Santa Monica-based ZipRecruiter, a new startup focused on the online job board market, said that it has launched its service this week. The startup, whose founders have served at such firms as CitySearch, Stamps.com, Rent.com, and ThisNext, said it provides a service which allows users to post to multiple, free job boards with one submission. The site had been running in a closed beta for the last three months. The new company was founded by Ian Siegel (CitySearch, Stamps.com, Rent.com, and Pictage); Ward Poulos (Rent.com, Just Fine, Pictage, MyLife.com); Will Redd (Rent.com, ThisNext.com, Sony, GE, Maytag); and Joe Edmonds (Stamps.com, Rent.com, ThisNext.com).
