Giveffect

Giveffect is an all-in-one nonprofit management platform that combines ten seamlessly connected systems into a single suite for charitable organizations: constituent relationship management (CRM), online fundraising and donation processing, peer-to-peer and event fundraising, volunteer management, membership management, email and marketing communications, wealth screening and major-gifts tools, website building, and smart automation and workflows. Giveffect exposes an optional "open API" on its enterprise (Ultimate+) tier for integrating the platform's donor, donation, volunteer, and campaign data with external systems, and ships prebuilt integrations with QuickBooks Online, DonorSearch, Double the Donation, Zoom, The Giving Block, and Ez Scan. The company was surfaced as a Y Combinator portfolio company and enriched into the API Evangelist network.
