What clients say

We came to Krelix with an idea for an educational platform — and got a finished product that exceeded our expectations. The team deeply immersed themselves in EdTech specifics and proposed solutions we hadn't even considered. The speed was impressive: from the first call to launch took less than two months.

Stepan Melekhin

We needed a website that works across two regions — Russia and Kyrgyzstan. Krelix built a unified system with two domains and configured SEO for each market. Leads grew significantly, and now any manager can manage content through the CMS without a developer. I recommend them to anyone who values results.

Irik Valiev

Krelix developed an admin panel for us that completely automated routine processes. Previously, generating reports took an entire day — now it takes minutes. I especially appreciate the attention to UX detail: the interface is intuitive, and we train new employees in half an hour.
