Math first
Budget decisions are pure statistics — fitted curves, marginal returns, confidence intervals. No language model ever touches the money path. The agents draft words; the maths moves money.
About ROASt Labs
Does the work.
Shows the working.
Managing ad budgets across Google, Microsoft and Meta is stuck between two bad options: spreadsheets and gut feel, or black-box automation you can’t interrogate. The tools either report and don’t act — or act and don’t explain.
ROASt is the third option. A statistical engine that fits a response curve to every campaign’s own history, moves each pound to its highest marginal return — and shows you exactly why, every time. Then it checks its own predictions against what actually happened, every night, and shows you that too.
Product principles
Show the working
Every recommendation decomposes into the exact factors that produced it. Every action is logged. And the engine grades its own predictions nightly against reality — the calibration score is on your dashboard, not in our marketing.
Reversible by default
Changes stage before they push. Velocity caps, dry-run mode, kill switches at every level — and anything destructive asks before it acts. You can always see what’s about to happen, and you can always stop it.
Honest about uncertainty
Thin data gets wide confidence bands, not false precision. When the engine doesn’t know, it says so — and explores carefully instead of guessing big with someone else’s money.
