Spin.

The idea, simply.

Every weekly golf group has the same problem: getting four people on the same tee time without melting the group chat. Some people say yes early, drop late. Some people only show up when someone else nudges them. The course wants the booking. The group wants to play. The chat doesn't want any of it.

Spin handles the round-up. Pings the regulars. Tracks who's in. Holds the tee time. Lets the course know when the group's confirmed. Nothing weird. Nothing AI-shaped about it from the outside.

Who it's for.

• Groups that play together regularly — weekly, monthly, holiday rounds
• The person in the group who somehow always ends up being the organizer
• Courses that want a calmer way to fill recurring slots

Where it is.

In development. Real users in mind, real golf groups, real courses. Not a side project. A tight surface area that wants to do one thing exceptionally well.
