“Can a thin SaaS layer on top of Stripe and PayPal become the default operating system for small-to-mid-sized nonprofit fundraising worldwide?”
Donorbox began in 2014 as a free WordPress plug-in that let nonprofits accept online donations via Stripe and PayPal. Rather than becoming a merchant of record, it has stayed resolutely in the SaaS/software layer — nonprofits bring their own Stripe or PayPal account, and Donorbox earns a platform fee on top. The company has expanded horizontally into donor CRM (Jay·AI), event ticketing, peer-to-peer, kiosk hardware (Donorbox Live™), text-to-give, memberships, and most recently stablecoin and BNPL donation methods — becoming a full fundraising OS for the ~100,000 nonprofits it serves while keeping payment risk and compliance on Stripe/PayPal.
Donorbox processes payments through Stripe and PayPal. Disclosed money-movement rails: ACH and SEPA.
Donorbox's lending and capital products are provided by Afterpay and Klarna.
Donorbox integrates with QuickBooks.
The Embedded Finance Index 2026 maps 4 layers in Donorbox's stack: Payments / PSP (Stripe and PayPal); Money movement (ACH and SEPA); Lending (Afterpay and Klarna); Accounting (QuickBooks).
Donorbox was founded by Charles Zhang and is founded in 2014, headquartered in Alexandria, Virginia, United States (with office in San Francisco).
