    • Software Development for Travel & Tourism Platform
      5.0 Apr 1, 2020

      The project management was one of the greatest experiences with Andersen, on several levels. First, they assigned a highly-skilled PM to the project who was able to understand business requirements, manage the team and drive the implementation. But what was even greater: As we iteratively established a highly agile way of work, the PM stepped back from an active, „push-style“ management into a more lateral role where she acted rather as team manager and Agile Coach.

    • Software Development for Travel & Tourism Platform
      5.0 Apr 1, 2020

      The project managment and communication, in general, were outstanding. PM and devs were always very responsive, we knew what everyone was working on and how their progress was. At the same time, the Andersen team worked in a very self-reliant way, and we knew that our products were in good hands.

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.
