In technology circles, people talk about the merits of eating your own dog food  making sure your company is actually using the same products or services it is selling.

Etsy, an independent online marketplace for handmade products and vintage goods, is getting its fair share of dog food.

Most everything in the company’s sprawling offices in the Dumbo neighborhood of Brooklyn is from sellers on Etsy.com, from the long panels of gingham curtains covering the windows to the mismatched desks and work tables. An elaborate chandelier and a pair of six-foot-long wooden eyeglasses rest in the middle of one room; a rowboat is perched in the opposite corner.

Since it was founded in 2005 as a way for hobbyists and crafty types to sell their goods, Etsy has blossomed into a thriving e-commerce site and one of New York’s hottest start-ups. The company says it expects to bring in $30 million to $50 million in revenue this year and has been profitable for a year. It has seven million registered users, nearly twice what it had a year ago.
