If your church has ever turned away a stock donation because the paperwork was too complicated — or never even thought to ask for one — Overflow was built to solve that exact problem. This giving platform helps churches and nonprofits accept donations of stock, crypto, DAFs (donor-advised funds), and traditional card and ACH payments all in one place, making non-cash generosity as simple as tapping a phone.^1
Founded in 2019 by Vance Roush — a former Google product manager turned executive pastor at VIVE Church in Silicon Valley — Overflow started when members of his congregation wanted to donate tech stock but the process required physical forms and a fax machine. After building a solution that unlocked millions in stock gifts for his own church, Roush turned it into a platform now used by hundreds of churches and organizations, including Church of the Highlands, ZOE Church, Celebration Church, Change Church, and the Golden State Warriors Community Foundation.^2
Overflow has raised over $30 million in venture funding from investors including Salesforce Ventures, Uncork Capital, Craft Ventures, and the Wesleyan Investment Foundation.^4 Churches see an average 12% increase in giving after migrating, with an average stock donation roughly 100 times the national average cash gift. Key features include Overflow Tap (NFC-enabled physical products for contactless giving at services and events), ExpressGive™ (text-to-give in seconds), Overflow AI (analytics tool built specifically for church finance teams, launched May 2025), RoundUps™ (spare-change giving), and integrations with Planning Center, Rock RMS, Salesforce, and Zapier, plus a dedicated migration team that handles the switch from other platforms.^1 In August 2024, Overflow launched Generosity University, a discipleship program designed to cultivate a lifestyle of giving within church communities.^6
Roush also authored High Growth Fundraising the Silicon Valley Way, an Amazon Best Seller, and the company reserves 10% of its revenue for the Overflow Generosity Fund through the Overflow Foundation.^4
