Charlie Chang’s apps

Creator Business OS

Combine creator content, affiliate income, sponsorships, and audience growth.

A creator's whole income in one view - ad revenue, sponsorships, affiliate, products - alongside the audience that produces it. It answers which income line is growing, which is fragile, and what a month actually clears after costs.

What a v1 does5 features
  • Every income stream in one dashboard, with month-on-month movement
  • Audience growth shown against revenue rather than on its own
  • Costs and taxes deducted, so the figure is what lands
  • Concentration warnings when too much comes from one source
  • Forecasts for the next quarter from booked work

The market

Proven marketCreator publishing
$42.6Ma year at Kit, bootstrapped, with beehiiv at $30M annualised

beehiiv grew from $19.8M at the end of 2024 to $30M by June 2025, with paid plans from $49 a month. At $59 a month this costs a little more, for a different job: tracking a creator's income rather than sending their newsletter.

Why this audience

This audience runs content, affiliate income and sponsorships at once and has no view of the whole. They already think of themselves as running a business rather than a channel. One dashboard across every income line matches that self-image.

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.

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.
