Sponsor slots priced on what viewers actually watch.

CreatorFlow reads a channel's own analytics and prices each ad slot on how many viewers are still there when it runs. When the video goes live, both sides get the report on the right: what was agreed, what was delivered, measured from the same source.

Free for creators. Read-only access to your own analytics, revocable at any time.

1

Verified impressions are viewers still watching at the slot position, measured from the retention curve. Subscriber counts never enter the calculation.

2

The curve comes from the creator's own connected YouTube Analytics, organic views only. The shaded window is exactly what was bought.

3

Terms were declared inside CreatorFlow before the video went live. That declaration is what makes this report possible.

4

Publication and delivery are detected automatically from the same analytics. Neither side fills anything in, and neither side can edit the result.

For creators: a rate you can defend

Most sponsorship rates are a guess dressed up as a norm. Yours can be a measurement. Connect the channel and the advisor shows your retention curve with a draggable slot window; the price updates as the window moves, because the audience at minute six is not the audience at minute forty.

  1. 01

    Connect

    Read-only OAuth to your YouTube Analytics. We never touch uploads, comments or revenue data.

  2. 02

    Price

    The advisor derives a conservative forecast from your trailing uploads and prices the slot on viewers present at that minute.

  3. 03

    List

    Your storefront shows the rate to signed-in buyers and takes their proposals. No exclusivity asked of you.

  4. 04

    Deliver

    Publish as normal. CreatorFlow detects the video, measures the slot, and writes the report on its own.

For buyers: a number your finance team can interrogate

Subscriber counts measure history. You are buying attention in a specific ninety seconds of a future video, so that is the thing CreatorFlow forecasts, prices and then verifies against the channel's own delivered analytics.

Free, and it takes a minute. Rates sit behind it so creators know who is looking.

Flow ScoreBased on 4 of 4 signals

Flow Score ranks, it never prices

One figure for comparing channels, built from four measured signals. An example is shown; a real channel scores on whichever of the four it has the history for, and the rest stay out rather than being guessed at.

Buy against the cautious end
Every forecast is quoted at its 25th percentile. If the video performs typically, you get more than you paid for, and the report says so plainly.
Agree terms where the data lives
Proposals, negotiation and the declared price all happen in the deal room. Settlement stays between you and the creator by ordinary invoice.
Get the delivery report
At day 14 and day 30 the report lands with delivered impressions, the retention curve, and the disclosure check. It exists nowhere else.

What these numbers are not

A marketplace that only shows you flattering figures is selling you something else. Before you rely on ours, you should know their edges.

A forecast is a forecast. We quote the 25th percentile and verify what was actually delivered; we do not promise outcomes.

On-target impressions rest on stated assumptions about audience composition. The methodology page names each assumption and the direction it biases the estimate.

None of this is MRC-accredited measurement, and we say so on every report.

CreatorFlow holds no money. Creators and buyers settle directly by invoice, and payment declarations never gate the report.

The full methodology, including what we get wrong

The first creators set the standard

This is for long-form channels who want their rate anchored to something they can show a sponsor. Connecting takes a minute, the analytics product is free, and you get a storefront you can send a buyer to the same day.
