OneDome secures £18.3m to simplify homebuying via mortgage broker network
This article covers OneDome, a London fintech startup, which has raised £18.26m in a growth funding round, taking total capital to about £29.2m. The funding is intended to deepen its technology and product work and to expand its integrated housing and financial services platform, affecting mortgage brokers, homebuyers and the UK housing market.
OneDome, a London fintech startup, has raised £18.26m in a growth funding round, taking total capital raised to about £29.2m. The company says the fresh funding will be used to deepen its technology and product work and to expand its integrated housing and financial services platform.
Why it matters
OneDome operates at scale in the UK housing market, arranging roughly £1bn of mortgage lending a month through a network of more than 500 mortgage brokers. That reach, combined with reported profitability and rapid revenue growth, means the business could materially affect how home purchases are brokered and financed if it continues to convert platform reach into consumer-facing products.
The company has also been recognised for fast growth: Deloitte Fast 50 placed it among the fastest-growing fintech and technology businesses in 2025, and the Sunday Times Tech 100 ranked it highly in 2026. Those awards reflect rapid revenue gains over multiple years rather than marketing claims about market dominance.
Inside the product
OneDome describes itself as an integrated housing and fintech platform that stitches together property search, mortgage origination, legal and transaction services, insurance and financial planning. Its HomeBuyer Service is presented as a fixed-price, end-to-end offering intended to remove friction from home purchases, while the wider platform aims to support customers across the lifecycle of home ownership.
The company also highlights AI capabilities to personalise and streamline decision points; however, independent details on specific AI models or performance metrics were not disclosed in the announcement.
Who are the investors?
The round was funded largely by existing backers alongside Channel 4 Ventures. The announcement also refers broadly to family offices in the UK, Saudi Arabia, the United States and Australia as part of OneDome’s investor base. Channel 4 Ventures’ participation was separately noted as having been announced in late 2025.
The funding, taking the company’s total to about £29.2m, is earmarked for technology and product development and for scaling the platform’s integrated housing and financial services capabilities.

Founder perspective
In the announcement, Babek Ismayil, Founder and CEO at 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.
That comment frames the company’s mission around reducing transaction friction and combining multiple services under one digital experience. The firm positions profit and growth as validation of its approach, though external verification of profitability and unit economics was not included in the release.
The bigger picture
The raise underlines continued investor interest in digital mortgage origination and end-to-end homebuying platforms as incumbents and startups look to simplify a traditionally fragmented customer journey. The deal also reflects sustained appetite from fintech investors for propositions that can aggregate distribution (such as broker networks) with direct consumer services.
For the UK and European ecosystem, OneDome’s financing is another data point in the maturing fintech landscape where revenue traction and route-to-market via partners are becoming as important as headline technology. If the company successfully scales its product across more brokers and consumers, it could influence how mortgage and property services are packaged and sold across the market.
