We tell founders not to hire $100,000 agencies because the best messaging comes from the founders themselves. But for that to happen, they need access to experts for strategy, feedback, and guidance. That’s what we bring to your portfolio.

Who we are

Experts who led communications, social, events, and community at Y Combinator and Andreessen Horowitz—and advised thousands of founders who went on to create billions in market value.
