Who’s In

Whosin

Your city is calling. Who's in?

AI-powered weekend planning for SF locals. Tell us your vibe, join real people, make memories.

The problem

Friday nights disappear to "what should we do?" You want to get out. Friends are busy. Scrolling through 1000s of options kills the vibe. You stay in instead.

How it works

✨ Tell your vibe Active, chill, romantic, foodie — or let AI surprise you

🤖 AI picks Real SF activities matched to what you actually want

👥 Join strangers Meet 4–6 like-minded people. No friend group required

⭐ Build trust Rate hosts. See your rating. Safe, transparent, social.

What's coming

Phase 2 (Now) — Validating demand with early users in SF Phase 3 (Q2 2026) — Building the MVP. Private beta. First 50 users. Phase 4 (Q3 2026) — Public launch. Open to all SF locals.

Questions?

Why would I join strangers? Because your friends are flaky, but 6 people with the same vibe as you probably aren't. The host rating system means you know who you're meeting.

Is this free? Free to start. Premium tier ($9.99/mo) unlocks personalized AI recommendations and early access to new activities.

How is this different from The Nudge or Eventbrite? The Nudge sends the same plan to everyone. Eventbrite is for big events. Whosin learns your taste, lets you join strangers with trust built in, and builds a real social graph.

When can I use it? Private beta Q2 2026. Join the waitlist to be first.
