agentOS

agentOS describes itself as a CRM that connects an agency to its proptech via open API, and that framing is the product’s argument. Rather than claiming to do everything, it positions itself as the system of record that other specialist tools plug into.

What It Does

• Estate agency: the sales pipeline
• Lettings: tenancy administration
• Property management: ongoing management of let stock
• Client accounting: rent and landlord payments
• Hybrid: explicit support for running third-party tools alongside the core modules
• Open API: the integration surface the product is organised around

Position

The open-API emphasis reflects a genuine split in this category. Some suppliers pursue a single system covering the whole agency, betting that integration cost exceeds the value of best-in-class components; others accept that agents will want Fixflo for repairs and a specialist referencing provider, and compete on how cleanly they connect. agentOS is firmly in the second camp, and lists Signable, Fixflo and DocuSign among its partners.

The company does not publish user or branch numbers on its homepage, so its scale relative to others in this directory is not something this entry can state.
