The networks optimise inside their own auctions. The Growth Brain decides how they work together.
Google, Meta and TikTok each run a bidding system you cannot beat from the outside, and the Growth Brain does not try. It works one level up: which channel deserves budget, which business outcome each should optimise toward, which audiences to expand or suppress, which creative and landing pages to test. It plans the analysis, calls the attribution service, the budget engine and the business metrics service for the numbers, then writes the reasoning around what they return. Every move it proposes is tested against the Campaign Constitution before it reaches an ad account.
In practice
Demo dataWhich channel deserves another €5,000 this month?
Meta. Over the current 14-day window its customers are recorded at a CAC of €121 against Google's €184 and your €140 target, and over 90 days customers credited to Meta carry €14,800 more collected revenue than Google's on 15% less spend. The evidence is the metrics service window, CRM opportunity stages and invoiced value from your finance system, all under your last-non-direct rule. Business impact: the budget engine projects 31 additional customers over the next 30 days if €1,200 a day moves, at the current blended rate. Confidence is high — fourteen days of data, above your 30-conversion evidence threshold. The alternative reading is that Meta's audience skews to annual plans, so part of the gap is plan mix rather than channel quality, and only a geo holdout would separate the two. The recommended action is ACT-2291: move €1,200/day from Google Prospecting to Meta Prospecting. Constitution check passes — inside the €1,500 daily movement limit, and 7.0% against the 15% daily change cap.
Above the auction, not inside it
Performance Max, Advantage+ and Smart+ keep doing what they are built for: delivery, placement and bidding inside one network's inventory. The Growth Brain sets what each of them is pointed at and how much it gets. Native network AI is the execution layer it coordinates, not a competitor.
The model plans, services compute
CAC, ROAS, attributed revenue and margin come from the business metrics service, the attribution service and your finance system. The model decides which analysis to run and which tools to call, then explains the result in plain language. It never derives a figure of its own.
Decisions are stored objects
A reallocation is written as DEC-8841: the objective it serves, the evidence rows it used, a frozen metric snapshot, the constitution checks it passed and the expected impact. Six weeks later anyone can open it and see the state the decision was made in. Reversal restores the previous budgets from that same record.
Behind one answer
- Answer
- Meta. Its customers are credited with €14,800 more collected 90-day revenue than Google's on 15% less spend.
- Evidence
- 311 customers, 90-day window, invoiced value from the finance system, last-non-direct attribution.
- Business impact
- Moving €1,200/day would add an estimated 31 customers this month.
- Confidence
- High — 14 days above the minimum evidence threshold.
- Alternative explanation
- Meta's audience skews to annual plans. Some of the gap is plan mix rather than channel quality.
- Recommended action
- Move €1,200/day from Google Prospecting to Meta Prospecting.
- Constitution check
- Passes — within the €1,500/day movement limit.
Intelligence
The rest of the intelligence layer
The Growth Brain
The planner above your ad accounts. It decides which channel gets the next euro, and what that euro is pointed at.
Ask AI
A question resolves into a window, a cohort, an attribution rule and four service calls — and the plan is shown beside the answer.
Actions
Every change to an ad account is an action object: checked against your limits, logged, evidenced and reversible.
Recommendations
A ranked queue of what to do next — each item with its evidence, the spend it affects and the rule it clears.
Forecasts
What a budget is likely to buy over the next 30 days, with the range, the assumptions and the later score.
What Changed
A diff of your advertising since the last read: your changes, the networks' changes, ranked by money at stake.
Why It Changed
Decomposition names the segment carrying a measured difference. It does not prove that segment caused it.
Evidence
Every figure opens into the rows behind it: which service computed it, over which window, under which rule.
Business Objectives
One written objective — outcome, target CAC, maximum CAC, margin floor, markets — that every channel is judged on.
