Beyond the Tour

Monthly Donors That Stay

The real magic happens after the tour. Propeller converts one-time donors into monthly supporters who stay engaged year-round through exclusive content, actions, and rewards, building a sustainable revenue engine for The Upside Fund.

Exclusive Rewards

Monthly donors earn points redeemable for signed merch, exclusive content, and VIP experiences.

Actions & Engagement

Petitions, social shares, quizzes, and learn-and-earn modules keep donors active between campaigns.

Compounding Growth

Each tour adds new donors to the base. Retention stays above 95%, building a foundation that grows every year.

The program runs 24/7. No reliance on seasonal campaigns, no lapsed donors. Propeller helps generate a sustainable revenue engine that compounds month after month.

Let’s Turn Every Note Into Impact

Propeller is ready to build the always-on donation infrastructure, cruise flyaway sweepstakes, and in-venue activation system for The Upside Fund × Lindsey Stirling.
