Our take
Debt is a major issue in the UK, with over 300 people declared insolvent every day and millions of households struggling with low savings or lacking basic appliances. Yet, debt collection practices haven't changed much in a century.
Ophelos launched in 2021 to fix that, and by 2023, it was acquired by Interum, Europe's largest credit management firm. The team brings experience from top companies like Monzo, Google, and IBM, and works closely with leading universities to drive innovation in finance and AI.
Ophelos is redesigning how debt is handled, using a digital-first, AI-driven approach that helps people pay off debt affordably while giving businesses smarter insights. And clients like Octopus Energy and Scottish Power are already using their platform to improve the customer experience.
Backed by top investors and now part of Interum, Ophelos has expanded into 17 European markets, scaling its missions to make debt recovery fairer and more human.
