Sarah Clark is the Chief Marketing Officer of Rapha, the British cycling brand known and loved for celebrating cycling as a sport and culture. Rapha is a prime example of how a brand can build an authentic community around a clear purpose: it runs its own cycling club with thousands of members, operates 22 clubhouses around the world, organizes weekly rides that anyone can join, produces movies, has a beautiful print magazine and a ton of other projects that help people discover their passion for cycling. I met Sarah at Rapha's London headquarters to find out how it all came about: how Rapha got started, how her vision of the brand evolved and Sarah's advice for people who want to start their own mission-driven brand.
