“Given Mozilla’s small initial size, this growth necessitated hiring executives from the outside (“the graft”), which was particularly challenging because of the company’s strong engineering-driven culture (“the host”) that was already skeptical about outsiders. John was able to do this successfully by following the same three-step process that was used to hire him. Hire someone who is already a known quantity to at least one member of the team. John was hired by Mitchell Baker, his predecessor as CEO of Mozilla. The two had gotten to know each other by serving on a board together, and Mitchell’s personal endorsement of John carried weight with the team at Mozilla.”
