This Thursday, San Francisco startups will participate in a charity pushup competition at the Minna Gallery, with all ticket proceeds benefiting five different charities. The participating companies include 99Designs, GitHub, Hotel Tonight, Udemy, and Zaarly. Each company has chosen to support one specific charity, including DonorsChoose, which connects donors with classrooms in need of financial support. The event aims to raise funds for these organizations and invites attendees to cheer on the teams and sponsor their favorites.
