Forget fixed 50/50 splits and weeks of waiting. Foundry uses Thompson Sampling to shift traffic toward winners in real time, plus a persistent holdback for clean lift measurement. The result: results faster, ad budget intact.
From the first visitor, traffic flows toward the variant most likely to convert. Losers shrink. Winners scale. No predetermined sample size required.
A small persistent holdback sees the unoptimized control. Lift is measured against that group, in real time. Causal proof. Not before/after correlation.
Variants are coordinated strategies (headline, subhead, CTA, social proof together), not isolated swaps. Coherent variants beat single-element experiments.
AI generates coordinated variants per campaign and audience, informed by ad context, brand voice, and customer language. Human approves before they go live.
Thompson Sampling routes more traffic to winners as evidence accumulates. Cycle reaches a decision with 50 to 75% fewer visitors than traditional A/B.
Losers don't just stop running. Their failure context feeds the next generation of variants. Each cycle is smarter than the last.
Thompson Sampling. Holdback testing. No CRO specialist required.
