Friend group coordination

Rinney

made it happen

The friend in every crew who remembers what you said you'd do, figures out when everyone's free, and turns "we should" into it's booked.

What Rinney is

Group plans don't fail. They die of logistics.

Rinney is a task-specific coordination and booking assistant that lives in the WhatsApp group your crew already uses. It remembers your recurring intentions, finds the date that actually works for everyone, and handles the part nobody wants to own — the follow-through.

01

Rinney remembers

Every "we should do that" gets logged. Birthdays, blackout dates, preferences — all held in a crew brain the whole group can see and edit.

02

Rinney proposes

When the moment is right, Rinney surfaces a concrete plan: two or three options, cross-checked against everyone's availability. One tap to vote.

03

Rinney gets it done

Once the crew agrees, Rinney names a lead and hands off the booking link — with a clear confirmation before anything is charged. No fund custody. No surprises.

See it in action

The nudge that makes it real.

One well-timed message does more than a month of "we should plan something" threads. Rinney fires when there's a real reason — and always asks before acting.

Tom's birthday is the 12th — and you've all been saying you want to play Bethpage. Looks like Saturday the 14th works for everyone. Want me to grab tee times?

Yes. Finally.

How it works

Built for real crews. Not another app.

Rinney works inside WhatsApp — no download required. It earns its place by doing the things the group chat can't.

🧠

Crew brain

A transparent memory the whole crew can see, correct, and clear. Recurring intentions, key dates, preferences, and constraints — all held and surfaced at the right moment.

📅

Smart scheduling

Cross-references connected calendars and proposes dates that actually work. Members who haven't synced a calendar get a quick poll instead. Nobody is excluded.

💳

Frictionless booking

Once the crew agrees, Rinney posts a direct Stripe checkout link. A clear confirmation gate before any charge — and you never custody funds. The lead pays the merchant directly.

🔒

Privacy-first

Opt-in before any messaging. Calendar tokens and payment methods are encrypted and stored with least-privilege access. The crew can view and delete their data at any time.

Our mission

Friendships don't die in a fight. They die of logistics.

Every crew has that one person — the one who actually makes the plan happen. Rinney is that person, built as software, available to every group. We're not a planning tool. We're not a marketplace. We're the execution layer that turns good intentions into real memories.

We're currently in pilot — working with real crews in New York to prove the coordination loop before we build anything else. If retention isn't undeniable, we don't move on. That's the discipline.
