Mike Volpi of Index Ventures started investing in open-source software companies when it wasn't clear if they could make much money. This past week — more than any before it — has validated his conviction that they can.

On Wednesday, Hortonworks, a big-data software company backed by Volpi, announced that it was merging with competitor Cloudera. Two days later, another one of Volpi's companies, Elastic, started trading on the New York Stock Exchange and doubled in value in its debut.
