Fill In is a last-minute fitness marketplace that connects busy professionals with open spots at boutique studios in real time. Instead of forcing people to plan their day around a workout class, Fill In helps classes fit seamlessly into the day they are already having.

For studios, Fill In is a modern marketing engine. When a class has empty spots, studios can instantly push discounted or special-offer classes to nearby users based on real-time location and timing, turning what would have been lost revenue into full classes and new loyal members.

For members, Fill In makes it effortless to stay active. Users receive smart notifications for nearby classes that match their schedule, location, and preferences, so they can “fill in” pockets of free time with high-quality workouts, whether that is during lunch, after work, or between meetings.

What we do:

Help boutique studios increase utilization and revenue from unsold spots

Deliver geo-targeted, real-time class notifications to nearby users

Provide busy professionals with flexible, last-minute fitness options

Turn local fitness discovery into a simple, mobile-first experience

Who we serve:

Boutique fitness studios and gyms
