About

We don't make pretty sites — we make things that work.

We are a focused studio of strategists, designers and engineers. Every project starts with clarity — who it's for, what it needs to do, how success looks. Design follows function, not the other way around.

Our clients are companies building for real markets — Russian, European, global. We work in both languages, across time zones, and with full technical accountability.

Everything included. Nothing hidden.

Every package comes with a defined scope of deliverables. You get real documentation, real assets, real transfer of ownership. No vague retainers, no locked-in platforms.

01 Site Structure
+
Sitemap, hierarchy, internal linking — built before design. Every page has a purpose, every link has a strategy.
02 Interface Design
+
All screens in Figma: desktop, tablet, mobile. Delivered as a structured file with components, styles and page variants.
03 Mobile Version
+
Separate layout for thumb navigation, not a scaled desktop. Every interaction reviewed for mobile ergonomics.
04 Integrations
+
CRM, analytics, forms — connected and tested before launch. No manual wiring after handoff.
05 SEO Launch Setup
+
Meta, sitemap, robots.txt, structured data — day one ready. Not afterthought SEO, foundation SEO.
06 Post-Launch Support
+
30 days fixes included. Growth retainer available after — monthly sprints to improve what the data shows.
