The autonomous layer above your ad platforms.
YEpsilon optimizes ad-spend ROAS across Google, Meta, and LinkedIn using your first-party data — making the cross-platform decisions the ad platforms can't.
The idea
Above the ad platforms — not against them.
Google Smart Bidding and Meta Advantage+ are excellent at optimizing withina campaign. They can't see across your whole account, across platforms, or across the first-party data that actually tells you which customers are worth winning.
That's where YEpsilon lives. It sits above the platforms and makes the decisions they structurally can't: cross-campaign budget allocation, cross-platform reallocation, statistical-confidence kill decisions, and creative-fatigue detection — all driven by your data and a transparent Bayesian engine.
How it works
The intelligence the ad platforms leave on the table.
Every capability is built for one job: compounding ROAS by making better decisions than rules-of-thumb or any single platform's black box.
Bayesian ROAS engine
A Beta-Binomial model evaluates every keyword and ad set on credible intervals — pause, hold, scale, or reduce bids — so decisions follow statistical confidence, not last week's noise.
Cross-platform allocation
Budget moves to where it actually earns, reallocated across Google, Meta, and LinkedIn instead of being trapped in a single platform's silo.
Smart Bidding staging
Campaigns progress through bidding strategies as they accumulate signal — with rollback detection if an automated strategy underperforms.
Creative-fatigue detection
It spots fatigue before performance craters and flags creatives for refresh — protecting spend that would otherwise quietly leak.
Persona intelligence
First-party CRM and product-analytics data become personas and precise ad targeting — turning your data into an audience advantage.
Conversational campaigns
Create, brief, and launch campaigns through a chat interface, then let the engine monitor and optimize them autonomously.
