Tumblr founder is happy he sold the website to Yahoo

It’s been almost one year since Yahoo announced that it had acquired Tumblr for $1.1 billion, and David Karp, founder and head of Tumblr, says that its new owner has “lived up to everything they promised.” Speaking in an interview with the New York Times, Karp said that Yahoo and its CEO Marissa Meyer have supported his business with additional resources — Tumblr’s roster has more than doubled to 220 staff — and have remained hands off. “We’re our own shop. We have our own leadership, and we’re doing things our own way,” Karp said.
