Double

Double is a fundraising optimization platform designed to help nonprofits generate more revenue from their donation campaigns while improving the donor experience. Its tools focus on the full giving journey: reducing friction in donation forms to help supporters complete gifts, using personalized suggested amounts to increase average donations, and offering one-time donors a path to become monthly supporters. Double also helps organizations retain recurring donors by automatically retrying failed payments and re-engaging supporters when payment details need attention.

The platform is intended for organizations that view fundraising as a significant source of revenue and want measurable improvements in conversion, gift size, recurring income, and donor retention. Double’s website highlights ease of implementation, responsive customer service, and ongoing product development, alongside support for discussing ideas and suggesting features. Nonprofits can book a demo to explore the service. By addressing abandoned donations, missed opportunities to encourage larger or recurring gifts, and payment-related donor lapses, Double aims to improve the performance of each fundraising moment and sustain giving over time.
