Valuation Platform Dev for Startup Acquisition Marketplace

5.0 Dec 20, 2021

When working with an outsourced company, we look out for three key things: trust, competitive pricing, and reliability. Yalantis checked all of those boxes; they were very open and transparent about their pricing and the use and release of credentials. They also put a lot of diligence into breaking the project down into engineering hours per person. They went on to track that on a weekly basis, which was key to making sure that we were on track with our goal while staying within our budget.

Web App Development for IoT Device Retailer

4.5 Nov 23, 2022

Any interaction that we had with Cogniteq was a pleasant one. Even despite the fact that we had a rather long project, there was a holiday season and some specialists had vacations, everything went smoothly. The guys dealt well with all the tasks and the communication from Cogniteq was excellent. They put in place an account manager who was our main point of contact but we also had contact with the actual developers, testers and analysts as we wanted.

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.
