Floodgate is a Silicon Valley venture capital firm founded in 2006 by Mike Maples Jr. and Ann Miura-Ko, originally operating as Maples Investments before rebranding to Floodgate Fund in March 2010. The firm pioneered the micro-VC model, focusing exclusively on early-stage technology startups at the pre-seed and seed stages, primarily in sectors like AI, enterprise software, healthcare, fintech, consumer tech, and crypto. Floodgate typically invests between $150,000 and $1 million per company and often leads or co-leads seed rounds to set terms rather than just follow on. Notable portfolio companies include Twitter, Lyft, Twitch, and Okta, all backed early before achieving massive market traction. A distinctive point of view is Maples’ “Inflection Theory,” which identifies “Prime Movers”—founders navigating major technological or market shifts—as the firm’s ideal investment target. Floodgate also promotes the “Thunder Lizards” concept, describing companies with potential to become wildly disruptive market leaders.
