“And Tristan Walker, director of business development, hounded Crowley daily via e-mail for a job in the summer of 2009. Here’s how that story played out, according to a Foursquare rep: “Finally, Dennis asked him if he was ever in NYC so he could come in for a meeting — Tristan told him he’d be in NYC that weekend and booked a flight that night. When he came in to meet with Dennis, Tristan told Dennis he’d sign up 100 local businesses in a month and shared some of his ideas for working with larger partners and redefining loyalty. He hit 100 businesses in a couple of weeks, and by month’s end he’d signed up 250 businesses and Dennis agreed to give him a job as Foursquare’s first business development employee.” Play is built-in to the work experience, naturally. Selvadurai speaks of a passionate group of team members who work hard and play hard. “Everyone’s extremely excited about all of the stuff we’re building and being surrounded by that type of energy is addictive,” he says.”
