Company is Kyiv based, and my team worked through the Russian invasion without downtime, and I'd chat with reps who were working in the dark on hotspots while rockets and helicopters were flying overhead.

Market Research for Tax Consultancy Firm

4.0 Jun 22, 2021

AI Bees is more B2C-focused, but they’ve adapted to work in a B2B model. There has been an upturn in the last six months, and they’ve since become accustomed to working at a very professional level with my team. Their services are meant for short-term material projects and not for large, long-term projects, but AI Bees has been very willing and able to learn. They’ve improved greatly and are good listeners; we give weekly feedback and they adjust their methods accordingly. AI Bees is very flexible and ready to learn. They’re able to listen to what partners are telling them and take the necessary risks to improve. What they’re doing is better than being rigid and not able to change in the long run.

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.
