Nous, the London startup whose AI agent switches household bills and cancels subscriptions on its users' behalf, has raised $17 million to expand outside the UK. Heartcore Capital and existing seed investor Mosaic Ventures backed the round, alongside Chalfen Ventures, Joyance Partners and Bain Future Back Ventures, Tech.eu reported this morning. Angel investors include Monzo and GoCardless co-founder Tom Blomfield, Founders Factory's Brent Hoberman and Faculty co-founder Marc Warner, according to The Next Web. The company raised a $9 million seed round in 2022.

What Nous does

Nous was founded in 2021 by Greg Marsh, who previously co-founded the luxury home rental marketplace onefinestay, sold to Accor in 2016. The product left beta in 2025.

Once a household authorises it, the agent acts rather than advises. It finds cheaper car insurance, energy, broadband and mobile deals and switches the household over. It cancels unused subscriptions, fills in forms, and flags expensive contract terms and upcoming renewals. Newer features manage family calendars, send deadline reminders, find local tradespeople and book appointments.

Nous uses large language models for most tasks but switches to fixed rules for sensitive money decisions, which it says reduces errors. It is registered with the Financial Conduct Authority, so it can carry out regulated activities such as buying insurance. The company says it does not sell customer data or earn revenue from advertising, which it argues removes the conflict of interest that comparison sites have with the providers they list.

The numbers Nous reports

The company says almost 250,000 UK homes now use the service, with a new home joining roughly every minute, per The Next Web. It manages about £2,765 of each home's annual spending, more than £685 million in total, and says a typical household saves £734 a year on bills. These are Nous's own figures and have not been independently verified.

Marsh told Tech.eu the aim is "an agent that not only feels magic, but is also one people can actually trust", adding that when people hand financial decisions to AI, "you need to know it's up to the job". He also said most users are women, typically working mothers, and that the product is "not a toy for tech bros".

What the money is for

Over the next 12 months Nous plans to cover more spending categories, extend its regulated work into a wider range of insurance and other financial services, add tools for everyday household chores, and launch in other countries. It has not named which countries.

Marsh puts the size of the opportunity at £1.7 trillion a year in automatic payments made by British homes, he told The Next Web, and predicts that agents will manage more than half of that within ten years.

What this means for UK founders

The round lands a month after Meta launched its Muse personal agent and weeks after Instinct raised $1 billion at a $10 billion valuation, The Next Web noted, so the consumer agent category is now contested by both big tech and heavily funded newcomers. Nous's defence is regulatory: FCA registration and a rules-based layer for money decisions are slow to build and hard to copy, and they are what let it act on a household's behalf rather than just suggest.

It is also the second agentic AI round Chalfen Ventures has backed this month, after Opply's $7.5 million raise for an agent that buys ingredients for food brands. On the business side, Adfin raised $18 million for an agentic finance platform for UK SMEs earlier this year.

The open question is consumer trust. Bizztor's recent look at agentic commerce in the UK found only 6% of shoppers would let an agent buy on their behalf without checking. Nous's 250,000 households suggest that number moves once the agent is saving people money on bills they already pay, and that is the case it will need to make again in each new country.
