Agencies say a lot. We show you exactly which parts their clients confirmed.

Every marketing agency's website has a case studies page, and every one of them reads like a highlight reel. There's no way to tell, from the outside, whether a "312% increase in leads" is real, exaggerated, or from a client who no longer exists. Star ratings don't fix this either — they measure how an agency handles a review request, not whether it gets clients results.

OpenServed exists to close that gap. We collect agencies' case studies, and where an agency requests it, we email the named client directly and ask them to confirm, with a single click, that the results are accurate. We also verify a case study through its video testimonial, when one is already published alongside it, at the time it's first added to OpenServed. No forms to fill out, no essay to write — just a yes or no from the person who was actually there, or evidence already on the record. Case studies that clear that bar get a Client-verified badge. The ones that don't are still shown, just without it.

We rank agencies using that signal — see exactly how on the Ranking page. Verified results dominate the ranking on purpose: an agency with one confirmed case study should, and does, outrank one with a hundred unconfirmed claims.

If you're hiring an agency, we want you to be able to trust what you're reading here. If you run an agency with results you can actually back up, we want those results to count for something.
