The all-in-one platform for clubs, teams, and groups.

core.club is the platform for member-run organizations — modular, modern, and easy to pick up on day one. The same toolkit stretches from a five-person book club to a five-thousand-member league.

01
Evolving library

Every module your club could need — and the ones you ask for.

Directory, message board, schedule, dues, courts, ladders, scorecards, reading lists. New modules ship every release; turn on what you use, leave the rest off.

02
Shape the platform

You're not a customer. You're a founding club.

Request features directly from the app, vote on what gets built next, and talk to the people building it. Every early club leaves a fingerprint on what core.club becomes.

03
Invite-only — for now

Request an invite. Bring your whole club.

We onboard new clubs in small waves so support stays personal. Once you're in, invite unlimited members — there's no per-seat cost, ever.
