Web Development for Blockchain Game

5.0 Jan 27, 2022

RedDuck works hard, and if they can’t get their stuff together, they work late in the night. I live in Thailand, so it’d be nice for me if they started working at 10:00 or 11:00 a.m. I understand that it's too early for them, and they work late nights. However, it’d be a nice upgrade if they hired someone to pick up work in the morning.

Blockchain Development for Scientific Research Startup

5.0 Aug 8, 2018

Initially, we didn’t use a project manager or exact timelines because the scope kept changing. We made last-minute changes that they often accommodated within 24 hours. The team was flexible, but now uses a project manager and Jira to organize the project. LimeChain converts data from Jira into timesheets to invoice us. While the team could improve its project management skills, they’re more transparent than they used to be.

Blockchain Development for Property Protection Company

5.0 Aug 7, 2018

The team is very professional. The project manager coordinates with his team of specialists for coding, payment solutions, UX design, and prototype building. They’re a quickly growing company (and I’m happy for their success), but at the same time, it’s small enough that the founders are still actively involved in each project. LimeChain is transparent with transparent and accurate reporting. Neither their scope nor budget deviates, which is important for projects like this one.

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.

A Clutch Leaders Matrix provides a broad view of the top-performing companies in a particular service or location. Each company featured in a Leaders Matrix is evaluated based on Focus and Ability to Deliver. The size of each circle indicates that company’s size.

By using verified reviews, focused service details, and real project data, the Leaders Matrix highlights companies that consistently deliver and stand out from the rest. Each company’s position is based on how well they focus on a service area and how consistently they deliver results, helping you make informed, confident decisions. Learn More
