UK Care Software Consolidation: Lottie Acquires CareMaster to Build Integrated Back-Office Platform

London-based healthtech company Lottie has acquired CareMaster, a legacy care billing software provider serving approximately 75 UK care organizations across 750 locations, to address administrative inefficiencies in the adult social care sector. The transaction represents Lottie's second major acquisition and aims to integrate CareMaster's billing expertise into its cloud-based operating system, automating invoicing processes for the fragmented UK care economy. The combined entity plans to expand its managed annual invoicing volume from £1 billion to £3 billion by mid-2027.

Lottie's integration strategy reflects a deliberate shift from its original marketplace model toward becoming a comprehensive operational backbone for UK care providers. The company's first acquisition of Found in 2022 introduced artificial intelligence capabilities for managing inquiry workflows and occupancy management, establishing a foundation for broader administrative automation. CareMaster's addition of specialized billing infrastructure—encompassing multi-payer invoicing, resident accounting, and legacy system integration—closes a critical gap in the fragmented care sector's financial operations.

The scale of the combined platform underscores the fragmentation that characterizes UK adult social care. Currently managing over £1 billion in annual invoicing across 2,500 care services, the partnership aims to triple this volume by mid-2027, suggesting substantial market consolidation potential. CareMaster's 25-year presence and established relationships with 75 provider groups provide immediate market penetration that would otherwise require years to develop independently.
