Challenge

The agency ran on a rented CRM with no control over its database: owner phone numbers sat in plain view, listing presentations were made by hand, publishing to marketplaces took hours, and a departing broker could take clients with them.

Solution

Built the platform on Krayin CRM and n8n: 39 workflows, an AI assistant that creates a listing from a voice message, encrypted owner phones with reveal limits, automatic branded presentations and a client Mini App with a map and filters. Data from the previous CRM was migrated in full.

What was built

Migration of 545 listings and 402 contacts from the old CRM with data cleanup
Broker AI assistant in Telegram: listing from voice, message drafts, funnel hints
8 access roles, masked and encrypted owner phones, rate-limited reveal
A branded presentation page for every listing, watermarked photos
Client Mini App: list, map, cascading filters, listing card, dark theme
Lead kanban, commission and tax calculator, lead reactivation, bulk actions on the board
Publishing to OLX from each broker’s own account, listing import by link from OLX, rieltor and DOM.RIA
DOM.RIA market analytics: median price per m² versus competitors, weekly snapshot, duplicate filter (212 → 58 listings)
Valmont → Empire Group rebrand with zero downtime: new bots, profiles and avatars, a QR guide for marketing
