Founded 2025 · Dublin, Ireland
Lette, founded in Dublin in 2025, has raised a $6.5 million seed led by Peak to put AI agents in charge of leasing, resident support and maintenance for UK rental operators.
Peak leads a $6.5 million seed out of Dublin
Lette announced the round on October 27, 2026. Peak led it, with Heliad, Foreword VC, Pitchdrive and Adeline Arts and Science taking part, alongside Des Traynor, co-founder of Intercom, as an angel. Thijs Dijkman, general partner at Peak, spoke for the firm in the announcement.

The seed follows a $1.4 million pre-seed raised roughly a year earlier and takes the company to about $7.9 million in total funding. The money goes into the UK team, with hiring planned across product, engineering and customer operations, and into additional European markets in 2027. Mohan Sai, co-founder and chief executive, said the money buys depth in one market first. “We’re using this funding to go deeper for UK operators.”
Sai founded the company in March 2025 with Jakub Rajek, now chief product officer. Lette works out of offices in Dublin and London, and its team has grown sixfold over the past year, on the company’s own account.
Thirty thousand homes, one layer above Yardi
Lette runs AI agents across the rental lifecycle. The agents answer inquiries, book viewings, push a tenancy through to a signed lease, then stay on for resident questions, maintenance tickets, renewals, arrears and compliance checks. They sit on top of the property management systems operators already run, Yardi, MRI and RealPage among them, and write back into those systems.
The company says more than 30,000 homes run on the platform, and that its agents handle over 60 percent of resident support and maintenance requests. Both figures are self-reported and neither has been audited. Its named customers include urbeo, Ardstone, Grayling Properties and JLL, with build-to-rent and student accommodation the two formats it leans on.
Rajek described the product goal as taking repetitive administrative work off property managers. It is a narrow claim by the standards of AI pitches in real estate, and an operator can check it against a ticket queue.
A $1 billion European market growing at 6.9 percent
Europe’s property management software market was worth $1.04 billion in 2025 and is forecast to reach $1.76 billion by 2033, a compound annual growth rate of 6.9 percent over 2026 to 2033, according to Grand View Research. That is a small market set against the housing stock it serves. UK build-to-rent alone stood at 310,310 homes in Savills’ Q2 2026 count.
A category this modest keeps attracting seed capital because the spending it chases sits outside it, in the salaries of the people who answer the emails. The good news for a company like Lette is that software priced per unit captures only a sliver of what rental operations actually cost today, and the agents are priced against the headcount line, where the real money sits.
Our own records show the stage this round sits above. Vessla raised a €2.95 million pre-seed led by Seedcamp on October 19, 2026 for AI agents in property management, and Piney raised €1.6 million led by Uni.fund in September 2026 for short-term rental operations. At €5.85 million converted, Lette’s seed is the largest of the three, and the only one with a paying base above 30,000 units behind it.
Three rental-ops rounds in six weeks
Three European seed and pre-seed rounds in six weeks, all aimed at the same back office, is a pattern worth naming. European proptech spent a decade funding marketplaces and valuation tools, the layer that helps a building change hands. syte’s €9 million Series A in September 2026 for land and zoning analytics is that older thesis still working. What is getting funded now is the layer that keeps a building running after the deal closes.
Europe has a structural advantage here that we rarely count as one. Our rental markets are fragmented by national tenancy law, which has kept American property software from steamrolling the continent the way it did the US multifamily market. Every country is its own compliance problem. Imagine if that fragmentation, the thing European founders complain about most, turns out to be the moat that lets a Dublin company own UK and Irish rental operations before anyone in Texas has read the legislation.
Two things are worth watching over the next year. Whether that 60 percent resident-request figure holds as the unit count grows, since agent performance usually degrades with portfolio variety. And whether the 2027 European expansion starts in a market with tenancy law close to the UK and Ireland, or in one that forces a rebuild.
The goal was never to build Europe’s answer to the American property stack. It is to run the buildings we already have with fewer people stuck in an inbox, in markets nobody else wants to learn. Lette has 30,000 homes and one year to prove the second part. Let’s watch the number.
Lette’s profile and funding history sit on its Sesamers record, and every European round we track is in the fundraising data.
