The fund targets early-to-growth-stage companies developing solutions in medical devices, diagnostics, biopharmaceuticals, clean energy, water, food, and waste reduction, with the mission to 'invest in what the world needs.' The team leads early financing rounds, aims to be active board members, and deploys $15M–$20M per company, building companies with patient capital and prioritizing what is best for portfolio companies as the path to the best outcomes for investors.
