How we rank
Each agency is scored out of 100 on platform depth, evidence (case studies and outcomes), certifications we could verify, price transparency and how recently the site was updated. Paid listings get a badge but no rank boost.
How to shortlist
Pick three with a case study close to your use case, ask each how they test an agent before launch, what a run costs in model fees, and who maintains it after go-live.
