Givebutter

Givebutter completely disrupted the massive non-profit software industry by offering an incredibly powerful, all-in-one fundraising CRM and auction platform completely for free. Instead of charging the non-profit a massive SaaS subscription, Givebutter relies on "Optional Donor Tips." When a donor checks out, the software asks if they would like to add a small tip to cover the platform's operating costs. Because of this model, their Auction software is heavily utilized by modern, digitally native charities that refuse to pay enterprise software fees. The auction module is built seamlessly into their broader fundraising suite. A user can run a peer-to-peer walkathon, sell tickets to a gala, and run a mobile silent auction all from the exact same dashboard, with all the data flowing perfectly into the free Givebutter CRM. The interface is incredibly modern, colorful, and heavily inspired by social platforms like Venmo and Kickstarter. During a live auction or a telethon, Givebutter provides a "Supporter Feed"—a live, scrolling wall on the projector showing the names of people who just bid, complete with animated GIFs and emojis, driving massive social proof and encouraging other people in the room to donate.
