Founded 2021 · London, United Kingdom
Nous, the London company whose AI agent runs household bills over WhatsApp, has raised $17 million led by Heartcore Capital, with seed investor Mosaic Ventures backing it again, to move into insurance and out of the UK.
$17 million led by Heartcore, with Mosaic back in
Nous announced the round on 26 October 2026. Heartcore Capital led it and Mosaic Ventures, which led the company’s seed in February 2022, came back in (Sifted, 26 October 2026). Chalfen Ventures, Joyance Partners and Bain Future Back Ventures took part. No stage label travels with the announcement, so this is a round and the company has not called it anything narrower.

The angel list runs straight through British consumer fintech. Tom Blomfield of Monzo, Brent Hoberman and Marc Warner are among the names, alongside angels out of GoCardless, Founders Factory and Onfido (The Next Web and Tech.eu, 26 October 2026).
Nous raised £6.6 million at seed in February 2022, led by Mosaic alongside more than 65 angels, which puts total disclosed funding at about $26 million (Tech Funding News, 26 October 2026). The new capital goes into more spending categories, a wider range of insurance and other regulated financial services, tools for everyday household chores, and launches in other countries inside the next year.
A onefinestay founder’s second company, delivered over WhatsApp
Nous was founded in 2021 by Greg Marsh, who co-founded the luxury rental marketplace onefinestay, and is registered in the UK as Nous for your House Limited. The agent watches a household’s energy tariff, broadband contract, insurance renewals and subscriptions, switches or cancels when the numbers say so, books repairs, chases refunds, and reports back over WhatsApp instead of an app nobody opens.
Just under 250,000 UK homes have signed up, with a new one joining roughly every minute, and the agent now sits across more than £685 million of annual household spending, about £2,765 per home. The company says a typical household saves £734 a year on its bills and that it has scaled by a factor of more than 20 in twelve months (Tech Funding News, 26 October 2026). Those are the company’s own figures and nobody independent has audited them.
Marsh is blunt about who is actually using it. “This isn’t a toy for tech bros,” he said. “The vast majority of our users are women, typically working mums.” (The Next Web, 26 October 2026)
A £2.1 billion comparison market growing 2.7% a year
The incumbent here is the price comparison website. That UK industry turned over about £2.1 billion in 2026 and grew at a 2.7% compound annual rate over the five years to 2026 (IBISWorld, August 2026). It is large, profitable and slow, and it rests on one assumption, that households will do the comparing themselves, once a year, when they remember.
The category Nous sits in moves at another speed entirely. The global AI agents market was worth $11.55 billion in 2026 and is forecast at $294.66 billion by 2035, a 43.57% CAGR (Precedence Research, updated July 2026). Those two growth rates, 2.7% and 43.57%, are the investment case in two numbers.
On scale, $17 million is about €15.2 million at the mid-market rate on 26 October 2026 (XE). In our own fundraising data that sits between Duvo’s €28.5 million Series A, led by Balderton Capital on 14 October 2026, and Vessla’s €2.95 million pre-seed, led by Seedcamp on 19 October 2026. Both of those sell agents to businesses. Nous sells one to a family.
Who is willing to let an agent spend their money
Look at where European agent money went this year and almost all of it is enterprise. Our applied AI and agents funding desk reads as a list of companies selling to procurement teams, IT departments and property managers. The reality is that consumer AI has been the harder sell, because trust is the product and a wrong switch costs a real household real money.
The good news is that Nous has an answer which does not depend on the model being clever. It picked one vertical, household spending and admin, and stayed inside it for five years. Toby Coppel of Mosaic put the change in terms of permission, saying people are now trusting an agent to act for them, where before they asked it for advice (Tech Funding News, 26 October 2026). A quarter of a million British households handing over their tariffs is the first European evidence at any real scale that they will.
Two things are worth watching from here. The first is regulation. Moving into wider insurance and financial services puts an autonomous agent inside FCA-supervised territory, and nobody in Europe has yet settled what a regulated agent acting on a customer’s behalf is allowed to do unsupervised. The second is geography. The UK has one of the most liquid switching markets on the continent. Imagine if the economics that work in Britain simply do not transfer to Germany or France, where tariff churn is a fraction of the British rate.
What we are seeing is a European consumer company funded by European investors, Heartcore in Copenhagen and Mosaic in London, with no American growth fund anywhere in the sentence. Remember: the hard part of consumer AI was never the model, it was the permission. Watch which country Nous opens first, and watch whether that £734 holds when it gets there!
