Verified client reviews are real, but sponsors can buy their way to the top of the list.

What it's really for A B2B firm directory and lead marketplace. The verified client reviews are real; the ranking position can be sponsored.

What our grade covers The grade on this page is about its agency and firm rankings and 'Leaders Matrix' awards, not everything the site does.

High Scoring Confidence Checked against primary sources. We are confident in the facts and the grade here.

Follow the money

Sponsored providers pay Clutch to boost placement, and its own pages note this "can vault a company to the top of a listing regardless of organic score."

How the grade was reached

Independence · 30% weight 2 / 5

Does the site take money from the very entities it ranks? Pay-for-placement, vendor-funded data, and affiliate commissions all pull this down. The less the ranking can be bought, the higher the score.

Evidence basis · 30% weight 3 / 5

What is the ranking actually built on? Hands-on testing scores highest, then verified first-hand reviews, then opinion or popularity surveys and self-reported figures, then pay-to-rank, which scores lowest.

Method transparency · 20% weight 3 / 5

Is the methodology published, specific, and reproducible? Can a reader see how a given rank was reached, or is it a black box?

Conflict disclosure · 10% weight 3 / 5

Are commercial relationships, sponsorships, and affiliate arrangements disclosed clearly and near the rankings themselves, rather than buried?

Manipulation resistance · 10% weight 3 / 5

How hard is it to game? Controls against fake reviews, solicited reviews, and vendor gaming raise this; an open box anyone can stuff lowers it.
