Floodgate: The Seed-Stage 'Super Angel' Behind Twitter, Lyft and Twitch

Floodgate, the Menlo Park seed-stage firm, calls itself "Your First True Believers" — and few taglines in venture capital have been earned as thoroughly. Founded by Mike Maples Jr. and Ann Miura-Ko, Floodgate was among the first of Silicon Valley's "super angel" firms: writing tiny first cheques into companies the rest of the market had not yet noticed, then riding them to world-changing scale. Its early bets include Twitter, Lyft, Twitch, Chegg, TaskRabbit, Okta and Rappi.

The firm’s philosophy comes straight from Maples. He describes Floodgate’s ideal investment as a "Thunder Lizard" — a startup that takes a tiny amount of seed funding and grows into a world-changing success (VentureBeat, 2010). The accompanying doctrine is "pattern breaking": backing non-consensus founders at the moment when the evidence is thinnest and the upside is largest.

Floodgate invests at seed and very early stages in technology companies, historically across the San Francisco Bay Area and Austin, Texas (TechCrunch, 2017). The firm has never chased stage creep; its edge is conviction at the earliest point of a company's life, when a cheque is small but the relationship compounds. That focus shows in its portfolio construction: a concentrated set of first-cheque bets rather than a spray of options.

On fund size, Floodgate is unusually discreet. The last publicly confirmed figure is Fund VI, a $131 million vehicle closed in March 2017 and disclosed via an SEC filing reported by TechCrunch. As TechCrunch noted at the time, Floodgate "doesn't typically make announcements around its fundraises" — later fund sizes have appeared in third-party databases but could not be verified from a primary source, so this profile states only what is confirmed.

The portfolio beyond the headline names is instructive. Demandforce, a marketing software company, was acquired by Intuit for around $420 million; Xamarin, the mobile development platform, was acquired by Microsoft. Both were the kind of unglamorous-at-first technology bets the Thunder Lizard thesis favours: deeply technical products, early revenue signals, and founders building before a category had a name.

Leadership remains founder-led: Mike Maples Jr. serves as managing partner and Ann Miura-Ko is a co-founding partner. The partnership is deliberately small, consistent with a strategy built on a handful of high-conviction decisions per year rather than institutional scale.

Floodgate runs no accelerator, fellowship or founder programme of its own. Maples hosts the "Starting Greatness" podcast, but that is a personal project rather than a firm-run initiative — founders should not expect a formal platform of perks or credits from the firm. The value proposition is simpler: an early believer with a record of being right about non-consensus bets, and a network built over two decades at the top of seed investing.

For founders, the practical read is straightforward. Floodgate is not a fit for consensus ideas with obvious traction — by the time the market agrees, the firm has usually moved on. It suits technical or contrarian founders who can articulate why the world is wrong about their market. Indian founders should note the firm has no India presence and is centred on the Bay Area and Austin — but Maples’s writing on pattern-breaking remains among the most useful free fundraising education available.
