Problem
Brands spend budgets on marketplace advertising but don't own their audience. A buyer goes to Wildberries or Ozon — and disappears. No follow-up, no repeat touchpoints, no loyalty. And the user, in turn, has no easy way to know where to buy at the best price, and gets nothing for their brand loyalty.
Zetter solves both sides: the brand gets a direct Telegram channel with analytics and management, while the buyer gets a convenient price comparison tool and a loyalty program with real points.

Audience
| Role | Scenario |
|---|---|
| Brand manager / marketer | Launch a loyalty program without in-house development. Catalog management, campaigns, analytics — all through the admin panel. |
| E-commerce director | Monitor brand presence on marketplaces, compare prices, attribute purchases via receipts. |
| Growth / product manager | A/B tests via multi-bot system, cohort analysis, conversion funnels. |
| D2C brand owner | Direct communication channel with buyers in Telegram, without marketplace intermediaries and traffic fees. |

What's different
- Lives in Telegram — no need to download a separate app. The user is already there.
- Purchase verification, not self-reporting — points awarded only for real receipts with automatic recognition.
- Multi-bot out of the box — one deploy, multiple bots, separate analytics. Alternatives require separate instances.
- Prices updated automatically — hourly marketplace parsing, not manual entry.
- Full analytics without third-party BI — dashboard, cohorts, RFM, and funnels are built into the admin panel.
