Duration Ventures, Founded by Alumni of GC and Lightspeed, Aims for $375 Million Fund

Duration Ventures, a new venture firm founded by former General Catalyst and Lightspeed investors, is seeking about $375 million for its debut fund, according to a report published Monday by The Wall Street Journal.

The firm was launched by Arif Janmohamed and Trevor Oelschig. WSJ reported that the fund will focus on early-stage enterprise artificial intelligence, from chips to applications.

Janmohamed separately posted on LinkedIn that he is starting a new early-stage venture firm while remaining a venture partner at Lightspeed. That post provides public confirmation of the move, though the current reporting does not say whether Duration Ventures has completed any first close or secured publicly disclosed limited partners.

The launch comes at a time when fundraising remains difficult for many emerging managers, making the size of the target notable for a first fund.

What happens next

Public reporting has not yet identified formal fundraising filings, a first close or additional partners beyond Janmohamed and Oelschig. Further disclosures would likely clarify the firm’s pace of fundraising and the scope of its investment strategy.
