Nous raises $17M to put an AI agent in charge of your household bills

Nous, a London startup that uses an AI agent to run the tedious admin of a household, has raised $17M (about £12.8M) in a round led by Heartcore Capital, with existing backer Mosaic Ventures, Chalfen Ventures, Joyance Partners, Bain Future Back Ventures and a crowd of angels also taking part. It brings total funding to roughly $26M. Founded in 2021 by Greg Marsh — who previously built the hospitality company onefinestay — Nous says it now serves close to 250,000 UK households and tracks more than £685M of their annual spending.

Acting, not advising

What makes Nous interesting is the same thing that makes it risky: it does the work, rather than just surfacing it. Operating largely through WhatsApp, it will find a better energy tariff and switch you to it, cancel a subscription you have stopped using, chase a late refund, or book a repair — the household-finance equivalent of handing a capable assistant your admin inbox. It began life in 2023 as an OpenAI-powered tool that categorised and summarised your bills; the pitch now is an agent that takes action on your behalf.

That is squarely the direction we keep seeing across UK applied AI — PlannerPal doing it for financial advisers’ paperwork, InTouchNow answering GP surgery phones. Nous is the consumer-facing version, and arguably the one where “the AI did it for me” has to clear the highest trust bar, because the actions involve people’s money and contracts.

The caveats

Handing an agent authority over your bills raises obvious questions of consent, error and liability — if it switches you to the wrong tariff, who is responsible? Nous’s status as an FCA appointed representative is part of the answer, and worth watching as it expands into regulated insurance and financial services and beyond the UK. The “£685M of spending managed” figure is a reach-and-engagement metric, not revenue, and the money-admin space is crowded with apps promising to find you savings. But a consumer agent with a quarter of a million households already using it is past the demo stage, which is more than most “AI agent” pitches can say. The $17M is aimed at widening both the product and the map.
