Andreessen Horowitz (a16z) partner Katie Haun, a prominent name in crypto investing, is leaving after four years to start her own firm.

Axios broke the news, and the fact that she will be joined by a small number of a16z staffers, including crypto marketing head and Coinbase alum Rachael Horwitz but no one from the investing team.

Haun, a Coinbase director and former U.S. prosecutor, has helped a16z become crypto’s most well-known backer. Earlier this year, a16z raised $2.2 billion for its third crypto fund and has already deployed a bevy of investments.

“Today [Chris Dixon] and I shared with the a16z crypto team that I will be launching my own fund focused on crypto and Web 3 early next year. The current crypto fund will be my last at the firm,” Haun said on Twitter.

“When Chris and I started our first crypto fund in 2018, it was a moonshot experiment. Thanks to the hard work of many, it has exceeded both of our wildest expectations. Today it’s more apparent than ever that [Web 3] will transform the internet,” she added.

A16z said in an emailed statement that Haun “led some of the most consequential crypto team deals including Coinbase, OpenSea (Series A and B), Celo, Arweave, and Royal.”

She will retain her board seats at Coinbase and OpenSea.
