Floodgate is a venture capital firm based in Menlo Park, California, founded in 2006 by Mike Maples Jr. and Ann Miura-Ko. Originally named Maples Investments, the firm rebranded to Floodgate Fund in March 2010.

Floodgate focuses on investing in early-stage technology companies, particularly in sectors such as business-to-business services, cryptocurrency, financial technology, healthcare, SaaS, and other technology domains. The firm is known for backing 'Prime Movers'—founders who possess the vision, talent, and determination to create significant impact from the ground up. Floodgate's investment philosophy centers on partnering with these exceptional founders at the inception of their journeys, even when their ideas challenge conventional wisdom.

The firm has a history of supporting companies that redefine industries and create enduring change. As of 2017, Floodgate's portfolio includes notable companies like Lyft, Refinery29, LabDoor, MissionU, TextIQ, Okta, and Rappi. The firm has also invested in Applied Intuition, a software company for autonomous vehicles.

Floodgate's approach is characterized by a willingness to embrace high-, high-reward opportunities, understanding that groundbreaking innovations often appear unconventional at first. This strategy has led to a diverse portfolio with successful exits and a reputation for identifying and nurturing transformative startups.
