See how
you know
everyone.

You go to something with forty people, talk to two, and never find out that four others knew three of the same people. topo surfaces that while it still matters.

01 · Before you decide to go

"Three people you'd want to know are going."

That's a different argument from "an event exists." Create one, or paste a link and the details are read off the page. Share by QR or link; others join by code, link or scan.

02 · Standing in the room

Not who someone is. Who to walk up to.

Check in on arrival and everyone here is ranked by shared interests and mutual connections — not recency, not popularity. Each one comes with the reason.

03 · The morning after

The window is about a day. topo uses it.

How many connections the night got you, then who was there you missed — ranked by what you have in common, with one button to add them.

The network map

Trace the route to someone you don't know yet.

Solid rings are people you're connected to. Dashed ones are people they know. Tap a stranger and topo draws the line through whoever links you — then lets you select a handful and start one conversation.

Messaging is direct, group, and one shared thread per event. Nothing else competes for the screen.

Where topo has been used

Real rooms, small ones.

topo works best where the same overlapping group keeps meeting — a gym night, a supper club, a recurring meetup. A few of the events people have run through it:

Why it's different

More than a list of people you were once in a room with.

Most event apps stop at the guest list: names, maybe faces, and a vague sense you've crossed paths. topo remembers what connects you — the people you both know, the interests you share, the nights you were both there — so the second conversation starts where the first one left off.

A guest list tells you

Theo was at Board Game Night.

topo tells you

Theo knows Elena and Maya, climbs on Thursdays, and you've now been at three of the same events.

Who it's for

Small rooms where the same faces come back.

A climbing gymA supper clubA cohortA regular meetup

Deliberately not a feed, a dating app, or a professional network.

Not out yet

The next room you walk into,
you'll know who's there.

topo is in the last stretch before release. Leave your email and we'll tell you the day it opens.
