Your logs already know.
By the time the report confirms it, you had already suspected it for weeks. The logs knew it live: which partners were working, which were not, what was worth shifting. We read them while the campaign runs, put every recommendation on the record before you act, and grade it after; it works on media first, and on almost anything with a cost and an outcome. Three ways in below; start with the one that matches your job.
See which partners are earning their money while the campaign is still running. Not after.
Your reporting can already drill as deep as you want: partner, geo, creative, hour. Your MMM and clean rooms already join across partners and take the overlap out. What neither hands you is the move: platform slices are counts each platform credits to itself, and the joined reads land in weeks, at channel grain. The log-level rows your programmatic, CTV, and ad-server buys already produce can say which partner, segment, and path is earning its price right now. Every recommendation is written down before you act and graded after, because some calls are wrong; the difference is you know within days, the budget moves, and the next read carries the correction.
One capability your systems and agents just call.
A closed box with typed inputs and outputs: send rows with a cost column and an outcome column, get back contribution values, predictions with confidence bands, and the decision record for the run. It runs in your cloud, ours, or your customer's, and your data never leaves. A dishwasher, basically: you know what goes in, you know what comes out, and nobody has to watch the middle.
Companies that never met, doing business on the record.
Every capability carries its own graded track record: predictions written down first, outcomes graded after, signed. The other side does not have to trust anybody; they read the record, and the money splits by what the record shows.
The read is the product you start with. The record is what accumulates. The network is what the record makes possible.
Which of the three is actually painful for you right now? Start there.
When what your company knows joins.
Everything above gets sharper when what your company knows joins the read: which client hates surprises, what a win means on each account, which commitments cannot bend. That knowledge is captured from the work your team already does, shows up only in the read that needs it, and never leaves your control. The graded record tells every agent what worked; what your company knows tells it what matters to you.
