Built inside a school.

I'm Isaac Johnston. I built FillMyClass while working in an elementary school. I saw my fellow colleagues stress over finding substitute coverage.

The school didn't lack substitutes. They lacked an easy way to reach all of them at once. That gap seemed too small to deserve district-scale software and too painful to keep ignoring. So I built the tool our school needed. I knew we weren't the only school facing this problem, so I designed it with other schools in mind as well.

FillMyClass is that tool, grown up: teachers request coverage in seconds, the school's own sub pool is notified at once, and the sub can accept or decline the request.
