Case 03 US · DE · UK · D2C Health

Three countries, one system.

A multi-country D2C health brand running simultaneous Meta Ads campaigns across the United States, Germany, and the United Kingdom. Viestri delivers automated weekly reports with creative-level diagnostics for all three markets on a single unified cadence. Each market operates with its own ad account, its own creative library, its own audience structure, and its own currency-aware threshold tables, but the client receives one cohesive growth narrative every Tuesday.

The Engagement

SS-Tier intelligence engagement. Each country runs as a discrete ad account with country-specific creative variants, audience targeting, and performance benchmarks. The three markets report through a single Tuesday cadence with cross-market pattern recognition baked into the workflow. When a creative angle wins in one market, it gets adapted and tested in the others, with the threshold table per country governing whether it scales.

Sample weekly outputs (May 17 to May 23, 2026)

Market	Reporting Period Result	Action Issued
United States	43 purchases · $70.08 CPA · 0.72 ROAS · 1.77 frequency	Reallocate to top creative; hold total budget
Germany	17 purchases · €227.08 CPA · 1.17 ROAS · 2.51 frequency	Scale top creative; combat frequency rise
United Kingdom	£1,001 spend · 105k reach · Purchase tracking issue diagnosed	Pixel audit; pivot to conversion-optimized campaign

What the system does that single-market agencies don't

Cross-market creative testing. A winner in Germany gets adapted for US and UK, with separate creative briefs honoring each market's cultural and linguistic context.
Currency-aware threshold tables. CPM, CPA, and ROAS ceilings are set independently per country in each native currency, with auto-pause logic tuned to each market's economics.
Pixel and attribution diagnostics built into the weekly report. When UK Purchase events failed to fire, we caught it through the funnel review and issued a tracking audit before the client lost a week of optimization signal.
Single-narrative weekly delivery. The client receives one Tuesday report covering all three markets, not three reports they have to synthesize themselves.
Lookalike audience expansion isolated by market. 1–3% lookalikes built on recent purchasers per country, tested in dedicated ad sets without contaminating the core audience structure.

The hard part isn't running three ad accounts. The hard part is making three accounts feel like one cohesive growth function, with consistent language, consistent diagnostic standards, and cross-market learning. That is the intelligence layer in action. It is what separates a multi-country D2C operation from three disconnected single-country accounts that happen to be on the same invoice.
