The problem
Every group plan begins with "when is everyone free?" and then dies there — in a chat thread, a poll nobody finishes, and four screenshots of four calendars.
The tools that exist ask you to schedule an event and then find people for it. The actual constraint runs the other way.
What I built
Flok inverts the order. You make a group, everyone marks the dates they can't do, and the calendar immediately shows which dates work for the most people.
Marking unavailability is a much lower-effort ask than proposing times, and it's the input that resolves the question — so the group gets an answer in one pass instead of a negotiation.
Selected details
- The product
Create a flok, invite members, mark blackout dates. The shared calendar aggregates everyone's input into a readable percentage per date, so the best days surface without anyone tallying anything.
- Stack
iOS client on a Supabase backend.
- Launch
Reddit and community launches, influencer and university outreach, short-form video, and direct outreach — running the acquisition side myself rather than treating launch as someone else's job.
Screens
Where it landed
Roughly 30 users on day one and around 60 through the early launch period, from cold distribution with no existing audience.
What I took from it
- Consumer is a different discipline from B2B, not a lighter one. Branding, group mechanics, and the first-run experience carry weight that a feature list doesn't.
- Getting the first thirty users is a product problem as much as a marketing one — the invite loop is part of the product.
