intimate by design

Built for your group chat energy — at profile scale.

The best room you’re in already has a name and about fifteen people. wack is that room, with a profile, a feed, and the lights done right. Not a stadium. A living room you actually want to sit in.

“Your circle” isn’t a metaphor. It’s a number.

Anthropologists call it Dunbar’s number — roughly the count of real relationships a human brain can hold. Big Social pretended it didn’t exist and sold you 4,000 strangers. We built around it instead.

5

The inner ring

The ones who get the unfiltered take. Your 2am people. Post here and it lands like a whisper, not a billboard.

15

Your good friends

Close enough to crash on the couch. The room where the running jokes live and nobody needs a caption explained.

50

Your wider circle

Friends, the good cousins, the ones you'd grab a drink with. Big enough to feel alive, small enough to still feel like yours.

Concentric, not a single blob. You decide which ring sees each post — so closeness stays closeness.

Friends first. Then friends. Then, still friends.

Your feed is strictly the people in your circle, in the order they posted. No ranking model, no “suggested,” no stranger going viral in slot three. If you didn’t invite it, it’s not in here.

The lesson Cohost taught the internet before it closed: people didn’t want a bigger megaphone. They wanted a smaller, kinder room — and they’ll pay attention when one exists. So we made one that intends to stick around.

What never makes the feed

  • An ad. Not the first one. Not a sneaky native one.
  • A reel from someone three states away.
  • A post engineered to make you angry enough to share.
  • A stranger, ranked above your best friend's news.

Chronological is not a feature we’re testing. It’s the whole point.

You grow your circle. We don’t guess at it.

There is no “people you may know.” We didn’t read your contacts, we’re not triangulating your shadow profile, and we will never surface your therapist. Every connection here happens because a human made it on purpose.

Send an actual invite

A link, with your name on it. They join because you asked, not because a model decided you two should know each other.

Scan to swap

Your profile QR lives on your lock screen. Met someone good tonight? One scan, you're connected. No phone-number ransom.

Real intros

Vouch a friend into a friend's circle. A warm handoff, the way it works offline — never a cold 'people you may know.'

Kindness, by structure.

We’d rather design good behaviour in than moderate bad behaviour out. A short rulebook helps — but mostly, small rooms with no audience and no scoreboard just bring out better people.

Small rooms behave better

Nobody performs cruelty for fifteen people who'll see them at brunch. Scale breeds contempt; intimacy breeds manners.

No public scoreboard

Counts are off by default. With no audience to win, the incentive to dunk quietly evaporates.

You set the room

Post to five or to fifty — you choose the size of the audience every time. Oversharing is a setting, not a default.

Small circles, fully formed people.

A few of the folks who traded the megaphone for a good room. Names changed; the energy is real.

@maraquinn

Curates a circle of exactly 11. Says 12 would be 'a crowd.' Posts mostly soup.

Left a 4,000-follower account to talk to nine people who actually text back. No regrets, fewer notifications.

Runs the group chat that runs the friend group. Finally has a room with better lighting.

Your group chat deserves a better-looking room.

Claim your handle, invite the fifteen who matter, and leave the strangers on the platform that’s monetising them.
