Challenge
Cosmass helps marketplace sellers decide by the numbers: how much they can pay for a product, where the break-even line is, and what the analytics for a specific product look like. The site had to show the tools right away and lead to registration.
Solution
We built a light website with soft gradients and colour-coded tool cards. The home page contains:
- First screen with a greeting and two buttons — a video about the platform and the content section
- Tool cards — a purchase-price calculator and a unit-economics calculator marked as free, plus product analytics marked as premium and connected to ZoomSelling.io
- “Use” and “Video” buttons on every tool
- Sign-in and registration and a UZ / RU switcher
- An “Ask a question” button linking to Telegram and a footer with quick links
- A compact menu on phones
Result
- A clear showcase of tools split into free and premium
- A short path from the home page to registration and a first calculation
- Two language versions and a responsive layout
