Overflow

Overflow is a faith-and-nonprofit fintech that lets churches, ministries, universities and charities accept the kinds of gifts most donation tools ignore - publicly traded stock, cryptocurrency, donor-advised funds, ACH, cards and digital wallets - all through one online flow that replaces the old fax-and-paperwork process for asset-based giving. Founded by former Google engineer Vance Roush after his own church struggled to accept stock gifts, the company reports that donors who give appreciated assets tend to give far more than they would in cash, and it has expanded into NFC 'Tap' giving hardware, an AI-assisted giving product and analytics. Overflow raised a $20M Series B in February 2024 and says it serves more than 1,000 organizations.
