VC-backed Crocodoc, an HTML5 document rendering and viewing company, has been acquired by Box, also VC-backed. Crocodoc's technology brings HTML5 document viewing to third party applications across the web and mobile devices. A Y Combinator grad, it took in an angel round of funding from XG Ventures and several individual backers in 2010. It heads now to Box, a content sharing platform backed by the likes of Intel Capital, New Enterprise Associates and Andreessen Horowitz.
