The Gentleman Agreement

The Gentleman Agreement was built for a problem a skating school kept having: waivers signed by whoever happened to be holding the phone. A parent's name typed into a box is not a parent's consent, and nobody finds that out until it matters.

So we built the check into the ceremony rather than beside it. The company is small and the platform runs entirely on AWS, in Canada and the United States, with no office in the middle of it holding a database of faces.
