The 3 Things

Minimalist productivity app centered on choosing the three most important tasks each day.

Three tasks a day. Not a list, not a project tree - three. Everything else waits, and the day is judged on whether those three were done.

What a v1 does5 features
  • Exactly three tasks a day, enforced
  • Everything else parked in a backlog that is not shown
  • A single end-of-day verdict: done or not
  • Streaks on days completed
  • Carry-over made deliberately visible when it happens twice

The market

That is about 0.6% conversion at the most successful independent task manager there is. Motion went from $2M to $50M in under two years charging $19 to $34 a month, and Sunsama charges $16 to $20. At $4 a month this is priced below both.

Why this audience

These viewers have tried and abandoned elaborate productivity systems, which is a pattern the content addresses directly. The appeal of three tasks is that it is the opposite of what has already failed them. The audience has been pre-sold on minimalism by their own experience.

Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.

Is this the one for your audience?

We fund it, build it, and run it. You bring the audience and take a share of the revenue. Nothing to pay and nothing to build.
