London's Nous raises $17m for an AI agent that runs household bills

Nous, a London startup that builds an AI agent to manage household bills and admin, has raised $17 million in new funding, the company said in a blog post on 26 October 2026. The money comes from Heartcore Capital and existing seed investor Mosaic Ventures, with participation from Chalfen Ventures, Joyance Partners and Bain Future Back Ventures. Sifted and Tech.eu report that Heartcore led the round.

The company says nearly 250,000 UK households now use Nous and that another one signs up every minute. It says it manages more than $900 million of household spending a year; Tech Funding News gives the figure as more than £685 million.

What Nous does

Nous calls itself a household AI agent. According to the company, the agent makes decisions and takes action for a household instead of only sending reminders or recommendations. It finds cheaper deals on energy, broadband, mobile and car insurance, does the switching, cancels subscriptions, fills out forms and flags contract terms and renewal traps. It can also manage family calendars, find local tradespeople and book appointments.

Nous says it saves a typical household £734 a year across its bills. That figure comes from the company. Users choose how much control they hand over; founder and CEO Greg Marsh told Tech Funding News that most pick a "balanced mode", in which Nous tells the household about planned actions so it can opt out or change them.

The company is registered with the UK Financial Conduct Authority and, according to Tech Funding News, operates as an appointed representative of an FCA-authorised firm. Nous says it does not rely on advertising, and The Next Web reports that it combines large language models with rules-based logic for money decisions.

The founder's path

Marsh is a repeat founder. He worked at Index Ventures before co-founding the London home rental company onefinestay in 2009, which AccorHotels bought in 2016. He later lectured at Harvard Business School, returned to London and founded Nous in 2021 with co-founders including Glen Walker and Jon Rudoe. Nous announced a $9 million seed round led by Mosaic Ventures in February 2022, according to its blog, which puts total disclosed funding at about $26 million.

"We've spent the last 18 months building and honing an agent that not only feels magic, but is also one people can actually trust," Marsh told Tech.eu. "If you are allowing an AI agent to make financial and purchasing decisions on your behalf, you need to know it's up to the job."

Who is backing it

Max Niederhofer, General Partner at Heartcore Capital, said: "Personal agents will transform the way we make household purchasing decisions and thus transform the economy in ways that benefit the end consumer."

Toby Coppel, General Partner at Mosaic Ventures, said people are "trusting an agent to act for them, not just advise them, because it is built to be safe and doesn't rely on advertising." He added that Mosaic is backing Nous "as it moves into more regulated categories and beyond the UK."

Angel investors include Tom Blomfield (GoCardless and Monzo), Brent Hoberman (Founders Factory, lastminute.com and Made.com), Marc Warner, Angie Ma and Andrew Brookes (Faculty), and Onfido co-founders Eamon Jubbawy and Husayn Kassai, among others.

What the money is for

Nous says that over the coming year it plans to move into more regulated activities, including a broader insurance remit and additional financial services. It also wants to add more everyday chores to what the agent can handle, and to expand internationally beyond the UK. It has not named target countries.

Marsh argues that the market is large. He told The Next Web and Tech Funding News that UK households spend £1.7 trillion a year on things they pay for automatically, and that he expects agents to manage more than half of that within ten years. That is his forecast, not a market estimate from a third party.

What it means for European founders and investors

Most European AI agent funding so far has gone to business software, from enterprise operations, as in Duvo's $32m Series A, to legal work at Legora. Nous is a consumer test of the same idea: will people let software act on their money, not just advise them?

Its answer so far is a narrow focus on one area, household spending and admin, and a regulated set-up rather than an ad-funded model. The challenge is distribution. Large AI assistants and banks are moving towards the same customers, and expansion outside the UK will mean new suppliers, new rules and new switching processes in each market.

For founders building consumer AI in Europe, the round shows that investors will fund agents that act, as long as they can show trust, regulation and real savings. Context on the wider funding climate is in our report on European tech funding in Q3 2026.
