Andreessen Horowitz operating partner Margit Wennmachers shares the founding story of OutCast, the PR agency she co-founded (acquired in 2005); her history as one of its first operating partners at a16z (and what makes it different); and her “golden rules” — and common pitfalls — for founders and entrepreneurs to know when it comes to branding and marketing technology startups.

This fireside chat with Jo White (who leads global comms at CookPad) originally took place at Startup Grind Europe 2018 in London, UK.
