Overflow is a United States-based financial technology company that provides a digital giving platform for churches, nonprofits, and other mission-driven organizations. Founded in 2020, the company offers tools for accepting cash and non-cash donations, including credit and debit cards, automated clearing house (ACH) transfers, stock donations, donor-advised funds (DAFs), cryptocurrency (discontinued by some partners), Apple Pay, Google Pay, and micro-donations through RoundUps™.[1]

History

edit

Overflow launched in 2020 with stock donations as its primary differentiator.[1] In 2022, it added cryptocurrency giving through an integration with The Giving Block.[2] The company later expanded into donor-advised fund giving in 2023 in partnership with Chariot.[3]

In October 2023, Overflow launched Overflow Tap, an NFC-based system allowing donors to give or access other engagement content by tapping their phone on a physical device.[4] Apple Pay and Google Pay support were added in October 2024, and RoundUps™ micro-donations were introduced in August 2024.[5] On May 20, 2025, Overflow introduced Overflow AI, a conversational assistant for analyzing giving data.[6]

Digital giving platform

edit

Overflow’s platform integrates multiple giving methods into a single interface, including credit and debit cards, ACH, stock, cryptocurrency, DAFs, Apple Pay, Google Pay, and RoundUps™.[1]

Overflow Tap

edit

Overflow Tap is a hardware and software solution using near-field communication (NFC) technology to enable “tap to give” functionality. The system supports various form factors such as discs, stands, lanyards, bracelets, and adhesive plates, and can direct users to donation pages, registration forms, or other digital resources without requiring an app or login.[7]

Overflow AI

edit

Introduced in 2025, Overflow AI is a conversational analytics tool embedded in the Overflow dashboard. It allows organizations to query giving data in natural language and receive visualized results, with planned future capabilities for forecasting and strategic planning.[8]

Generosity University

edit

Generosity University is an eight-lesson financial literacy course grounded in principles of stewardship. Topics include giving, budgeting, debt management, and investments. It is offered as small-group curriculum or staff training.[9]

Partnerships

edit

The Wikimedia Foundation, which operates Wikipedia, uses Overflow to process stock donations.[10] Wikimedia previously accepted cryptocurrency donations via other providers but discontinued this in 2022.[11]
