Marshmallow, the UK insurtech that built its reputation on fairer motor insurance pricing for underserved communities, has confirmed it now serves more than one million active policyholders. The milestone, reached in March 2025, cements the company's position as one of Europe's most valuable insurtech startups following its $85 million Series C round that valued the firm at over $1.25 billion. Co-founder Oliver Kent-Braham described the achievement as validation of the company's data-driven approach to risk assessment.

The London-based insurer is now preparing to move beyond motor insurance, with plans to launch home insurance products by the end of 2025. According to internal documents reviewed by FinBlockDaily, the company has been quietly building underwriting models for property risk using alternative data sources, including satellite imagery and IoT sensor data. Industry analysts at Oxbow Partners estimate the UK home insurance market is worth approximately £8.5 billion annually, offering significant headroom for a digital-first entrant.

Marshmallow's expansion comes at a time when traditional insurers are struggling with legacy technology and rising claims inflation. The company's loss ratio improved to 62 per cent in 2024, down from 71 per cent the previous year, suggesting its machine learning models are becoming increasingly accurate at pricing risk. "What Marshmallow has achieved is remarkable for a company that is barely seven years old," said Louise Sheridan, an insurance analyst at Berenberg. "The question now is whether they can replicate that success across multiple product lines while maintaining underwriting discipline."
