Amy Wu, a former partner at Lightspeed Venture Partners that joined FTX in January to launch a $2 billion venture fund, resigned on Thursday, after the Lehman Brothers–style collapse of the crypto exchange this week left its VC arm in shambles.

Wu, who confirmed her resignation with The Information, was an early advocate of Web3 startups, investing in Ethereum startup Offchain Labs and blockchain gaming company Faraway while a partner at Lightspeed. At FTX, Wu led a team of investors that struck deals with roughly 50 crypto startups this year, including Mysten Labs and Helium, the company behind the Helium blockchain network.
