Affinia acquires Cambridge-Based Green & Purple to expand outsourced finance capabilities
18.12.25

Affinia, the challenger accounting, tax and business advisory group backed by Sovereign Capital Partners, has acquired Green & Purple, a Cambridge-based outsourced finance services and accounting practice. This strategic acquisition further strengthens Affinia’s footprint in a core growth region, and adds fractional CFO and outsourced finance capabilities to its client service offering.
With a team of over 40 professionals, Green & Purple provides virtual finance team and CFO services to more than 400 clients across the Cambridge and London areas. The firm specialises in monthly bookkeeping, management accounts, payroll, and strategic CFO/FD advisory services for high-growth sectors including technology, life sciences, creative and media, and consultancy.
This acquisition enhances Affinia's service portfolio, enabling the Group to offer integrated finance leadership and operational support alongside its core accounting, tax and advisory services, creating additional value for clients across the network.
Sovereign invested in Affinia's founding firm, LB Group, in May 2023 and has since partnered with the management team on an extensive Buy & Build strategy to create a challenger in the accounting, tax and business advisory sector. Green & Purple is the latest business to join the Group, and follows the recent additions of Opass Billings Wilson & Honey based in Kent, Richmond accounting firm PK Group, and Cambridge’s Business Partners.
Alex Hay, Partner, Sovereign Capital Partners, said: “The acquisition of Green & Purple is a clear demonstration of Affinia’s commitment to building a market-leading platform. Their expertise in outsourced finance and virtual CFO services adds real depth to Affinia’s offering and brings a high-quality client base in Cambridge and London. This partnership will unlock considerable opportunities for growth, innovation, and value creation for both clients and colleagues.”
