    • Kotlin Development for IT Services Company
      5.0 Feb 2, 2023

      I was most impressed with Slashdev’s quickness to find a developer with the right set of skills. Slashdev has a team of developers, so they immediately understood the project's technical requirements and found the right professional. I found one profile in a week during my research on Toptal and Upwork. Michael found two candidates over the weekend.

    • Kotlin Development for IT Services Company
      5.0 Feb 2, 2023

      I recommend having direct communication with Slashdev and meeting with Slashdev’s CEO. If you try to contact Slashdev through their website, it’s harder to find the right candidate for your project. If you talk to Slashdev’s specialists directly, they’ll understand your requirements and go above and beyond to meet your expectations.

    • Web Design & Development for University Statistics Dept
      4.5 Jan 21, 2021

      They really heard what I said and translated that into visuals that matched exactly what I asked for. Their instincts about what looks good are spot-on. Our company has very specific branding guidelines, and I’m not an expert but I didn’t need to be. Black Antelope already knew UC Berkley’s guidelines. That was so helpful for me.

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.
