Powerpoint presentation sharer SlideShare has raised a $3 million first-round investment. David Siminoff, a partner with lead investor Venrock, is joining a board that includes Guy Kawasaki, Marc Cuban, Ross Mayfield and Saul Klein. With bases in San Francisco and New Delhi, the company claims over 300,000 presentations have been added since its 2007 launch and, rather optimistically, aims to host “every presentation in the world”. SlideShare offers document embedding, includes social features like “most viewed” and also supports PDF and OpenOffice docs. But it’s competing variously with the likes of Scribd, Slide, SplashCast, Preezo, SlideBoom, Google (NSDQ: GOOG) Docs and tools like iSpring. The race may be on to be the YouTube of presentations - but the contenders are riding the wave against PowerPoint ennui. Release.
