Lette raises $6.5M to put AI agents to work on UK rentals — 60% of resident requests already automated
London-based Lette has raised a $6.5 million seed round led by Peak to scale its AI operating system for rental operators, which it says already handles over 60% of resident support and maintenance requests across some 30,000 units.
- Who: Lette, a London-based AI platform for residential rental operators, founded in 2025 by Jakub Rajek and Mohan Sai.
- What: a $6.5 million seed round announced on October 27, 2026, led by Peak.
- Investors: Heliad, Foreword VC, Pitchdrive and Adeline participated, alongside angel investor Des Traynor, co-founder of Intercom.
- Traction (company claim): across some 30,000 units, Lette says it handles over 60% of resident support and maintenance requests automatically, and has cut leasing time from two weeks to under four days.
- What’s next: grow the UK team across product development, engineering and customer operations, and enter additional European markets in 2027.

The round#
Lette, a London-based startup building an AI operating system for residential rental operators, has raised $6.5 million in seed funding. The round was led by Peak, with participation from Heliad, Foreword VC, Pitchdrive and Adeline, alongside angel investors including Des Traynor, co-founder of Intercom.
The company says the money will fund growth of its UK team, with hiring across product development, engineering and customer operations, and expansion into additional European markets in 2027.

What the platform does#
Founded in 2025 by Jakub Rajek and Mohan Sai, Lette sells to operators in the UK and Ireland across build-to-rent, private rented, student accommodation and single-family housing. Its AI agents handle work across the rental lifecycle, from first enquiry and leasing through resident support, maintenance, rent arrears and compliance.
The platform is designed to sit alongside the property management software operators already use, rather than replace it. Residents reach it through an AI-powered app, email, WhatsApp, SMS and voice calls, with responses around the clock and in multiple languages. Sai, Lette’s co-founder and chief executive, describes the pitch in one line: “Lette takes a home from first enquiry to signed lease and stays with the resident after move-in, working alongside the systems operators already have.”
Rajek, the company’s chief product officer, said the aim is to strip out repetitive administrative work so property managers can spend more time on direct interactions with residents.
Why now: empty homes have become expensive#
The timing is tied to a shift in English rental law. Since the Renters Rights Act came into force in May, ending fixed-term tenancies in England, residents can leave at two months’ notice — which makes tenant retention, and every day a home sits empty, more costly for operators.
Sai put it bluntly: “Now that residents can leave at two months’ notice, every day a home sits empty is lost rent, and that is what we help operators win back.”

The numbers — and what they don’t say#
Lette says its technology is used across thousands of residential units, and its customer base includes real estate services firm JLL and large financial institutions. Across some 30,000 units, the company says it already handles over 60% of resident support and maintenance requests automatically, and claims to have cut the time it takes to lease a home from two weeks to under four days.
Those figures are Lette’s own: the funding announcement gives no valuation, revenue figure or independent verification. What it does show is where the next wave of applied AI agents is landing — not in flashy consumer demos, but in the unglamorous operational middle of industries like housing, where a faster lease and an answered maintenance request translate directly into rent collected.
