Jack Dorsey’s advice to startup founders: edit the team and really focus on analytics Jack shares that one of his biggest mistakes at Twitter was not editing the team: “I think for all startups it’s really easy to consider any hire as [part of the team for] the length of the entire company… [But] I think leaders of companies have to consider themselves editors, and you have to edit the team. You constantly have to make sure that you have the best people in, and if there’s any negative attribute within the team, you have to part ways.” Jack’s other piece of advice for entrepreneurs or anyone starting a project is to really focus on analytics: “Really focus on how people are using the system… You need to have an understanding of the momentum of what you’re doing and where you’re going. And you can only do that with data.” Data should inform everything from product decisions to communication with your customers to hiring and editing the team. Video source: @kevinrose (2010)
