Nous Raises $17M From Heartcore and Mosaic to Take Its AI Household Bills Agent Beyond the UK

Nous is registered with the Financial Conduct Authority and operates as an appointed representative of Stubben Edge & Partners, an FCA‑authorised firm.

Marsh says just under 250,000 UK households have signed up, and that Nous adds a household every minute. The company reports that it manages more than £685 million in annual household spending, an average of £2,765 per household, and that the average household saves £734.

The business has scaled by a factor of more than 20 in 12 months while keeping the same team size, according to Marsh. He did not say which metric grew 20‑fold or give a headcount.

More insurance products are in the pipeline, and Marsh said Nous would like to move a household's idle cash into higher‑interest savings accounts. The agent is being extended into further financial services as it moves into more regulated categories.

"We've spent the last 18 months building and refining an agent that not only feels magical but is in fact one that people can trust," Marsh said. "If you're going to be allowing an AI agent to make financial and purchasing decisions on your behalf, you need to know it's up to the job. That's why Nous is so focused on its vertical of household spending and admin and why we take safety and privacy so seriously."

Marsh also said UK households spend £1.7 trillion a year on things they pay for automatically and do not have time to think about, and that he believes more than half of that will be managed by agents within 10 years.

Max Niederhofer, general partner at Heartcore, said personal agents will transform the way people make household purchasing decisions and, through that, the economy, in ways that benefit the end consumer. He said the firm is excited about the work Marsh and his team are doing at the frontier of personal agents.

Toby Coppel, co‑founder of Mosaic, said what stands out is not only the growth rate but what sits behind it: people are trusting an agent to act for them and not just advise them, because it is built to be safe and does not rely on advertising. He said that is the shape Mosaic believes consumer AI will take.

Angel investors in the round include Tom Blomfield, of GoCardless and Monzo, Brent Hoberman, of Founders Factory, lastminute.com and Made.com, Doug Monro of Adzuna, Richard Moross of MOO, Angie Ma and Marc Warner of Faculty.ai, James Meekings of Funding Circle, Eamon Jubbawy and Husayn Kassai of Onfido, Will Dean of Tough Mudder and Daniel Hegarty of Habito.

Nous raised £6.6 million in seed funding in February 2022, led by Mosaic with more than 65 angels. With the new round, total disclosed funding is around $26 million.

Marsh worked at Index Ventures before founding onefinestay in 2009. AccorHotels bought onefinestay in 2016 for $200 million. He later lectured at Harvard Business School and started Nous in 2021 after returning to London. Hoberman was an early angel investor in onefinestay, and Heartcore's Niederhofer has known Marsh for 20 years.

The FCA's Mills Review found that 20 percent of UK adults are open to AI making financial decisions for them, with trust, control and access cited as key factors in whether people take that route.
