Lottie snaps up CareMaster as AI push moves deeper into care operations

Lottie has bought CareMaster, a 25-year-old billing software provider for care businesses, in its second acquisition of a care software company. The London healthtech startup is pushing further into AI, and it’s aiming squarely at the dull, repetitive work that still sits underneath a lot of UK social care operations.

CareMaster brings a long track record in billing, payments and credit control, plus a customer base of nearly 75 care providers across more than 750 care home locations in the UK. That matters because these are the jobs that keep care businesses running, and they are also the jobs most likely to eat up time when teams are already stretched.

Lottie has been building in this space for four years. It acquired Found in 2022, when the care CRM served fewer than 100 care home locations. Since then, it has rebuilt that platform as AI-native and expanded it into home care and supported living. By the end of 2026, Lottie says Found will cover nearly 2,500 UK care services.

The company is now folding CareMaster’s base into Found and wants to use AI first on credit control, then across more of the customer journey, from a family’s first enquiry about care to the moment a provider gets paid. Lottie says the combined business should support £3 billion in annual invoicing by the first half of 2027. That would be up from more than £1 billion through Found today, with a projected £2 billion by the end of 2026.

The timing fits the sector. Social care is under pressure from rising demand, more complex needs, higher costs and staffing shortages, and the article makes clear that a lot of the pain is still administrative rather than clinical. Lottie’s bet is straightforward: take the paperwork, automate what can be automated, and leave the human work to humans. A rare case where the pitch is less “AI magic” and more “please stop making people do invoice chores by hand.”
