    • Custom Software Dev for Software Development Company
      5.0 Nov 3, 2022

      Altoros' management and individual contributors (engineers, architects, etc.) manage their transparency with tools and excellent Business English. At times it felt like we were working with much more expensive consultancies and not extended programming teams. We used standard means of communication, but where they overdelivered was with honesty, simplicity and care. You do feel like you are working with human-beings and not algorithms that generate reports.

    • Software & Mobile App Dev for Digital Solutions Company
      5.0 May 5, 2021

      Readiness to find out new and cost-effective way to develop the final product. Open and honest communication throughout the project game us room to review different UI functions on the service. While the quality of the work was great, they could have been more diligent about documentation and more accurate estimations of the work packages.

Why Trust Clutch

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.

Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.
