Enjoy this six-minute talk with Robert Kalin, the 26-year-old founder of Etsy. Kalin talks about how he’s grown the person-to-person ecommerce business despite competing directly with eBay. Etsy focuses on hand made items, and has a rabidly passionate community of buyers and sellers (also, 97% of Etsy users are women). Kalin also eats his own dog food – most of his clothing was purchased from the site, he says in the interview.
