Seattle-based ImageKind, which launched this morning, is a service for creating, buying and selling wall art. The company was incubated at Curious Office Partners and built in six months for less than $300,000. But unlike Cafepress, Zazzle, Spreadshirt, innerTee and the rest, this isn’t about printing tees, mugs and mousepads - ImageKind supplies user-generated artworks printed on paper and canvas. They also provide framing and related services.
