What Overflow does
Overflow is a Palo Alto-based fintech company that operates a unified digital giving and engagement platform for churches and nonprofit organizations. The platform accepts donations across multiple asset classes — credit/debit cards, ACH, Apple Pay, Google Pay, publicly-traded stock, cryptocurrency, Donor-Advised Funds, and RoundUps micro-donations — and is differentiated by support for non-cash giving with no transaction caps and by the proprietary Overflow Tap NFC technology for in-person engagement, which the company claims is materially more effective than QR codes. Customers manage the full stack through an organization dashboard, and the product is distributed under the sub-brands Overflow Giving, Overflow Tap, ExpressGive, and the educational Generosity University.
The business model combines subscription pricing for the giving platform, per-transaction processing fees on donations, and one-time hardware sales of Tap devices in multiple form factors (discs, plates, labels, stands, lanyards, bracelets, wristbands, magnets). Go-to-market is direct sales with 15-minute demo calls, complemented by event-driven demand generation at church and ministry conferences, content marketing, SEO, and an integration ecosystem spanning Planning Center, Rock RMS, Salesforce, PushPay, MinistryPlatform, Virtuous, ProPresenter, Zapier, QuickBooks, and Chariot for DAF rails. Customers include over 1,000 ministries and organizations globally, with named accounts spanning large churches (Church of the Highlands, Highlands College, Life Church, VOUS Church, Highpoint Church) and major nonprofits (Wikipedia, World Wildlife Fund, American Cancer Society, Convoy of Hope, Warriors Community Foundation).
Overflow is privately held, incorporated in California as Overflow App Inc., with 51-100 employees. It has raised approximately $30M+ across disclosed funding rounds including a $10M Series A in October 2021 and a $20M round in February 2024, with investors including R7 Partners, Salesforce Ventures, Uncork Capital, Craft Ventures, Able Partners, Village Global, Wesleyan Investment Foundation, and The General Partnership. In June 2024 the company acquired Novity to bring NFC tap technology in-house, and has since expanded the platform with DAF giving, on-demand donor statements, and a ProPresenter integration for Overflow Tap.

Overflow competitors and assessment
Company assessmentOthers
- Chariot: Chariot is a payment network connecting Donor-Advised Fund providers and is Overflow's partner for three-click DAF giving. It is an ecosystem enabler rather than a competitor, but its direct DAF integrations are strategically important to Overflow's non-cash giving moat.
Direct peers
- Pushpay: Pushpay is the largest dedicated church giving and engagement platform in North America, directly competing with Overflow on digital tithing, mobile giving, and church management. Overflow's VP of Payments was hired from Pushpay, underscoring the head-to-head competitive overlap.
- Tithe.ly: Tithe.ly is a church giving and engagement platform offering mobile tithing, text-to-give, and church management software. It overlaps with Overflow's core Giving platform and Tap-style engagement use cases for churches of all sizes.
- Subsplash: Subsplash provides churches with giving, apps, websites, and media tools. It competes with Overflow on digital giving and broader church engagement, especially for mid-sized and large churches seeking unified software platforms.
- Donorbox: Donorbox is a recurring donation platform built primarily for nonprofits, supporting online donations, crowdfunding, and events. It overlaps with Overflow's nonprofit segment and shares a similar transaction-fee plus subscription model.
Broad incumbents
- Planning Center: Planning Center is a leading church management suite that includes giving functionality alongside check-ins, registrations, and people management. Overflow integrates with Planning Center but also competes with it where churches consolidate giving into their ChMS.
- Network for Good: Network for Good is an established nonprofit fundraising and donor management platform offering online giving, CRM, and event tools. It competes with Overflow in the broader nonprofit donation platform category, particularly with smaller and mid-sized organizations.
- Blackbaud: Blackbaud is a large, established provider of fundraising, CRM, and financial software for nonprofits and educational institutions. Its broader portfolio overlaps with Overflow's nonprofit segment, especially for larger institutions seeking enterprise-grade donor stewardship.
- Stripe: Stripe provides the underlying payment infrastructure that many giving platforms (including Overflow's competitors) build on. While not a direct competitor at the church level, Stripe's expanding fintech stack — including crypto and DAF-style products — represents an indirect competitive and partnership vector.
Emerging players
- Givebutter: Givebutter is a modern fundraising platform for nonprofits supporting online donations, events, auctions, and DAF giving. It increasingly competes with Overflow on the nonprofit side and on newer giving methods such as DAFs and crypto.
