Elizabeth Yin and Eric Bahn, former partners with 500 Startups, are seeking to raise $50 million for Hustle Fund I, according to a regulatory filing. The fund has not yet raised any commitments. Information about the Hustle Fund, which lists an address in San Carlos, California, is not available. But in a blog post earlier this, Yin described how today’s crop of new VCs work hard to find deals and “They have to hustle for every deal. They have to hustle to fundraise for their current or next fund.”

Yin, who previous co-founded adtech company LaunchBit (acquired by BuySellAds in 2014), joined the 500 investment team in 2015 to run the program’s Mountain View, California-based accelerator. She resigned in the summer over the way the organization handled the sexual misconduct allegations toward co-founder Dave McClure, who has since resigned.
