    Blue Ripples Technologies has received positive feedback regarding their customer-first approach, with clients highlighting their flexibility and dedication. One client noted that the team led by Vijay demonstrated customer-centricity throughout the project, suggesting architectural changes without imposing their views. The CEO, Sree, was commended for personally assisting during critical production phases, showcasing their commitment to client satisfaction. Overall, the sentiment reflects a strong emphasis on collaboration and responsiveness to client needs.
    • Mobile App & Web Development & Design for Insurance Co
      5.0 Jul 23, 2024

      From the beginning, the BRT team led by Vijay showed customer-centricity while executing the project. They participated in the design, and suggested architectural tweaks when needed but never pushed to us. The project started on-premise and then moved to the cloud, so a lot of technology refitment was necessary which Vijay and the team executed to the utmost satisfaction of the customer. They were flexible, worked late hours and during go-live their CEO Sree came on-site and spent the whole night with the team when the code was being pushed into production.

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.
