Fundraise Up

AI-optimized donation checkout for nonprofits that personalizes ask amounts, payment methods, and follow-ups to lift conversion.

Fundraise Up was founded in 2017 by Peter Byrnes, Yuriy Smirnov, and Anton Isaykin and is based in New York City. The company built an embeddable donation checkout that nonprofits drop onto their existing website, replacing slower, form-heavy donation pages with a faster flow that adapts payment methods, suggested amounts, and messaging to each visitor. Rather than charging a monthly software fee, Fundraise Up takes a percentage of each transaction — up to 4% for card donations — and reports that the large majority of donors voluntarily cover that fee themselves, so most of its nonprofit customers pay close to nothing out of pocket. Customers include UNICEF USA, the Salvation Army UK, and the American Heart Association. The company raised a $70 million growth round led by Summit Partners in early 2025, bringing total funding to roughly $82 million.
