Estatger — Real Estate SaaS Platform
Building a complete real estate SaaS platform with AI-powered property search, CRM pipeline, embeddable listings, and multi-tenant agency management.
Summary
Estatger is a comprehensive SaaS platform for real estate agencies in Spain. It combines three products agencies typically buy separately: a professional property search engine embeddable into any website, an internal ERP/CRM with lead pipeline and deal tracking, and an AI assistant trained on each agency's inventory. Built for multi-tenancy — one company can manage multiple agencies with isolated data. The platform serves agencies of all sizes, from independent agents to large franchised networks.
