Multi-market · Latin America · Demand validation

The two-market template, run for the first time on Citibanamex.

A Citibanamex D10X concept tested first in Peru and then in Mexico, four months apart. The synthesis-translate-test-compare loop became the canonical Prota multi-market template.

Challenge.

Citibanamex had a hypothesis that resonated in one Latin American market but wanted to know whether it would translate. The decision Citi brought us was: which market first, and how to design the second market's test so the read is comparable rather than a re-do.

Approach.

• Run market 1 to clean signal first. Synthesize.
• Translate the landing page and creative for market 2. Hold the underlying value proposition constant; localize the language and the cultural frames.
• Run the second demand test with the same audience targeting principles and the same conversion-tracking instrumentation.
• Run the comparison synthesis as a separate deliverable, not folded into either market's individual readout.

Outcome.

• Validated in both markets with comparable signal across the translated landing pages.
• Multi-market template documented, the synthesis-translate-test-compare loop is now the Prota canonical model for any "which market first" launch question.

Methodology lessons.

• Two-market parallel smoke test for "which market first" questions. Plan a full quarter between markets at minimum.
• Comparison synthesis as a separate deliverable, kept clean from each individual market's readout.
