Try Dealroom → and Future Back VenturesDealroom has a profile for this one. Try Dealroom →. The London startup builds an AI agent that takes over household admin outright — switching energy, broadband, mobile and car-insurance providers, cancelling subscriptions, filling in forms and managing family calendars — rather than just sending reminders.
Why now? Greg MarshDealroom has a profile for this one. Try Dealroom → founded Nous in 2021 after previously co-founding and running onefinestay until its sale to AccorDealroom has a profile for this one. Try Dealroom → in 2016. Nous raised a $9 million seed round in 2022 and left beta in 2025; it says almost 250,000 UK households now use the agent, which manages more than $900 million of combined household spending and saves a typical household £734 a year on bills.

What they're saying: "We backed Nous at seed, and in eighteen months Greg and the team have gone from beta to a quarter of a million households handing over real spending decisions, with a new home joining every minute," said Toby CoppelDealroom has a profile for this one.

Try Dealroom →, 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." Marsh pushed back on the idea Nous is a novelty: "This isn't a toy for tech bros. The vast majority of our users are women, typically working mums, who have to carry much of the mental load for their household."
Why it matters: The raise lands as investor money piles into AI agents, though the biggest cheques so far have gone to general-purpose or enterprise players — Meta launched its Muse personal agent in September, and weeks later Instinct raised $1 billion at a $10 billion valuation. A $17 million round is modest by comparison, but it signals dedicated capital is also forming around narrower, consumer-facing agents built for a single job rather than general-purpose assistants.
