Lunch with people you have not met.
Group Mixer splits a room into random tables for lunch or breakouts. Everyone scans one code, finds their group by the shape on their phone, and gets new faces when the round turns over.

Round 1 of 2
2 of 6 found their group
Let each group find its table and sit down.
How it works
- 01
Everyone scans, then the room splits itself
Groups are made when you start, from whoever is actually there. Choose how many people sit together, or how many groups you want, and the sizes come out within one person of each other.
- 02
Every table holds up the same shape
Each group gets a coloured shape on every member's phone, so a table finds itself across a full room. Somebody who arrives late is seated straight away, and a room that fills up after you start gets more tables.
- 03
Phones go away until the round ends
Rounds run 5 to 90 minutes. When one ends there is a 15-second goodbye and everybody gets a new table, with as few familiar faces as the room allows.
Why the seating plan is the whole event
Tell a room to sit with new people at lunch and it will nod, then sit with the people it came with. Nobody is being difficult; choosing a table of strangers is a small social risk, and everybody is waiting for somebody else to take it first.
Group Mixer takes the choice away, which is the kind thing to do. The groups are made from whoever is in the room when you start, each table has a shape to find it by, and anybody who wanders in late is given a seat instead of an awkward look around the room. Nobody has to decide where to sit, so nobody has to feel brave about it.
Then it gets out of the way. The phones go back in pockets, the clock runs on its own, and if you set a second round the tables reshuffle so everyone eats with new people twice. What a room remembers afterwards is not the app. It is who they sat with.
FAQ
Group Mixer, explained
How does Group Mixer work?
Everyone scans one QR code. When you start, the room is split into groups and each phone shows a coloured shape plus the names of the people at that table. Everybody in a group has the same shape, so people hold their phones up, find each other and sit down. Then the phones can go away until the round ends.
How are the groups sized?
Two ways, and you pick one: about how many people should sit together (3 to 12), or exactly how many groups you want (up to 30). When the room does not divide evenly some groups get one more person, and nobody is ever left in a group of one.
What if people arrive late?
They are seated as soon as they join — at the smallest group, preferring one where they know nobody. If you started with only a few people in the room, new tables open as it fills up, so a late crowd is not squeezed onto the first table. Nobody waits for the next round.
What if somebody closes their phone and comes back?
Their seat is kept. Reopening the link on the same phone puts them straight back at their table. If they come back on a different browser and type their name again, they are given their old seat back too, as long as the earlier phone is no longer connected.
Do groups get something to talk about?
By default, yes: a topic from a built-in bank of 140 questions in 7 categories, one per table or one for the whole room on the big screen. You can use your own list instead, or switch topics off and just mix the seating.
How long does it take?
The default is 2 rounds of 30 minutes, about 60 minutes in all — a lunch with one change of tables. Round length is a slider from 5 to 90 minutes, and you can add time to a round from your phone while it runs.
Will people end up with the same people again?
Each new round seats people with as few familiar faces as possible. Larger tables use up a room's strangers faster than pairs do, so after a few rounds some overlap is unavoidable — the activity keeps it to the minimum.
Do participants need an app or an account?
No. They scan a QR code or open a link and it runs in their phone's browser. Nothing to install and no sign-up.
How many people can join?
The Free plan supports up to 50 participants per live activity, Pro raises that to 150, and Badass supports up to 300 — enough for a full floor at lunch.
