What agentOS does
agentOS is a UK-based vertical SaaS CRM platform serving estate agents, lettings agents, property managers, and landlords across the United Kingdom. The platform covers the full property lifecycle including sales, lettings, client accounting, property management, HMO and block management, compliance, and tenant-facing workflows. It is built on a .NET framework with a SQL database, hosted on Amazon AWS in Ireland, and exposed through a comprehensive V4 REST API with 16+ domain-specific endpoint sets. The product suite extends beyond the core CRM to include agentPay (payment processing), Calmony (FCA-regulated client bank accounts via Griffin and Modulr), the MyProp App (mobile portal for landlords and tenants), NegApp, a Payment App, an Open Banking integration via TrueLayer, and a Custom Web Application Suite of 100 PropTech plug-ins.
The business operates on a tiered subscription model with three core plans (£130/month Startup, £320/month Professional, £500/month Enterprise) plus per-seat pricing at £62.50/month for additional users. Revenue is diversified across SaaS subscriptions, API connector fees (£22.50/month per key), Open Banking connections (£22.50/month per account), verification checks, e-signature fees, professional services (£100-£150/hour), and an upcoming AI Agent User license (£62.50/month from February 2026).
