YouTube Portfolio OS

Manage multiple YouTube channels and track revenue, RPM, growth, costs, and profitability.

For somebody running several channels rather than one: revenue, RPM, growth and cost side by side, so the question of which channel is actually worth the next video has an answer. It pulls the numbers from YouTube and adds the costs YouTube does not know about.

What a v1 does5 features
  • Every channel's revenue, RPM and growth in one table
  • Editor, thumbnail and freelancer costs entered per video
  • Profit per video and per channel, not just revenue
  • Which formats and lengths earn most, per channel
  • Alerts when a channel's RPM or retention moves sharply

Why this audience

This audience is unusual in running more than one channel - the content actively encourages it. That creates a problem almost no creator tool handles: comparing channels on profit rather than views. The multi-channel behaviour comes first, the need follows it.

Before it can launch

  • YouTube Data and Analytics API OAuth review, plus a quota increase - the default quota does not cover a portfolio of channels

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.
