Overflow

Overflow is a faith-driven fintech company that builds digital giving software for churches and nonprofits. Founded by pastors, the firm has set itself the mission to "inspire the world to give", and its Overflow Giving Platform collects cash and non-cash donations - stock, cryptocurrency, Donor-Advised Funds, Apple Pay and Google Pay - alongside a RoundUps feature that rounds up donor transactions, all within a single giving flow. AI-powered insights are embedded in the product to help organisations maximise giving. The platform is trusted by more than 1,000 ministries and organisations.

The company reports measurable results for the churches it serves: increases of up to 800% in prayer requests and 150% in online giving. Technical work spans fintech, digital payments, non-cash asset donation processing and platform and product design, with an stated emphasis on beautiful design, speed, flexibility and ease. Overflow is backed by investors including Uncork Capital, Craft Ventures and Village Global.

Overflow operates from offices in Los Gatos, California and Birmingham, Alabama, and offers a flexible work model. The company's stated culture combines a faith-based mission with product-led engineering across payments and giving infrastructure.
