MVP Build & Branding for Blockchain Tech Company

5.0 Jul 16, 2020

What I find most impressive, besides their tech skills, is their professional and client-focused attitude. They have been very responsive, very flexible, very communicative and an absolute pleasure to work with. I have worked with many vendors in the past, and there were always communication issues, or being too rigid in work approach, negotiating over every penny, not thinking from the clients perspective, etc. With LimeChain I have not experienced any of these issues.

In terms of communication, things are pretty great. We have weekly calls and online meetings with team members. Everybody participates and gives their input into the project, so everybody is on the same page and actively involved to finish things on time. Part of the difficulty came from the fact that the creative agency was also involved but not 100% leading the project. Now, we’ve streamlined the whole communication, and things are moving quicker and better.

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.
