Secret, the app that lets users share notes with others without revealing their identity, has attracted a lot of controversy (or celebration, depending on who you are) for how it enables the spread of racy but sometimes mean or simply controversial notes about people, places and things. But it is also attracting a lot of something else: moolah. Today, the startup co-founded by ex-Googlers Chrys Bader-Wechseler and David Byttow has announced that it has raised another $25 million in funding. The Series B round includes Index Ventures, Redpoint Ventures, Garry Tan and Alexis Ohanian, SV Angel, Fuel Capital, Ceyuan Ventures, and — fittingly — “several others that shall remain a secret.” Index’s Danny Rimer is joining the startup’s board of directors. The company has now raised just over $36 million, with other investors including Google Ventures, Joe Montana, Kleiner Perkins, David Sacks and many more. The NYT notes that this latest round values the company at over $100 million.
