What it is
A marketplace where schools and nonprofits list the gyms, fields and auditoriums they aren't using, and clubs and community groups find them, book them and pay online: search by location and type, see what's open, confirm without the phone tree. Carlos Rivera spent most of his career in tech, holds a master's in technology management from Columbia and sits on the Consultative Board at Sacred Heart High School in Los Angeles, so he has seen the empty gym from the school's side of the desk. Before Subler, he was the one leaving the voicemails; he started by managing rentals for three schools himself, then built the software.
Why it earns the pick
If your fall practice schedule depends on a facilities office that hasn't called back, this is the shortest route to a yes. Schools want the revenue, clubs want the room, and Subler is the first place both sides can see each other. His advice stands on its own, too: build the packet before you ask.
