Overflow

Donations platform for stocks and crypto

Overview

Overflow helps churches and nonprofits accept and manage donations of non-cash assets like stocks and cryptocurrency, alongside cash gifts, through a subscription-based financial technology platform. Donors can give via multiple channels (card, ACH, stock, crypto, and donor-advised funds), and Overflow processes these gifts while providing automated giving statements, live dashboards, and detailed donor and gift-status tracking. The platform focuses on reducing barriers to giving and offering low processing fees, aiming to stand out with a comprehensive, end-to-end solution for charitable fundraising. Overflow’s goal is to make generosity frictionless and to significantly increase charitable contributions by unlocking and simplifying the use of non-cash wealth, which makes up a large portion of global assets.

Simplify's Take

What believers are saying

  • Overflow's 2026 ExpressGive generated 53 first-time givers for Access Church.
  • Valley Rise Church reported 58.5% giving growth over twelve months using Overflow.
  • Overflow's 2026 case studies show repeatable expansion across stock, crypto, and mobile giving.

What critics are saying

  • The Giving Block integration reduces Overflow's crypto exclusivity and weakens product lock-in.
  • Church giving concentration ties revenue to faith-sector budgets and adoption cycles.
  • If stock-giving volume stalls, subscription fees alone won't justify a venture-scale outcome.

What makes Overflow unique

  • Overflow bundles cash, stock, crypto, DAFs, and tap-to-give for churches.
  • Wesleyan Investment Foundation led Overflow's $20M Series B on 2024-02-08.
  • Overflow claims first Church-built digital giving stack, with analytics, migration, and donor support.
