London-based Nous, an AI agent for household bill management, has secured $17 million in a funding round led by Heartcore Capital and Mosaic Ventures. Additional participants included Chalfen Ventures, Joyance Partners, and Bain Future Back Ventures. The company has now raised a total of approximately $26 million since its founding in 2021.

The platform currently serves just under 250 000 UK households, adding one new household every minute. Users manage over £685 million in annual spending through the service, with an average household expenditure of £2 765. According to the company, the average user saves £734 annually.

The AI agent automates tasks such as finding deals on energy, broadband, and insurance, as well as managing subscriptions and scheduling appointments. Nous is FCA-registered and operates as an appointed representative of Stubben Edge and Partners. The company plans to use the new capital for international expansion and to enter additional product categories.

Founder Greg Marsh previously established onefinestay, which was sold to AccorHotels for $200 million in 2016. The startup also attracted angel investment from notable figures including Tom Blomfield, Brent Hoberman, and the founders of Onfido and Faculty.ai. The business reports that it has scaled by a factor of more than 20 over the past 12 months.
