Dynamic Mobility Platform Dev for Transportation Marketplace

4.5 Oct 5, 2020

A unique combination of expertise in many areas of intelligent digital product development, a theoretical background that enables them to build on the top of novel theoretical results, and at the same time, practicality of tireless focusing on the problems that matter to the end users and execution. About their expertise and theoretical knowledge, their CVs can tell you even more – but the mindset and being at the same time also “human and reachable” are the characteristics you don’t see often.

Software Development for International Consulting Firm

5.0 Jul 1, 2020

I like that they have a super-genius team of mathematicians and physics specialists. The Abelium team has a super high IQ and a strong team that knows what they are doing. They are more experienced, and they are 40 plus. I feel they are a much better fit for our needs; maybe we understand each other better and there isn’t as much of a generation gap between us.

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.
