Lette, a Dublin-headquartered proptech startup developing an AI-powered operating system for residential property management, has raised $6.5 million in seed funding led by Peak. The round included participation from Heliad, Foreword VC, Pitchdrive and Adeline Arts and Science, alongside angel investors including Des Traynor, co-founder of Intercom.
Founded in 2025 by Mohan Sai, CEO, and Jakub Rajek, Chief Product Officer, Lette develops AI software for institutional residential property operators across the UK and Ireland. Its platform serves build-to-rent, private rented, student accommodation and single-family housing portfolios.
Lette’s AI agents automate operational workflows throughout the residential rental lifecycle, including tenant enquiries, property viewings, lease administration, resident communications, maintenance coordination, rent arrears and compliance-related tasks. The platform integrates with existing property management systems, enabling operators to automate processes without replacing their core software infrastructure.
According to the company, its technology supports more than 30,000 residential units and automatically handles over 60% of resident support and maintenance requests. Its customers include real estate services company JLL and financial institutions operating residential property portfolios.
The new funding will support Lette’s expansion in the UK, including recruitment across product development, engineering and customer operations. The company also plans to enter additional European markets in 2027.
The seed investment follows a $1.4 million pre-seed round announced in October 2025, led by Pitchdrive, with participation from Baseline, Lugus Capital and angel investors including Conor Sheridan and Mark Ransford.
