FORTUNE — Nikhil Kalghatgi has spent the last three years investing in early stage startups at Softbank Capital. Earlier this year he left that role to launch his own fund.
Vast Ventures, which describes itself as an early stage venture fund, is in the midst of raising a $50 million investment vehicle, according to an SEC filing. The filing was posted in January.

Kalghatgi is listed as a managing partner at Vast Ventures. His partner is Doug Chertok, who is also an adviser to venture firm Dace Capital. Vast Ventures’ website showcases a large portfolio, with companies like ZocDoc, Fab, Meetup, Sidecar, Klout, and Soma, the charitable water filter company. The portfolio is likely from prior Vast Ventures vehicles, which Kalghatgi and Chertok worked together on informally.
Kalghatgi declined to comment, citing SEC regulation around fundraising.
