Stratify is an "eDiscovery" product that was just picked up by Iron Mountain for a cool $158 MM. Bill Burnham, one of the early stage investors, tells the story of how the company endured numerous rounds of fundings, restructurings and business model changes:
The reality was that they had a fantastic product in what was effectively a very small market. Everyone put their heads together to try and figure out how to build the business faster, but in many ways the company was stuck. And then something totally unexpected and very fortuitous happened: I got sued.
Fascinating read. Reminds me of what Marc Andreessen says about product/market fit.
