 We&rsquo;re Fundraise Up - a global fundraising platform built to make donating to nonprofits fast, seamless, and accessible to all. Every month, our technology powers tens of millions of dollars in donations across the globe. We focus on innovation that directly impacts results: faster load times, higher conversion rates, global payment support, and accessibility-first design.

With a 4.9/5 rating across top software review platforms, we&rsquo;re recognized not just for our impact - but for the quality of the product we deliver.

 We operate in the enterprise segment, serving nonprofit organizations across North America, the United Kingdom, Australia, and Europe.
 
 
 We&rsquo;re building a
 
 large and complex product ecosystem
 
 that serves nonprofits, donors, and partners around the world. The platform includes a modern
 
 checkout experience and customizable widgets
 
 (each a standalone SPA),
 
 donor, organization, and partner portals
 
 ,
 
 admin tools
 
 , and several internal apps.
