At WeightWatchers (WW), I led the design of the Challenges & Badges experience—a project aimed at motivating members and enhancing accountability without relying on real-world currency. This initiative resulted in over 2 million sign-ups within the first eight weeks and increased tracking behaviors by 16%.

Summary

Over 2 million Challenge sign-ups in the first 8 weeks, boosting tracking behavior by 16%.

Potential savings of $8.2 million annually by reducing reliance on costly rewards programs.

A/B testing revealed a 9.3% increase in weekend tracking and a 12% decrease in cancellations.

Achieved 1.5 million Challenge opt-ins within 7 weeks of launch; 12% completion rate and 22% re-engagement rate.
