Some families have multiple children. Those kids are quite frequently of different ages, and thus will have entirely different activities (most high school football teams will not allow 5th graders to play, for example).

Those activities frequently overlap. No, Cub Scouts does not care that the high school basketball game overlaps with the camping trip because Cub Scouts are not in high school. Parents are (still) not able to be in two places at a time.

This means that at least some of the time, the older kid goes to their game without their parents. (Because the younger child frequently cannot.)

If you are able to solve this for those parents, you can be the first $1B single-employee company.
