Widget Maker Slide Raises $50 Million Fourth Round From Wall St.

Slide, the maker of social networking widgets, has raised a big $50 million fourth round from Fidelity and T-Rowe Price. The round, sans-dollar amount, was first reported by Kara at All Things D; Brad Stone at Bits then reported the amount. The Silicon Valley-based company founded by PayPal’s Max Levchin has raised three unspecified rounds, with the last one coming in late 2006. The latest values the company at an impressive $550 million, a price tag that should embolden other investors and startups that piggyback on social networking services. Originally, Slide started by offering a tool for online slideshows, but it has since introduced a range of widgets that work on various social networks. The company now has 64 employees, a number it plans to add to with the latest round. The company is frequently described as a competitor to RockYou, another funded maker of popular social net widgets.
