World's Easiest Program Operations.
Assembly is your support staff and infrastructure. You run the programs, we run everything behind it: program setup, registrations, payments, and communication, fully handled by a dedicated team behind your programs, athletics, and events.

Trusted by schools & community organizations nationwide
The Only Activities Platform that gives you a team to run it for you.
From a single after-school club to a multi-site network, Assembly puts a dedicated Community Manager and program team behind your activities, replacing fragmented marketing, spreadsheets, paper forms, and clunky checkout with a system that finishes what participants start.
Program pages, built for you
Your Community Manager builds beautiful, mobile-first pages for every activity, program, and event. No developer, no design work, nothing for you to figure out.
Registration & waitlists
Participants register online in a few taps, and the Assembly team keeps waitlists moving so an open spot never sits empty.
Forms & permissions, handled
We build and maintain secure, structured forms for waivers, medical info, and permissions, tied to every registration automatically.
Payments, processed
Take secure payments through Stripe with transparent fees that drop as you grow, from Basic to Pro to Enterprise. Full reporting, you just get paid.

Everything you need to run programs, without running it all yourself.
Your Community Manager creates, prices, and schedules programs alongside you, then tracks registration status across your whole catalog in real time. No spreadsheets, no double entry, nothing falling through the cracks.




No commitment. Cancel anytime.
A marketplace of every program your members run.
For Associations, municipalities, PTAs, and other organizers: Schools, camps, parks & rec, libraries, city programs, whatever your members run, our team gathers, cleans, and organizes it into one marketplace of rich, actionable profiles - tens of thousands of listings at a time.
