At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.
Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.
Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.
We evaluate service providers using a structured methodology that combines:
- In-depth client interviews and ratings
- Comprehensive project details
- Market presence
- Portfolio examples and industry recognition
This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.
Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.
We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.
