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.

Cash Management System for Bitcoin Company

5.0 Aug 16, 2018

They were great. They were autonomous, which is what I needed at the beginning. They were open and they integrated with us as a seamless team. The developers worked remotely. We had daily calls, group meetings, and planning sessions. They used Trello initially, but when we incorporated our own Scrum master, we migrated everything to Jira, and they were open to that. We worked in a Scrum methodology so we could iterate the different versions quickly.

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.

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
