The breadth of what Mvmnt could accomplish distinguished them from other providers. Valerie is a designer, but she can also work on other tasks that require different skills. If something was beyond her expertise, she had access to providers that could help her. We liked that Mvmnt was a one-stop-shop, and we had a difficult time after the engagement ended. We had to call six different people and manage the team instead of having Mvmnt do everything.

Moreover, Retrocube is more affordable than other agencies that quote around $50,000–$100,000 for this project — one of them even quoted $300,000. Meanwhile, the Retrocube team stays honest with their pricing, which is generally a big issue in this space. Other mobile app companies have surprise fees, but Retrocube has a fixed fee. I like this transparency. We use Basecamp, so I can see what they’re working on, what questions they have, and what progress they’re making in real-time.

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
