How it scored
Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.
How we scored this
We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.

Verdict
Clay clears the bar for a well-funded brand that values top-tier product and web design. Its UI/UX depth, creative quality, and review base are strong.
Honesty requires naming the cost risk: Clutch summarizes some concern about price relative to deliverables and advises clients to clarify objectives upfront. Use a tightly bounded scope, milestone approvals, and a maintainability plan; do not pay prestige pricing without measurable business and technical acceptance criteria.
