Insight Partners principal Harley Miller is leaving the New York-based firm to launch a new fund, according to three people familiar with the matter.

Insight is a limited partner in the new fund, which is trying to raise around $600 million, the people said.

Miller, who joined Insight in 2010, is an early-stage investor in the German meal kit company HelloFresh, the fintech company N26, meditation app Calm, online learning platform Udemy, and French carpooling marketplace Blablacar.

In January, he led a $39 million Series B in the Farmer's Dog, a subscription service that makes personalized meals for dogs.

It's unclear what the focus of the new fund will be, though sources said Miller will likely keep doing early-stage investing.

Miller and Insight Partners did not respond to requests for comment.

Last June, Insight raised a $6.3 billion Fund X, with the majority of that capital coming directly from Insight's general partners.

The team put its capital to work last week with a massive $200 million Series A funding round for the privacy startup OneTrust. That round, led by Insight, valued the three-year-old company at $1.3 billion
