Lette raises $6.5M to scale AI automation for UK rental operators

Lette has raised $6.5 million in seed funding to expand its AI platform for residential property operators. Peak led the round, with Heliad, Foreword VC, Pitchdrive and Adeline also backing the company, plus angel investors including Des Traynor, the Intercom co-founder.

The company, founded by Jakub Rajek and Mohan Sai, is building what it calls an AI operating system for rental housing in the UK and Ireland. Its focus is the messy middle of property management: leasing, resident communication, maintenance requests, rent arrears and compliance, all of it still too often handled through emails, spreadsheets and scattered tools.

Lette’s pitch is not to rip out existing software. The platform sits alongside current property management systems and uses AI agents to automate work across the rental journey, from the first enquiry to the signed lease and beyond move-in. It handles messages through an app, email, WhatsApp, SMS and voice calls, and it does that around the clock in multiple languages.

The company says its system is already being used across thousands of residential units. Customers include JLL and large financial institutions, and Lette claims the software is helping operators cut leasing time, manage resident support and maintenance more efficiently, and keep larger portfolios under control without adding staff at the same pace.

The new money will go into expanding the UK team, with hiring planned across product development, engineering and customer operations. Lette also plans to enter additional European markets in 2027.
