Zink
CEO: Wendy Caswell
Disruption: Inkless printing
Disrupted: Desktop printers, ink cartridge resellers, and photo services

Hate dealing with empty printer cartridges? You're the customer Zink is after. The Polaroid spinoff's special paper is embedded with dye crystals, so it can create color photos without the ink. As a result, its printers can be small enough to fit in your pocket. This holiday season, Zink's partners will begin selling the printers, including one that will be embedded in a digital camera.
