Charlie Chang’s apps

Operator OS

Umbrella platform connecting business building, agency, affiliate, YouTube, sponsorship, and founder productivity.

The umbrella over the whole operation: the businesses, the agency work, the affiliate income, the channels, the sponsorships and the founder's own week. One place for somebody running several things that all feed each other.

What a v1 does5 features
  • Every venture in one dashboard with its own numbers
  • Revenue across all of them, and where the time went
  • Cross-venture view - what one is doing for another
  • The founder's own priorities alongside the businesses
  • One price for the whole platform, not per module

The market

Adjacent marketTask and daily planning
50M usersat Todoist, of whom roughly 300,000 pay

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 $249 a month this is more than seven times the most either charges. It is priced as the platform the other 42 ideas on this list roll into rather than as a planner, and nothing in this table proves that price.

Why this audience

The far end of this audience runs several things at once - an agency, affiliate income, channels, sponsorships - and the founder is the only integration between them. They have been encouraged into exactly that shape. One platform over all of it is the answer to a problem the content created.

Before it can launch

No licence, certification or data agreement stands between this and a launch — app-store review and an ordinary privacy policy aside.

How the pricing works

One price for the whole platform. Priced module by module it reads as six things to buy and six decisions to make; this is the bundle the other forty-two ideas roll into.

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.
