UK-based housing and fintech platform – OneDome – has raised $25m in a pre-Series C funding round, taking its total capital raised to $40m as it accelerates growth across its integrated property and financial services platform.
The round was backed primarily by existing investors, alongside Channel 4 Ventures, whose participation was first announced in late 2025. The funding will be used to expand OneDome’s technology capabilities, advance product development, and support the continued rollout of its end-to-end digital homebuying platform.
The raise follows a period of rapid momentum for OneDome, which has emerged as one of the UK’s fastest-growing technology businesses. The company ranked fourth in the fintech category and 17th overall in 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 company in the Sunday Times Tech 100, reflecting revenue growth of over 4,000% between 2022 and 2025.
OneDome now arranges approximately $1.4bn in mortgage lending each month and works with a nationwide network of over 500 mortgage brokers, positioning it among the largest mortgage and property platforms in the UK.
“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.”

Founded to remove friction from the housing market, OneDome combines property search, mortgage origination, legal and transaction services, insurance and financial planning into a single digital journey.
Its flagship HomeBuyer Service packages the entire purchase process into a transparent, fixed-price model, reframing home ownership as a retail-style experience rather than a fragmented transaction.
Beyond the initial purchase, the platform supports customers across the full lifecycle of home ownership and personal finance. Backed by Channel 4 Ventures and family offices across the UK, Saudi Arabia, the United States and Australia, OneDome is using data and AI to replace manual processes with a more efficient, consumer-centric housing and mortgage ecosystem.
