OneDome, a London-based housing and FinTech platform, has raised £18 million in a Pre-Series C funding round, taking total funding raised to date to almost £30m.
The round was funded largely by existing investors alongside Channel 4 Ventures, whose investment was announced in late 2025.
The funding will be used to support the next phase of growth, including continued investment in technology, product development, and expansion of OneDome’s integrated housing and financial services platform.
The raise follows a period of strong momentum for the company. OneDome was ranked the fourth fastest-growing FinTech and 17th fastest-growing technology business in the UK by the Deloitte Fast 50 2025, based on 1,700% revenue growth between 2021 and 2024.
In 2026, the company was also named the sixth fastest-growing technology business by the Sunday Times Tech 100, having grown revenues by 4,066% between 2022 and 2025.
The platform currently arranges approximately $1.4 billion of mortgage lending per month and works with a network of over 500 mortgage brokers, making it one of the largest mortgage and property platforms in the UK.
Babek Ismayil, founder and CEO of OneDome, said: “Buying a home is still one of the most stressful and disjointed financial transactions people go through.
“We started OneDome to fix that by bringing everything under one roof and turning homebuying into a simple, transparent retail experience.
“This funding allows us to scale what is already a profitable and fast-growing platform, while continuing to challenge how homes are bought and financed in the UK.”
