    • Frontend App Dev for B2C Software App
      4.0 Sep 28, 2017

      We’re a bootstrapped company, so cost was something we prioritized. Yalantis did a great job with this, compared to a provider in the U.S. who could have been three or four times as expensive.

    • Web App Dev for Food & Beverage Firm
      5.0 Sep 25, 2017

      They offer a good balance between price and work quality. If the same developer came from our country, we would be paying five times more.

    • App Development for Startup
      5.0 Jul 22, 2016

      Part of the reason I used them is they had a very affordable hourly rate for the work that I saw they had online. Also, if I had gotten this done in the United States, it would have been $40,000.

    • Web App UI/UX Design & Development for BioTech Company
      5.0 Dec 17, 2024

      I’m most thankful for Yalantis' quality-to-price ratio. Their pricing is excellent, and we haven’t had to sacrifice the quality of the output for the price. With other companies, we could get really high-quality services, but they're crazy expensive. With Yalantis, we get both high quality and a good price.

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.
