I built a marketplace agency that treats profit as the actual metric

We built Adverio after watching brands celebrate revenue growth while their margins quietly collapsed from inefficient ad spend and poor listing conversion. The problem is that most Amazon agencies optimize for ad-attributed sales. That number looks good in a report but hides a lot. We wanted to build something that worked backward from profit instead. So we manage the full stack: sponsored ads, DSP, listing copy, account operations across Amazon, Walmart, and Target. But the reporting we built internally focuses on contribution margin, not top-line ROAS. Technically nothing exotic here. We're pulling from the Amazon Advertising API, Walmart Connect, and Roundel, normalizing it, and surfacing the numbers that actually matter to a brand operator. We'd genuinely like feedback on how you'd think about benchmarking this kind of service.
