Case 04Ecom · Sustained Performance

13.7x ROAS, sustained.

A direct-response ecom brand maintaining a 13.74x average ROAS across 57 daily reporting cycles in August 2026. This is not a peak week or cherry-picked campaign. It is the average held over hundreds of measurement points across a full month of active spend.

The Engagement

Performance-based agreement structure. No flat retainer. Viestri is paid as a percentage of attributable sales, tied to a 30-day rolling actual-ad-spend band. Incentives align tightest here. Viestri profits only when the client profits, and the result is the discipline you see in the numbers.

Operating cadence
What 13.7x ROAS means in practice. Every dollar of ad spend returns 13.74 in attributed revenue. Across 183 purchases, this is not luck. It is the compounding result of running a tight system on a brand with strong product-market fit, and never letting the ad account drift even one week.
