtration system and operational expenses. C-Combinator creates a biostimulant that increases crop yields by 15-40% and prevents seaweed from rotting and emitting methane.
