Increase average gift size. Grow recurring revenue. Recover lost donations. Reduce donor churn.

Double improves the outcome of every fundraising moment by optimizing how supporters give and how long they stay.

Convert more donors before they leave

Double optimizes your donation flow in real time — removing friction, surfacing the right options, and guiding donors to complete their gift.

Increase average gift size intelligently

Smart, personalized suggested amounts based on donor behavior and capacity — so every ask is calibrated to get the most from each donor.

Turn one-time donors into recurring supporters

At the right moment, Double presents a seamless upgrade path — turning single gifts into monthly commitments that compound over time.
