[ 01 ] CONNECT · 10:04
Connect everything. Fix what's broken.
Any other Monday, this hour goes to the pacing spreadsheet. Instead: Google, Microsoft and Meta connect in one OAuth flow, campaigns and budgets pull in automatically, and ROASt audits every account as it lands. Broken conversion setups are auto-fixed; anything it can't fix is flagged with a one-click resolve.

[ 02 ] GROUP & MODEL · 14:31
Group your campaigns. Watch the models grow.
Pull campaigns into portfolios: brand, generic, PMax, whatever shape your account takes. ROASt fits a Hill response curve to every campaign and re-fits it nightly; its slope answers “where does the next pound work hardest?” at every level of spend.
[ 03 ] GOALS · 16:45
Tell it what winning means.
Every portfolio gets a goal: platform conversions, GA4 revenue, Shopify orders, or closed deals straight from your CRM, plus the ROAS or CPA target you’re accountable for. From here on, the engine optimises your definition of performance, not the platform’s.
You log off. ROASt clocks in.

While you sleep, budgets move.
Marginal-ROAS scoring redistributes campaign budgets every night to maximise performance against the goals you set that afternoon. Approved changes flow back to the platforms via their APIs. No spreadsheets. No 2am logins.

[ 05 ] THE TEAM · 03:30
Nine specialists on the night shift.
Three Optimisers act on your account. Three Watchers alert you to change. Two Analysts explain the numbers. And Flume, a generalist you can talk to in plain English. Claude where it helps. Deterministic math everywhere else.
[ 06 ] MEASURE · 07:00 TUE
Wake up to work done. Summarised.
Every push is observed against actual outcomes: the engine grades its own predictions, and confidence compounds with every cycle. Your morning brief lands at 7am, client-local. KPIs, what changed, what to act on. One page, ready to forward.

Tailored to how ad platforms actually behave.
The engine is pure math and modelling, no LLM involvement, which is how it should be. Platform adaptors are trained on platform behaviour and apply nuance and safeguarding to campaign scoring.
How the engine worksMeta Ads
Native learning stages, dwell windows, and creative cycles, respected in their own language rather than papered over.

Smaller auction volume means more caution, more compounding, and a harder watch on budget that isn’t spending.
