Marshmallow vertically integrated B2C insurer

This setup means Marshmallow keeps both the customer relationship and the underwriting economics, which is why it can price aggressively for new to UK drivers without handing most of the upside to a carrier partner. The customer gets a quote, uploads foreign driving history and proof documents, buys in app or on web, and stays inside the same system through policy servicing and claims, while Marshmallow writes risk through its own carrier and sells through its FCA regulated broker.1 2 3 4

• Vertical integration matters because many insurtechs stop at the MGA layer and earn distribution fees while outside carriers keep the float and much of the underwriting margin. Marshmallow instead combines broker distribution with carrier balance sheet economics, closer to Lemonade’s full stack model than to a pure software enabled broker.3 5 6
• The B2C model is unusually direct for UK motor insurance. Marshmallow acquires drivers itself, mostly people new to the UK, then uses its own quote flow to accept foreign licences, overseas no claims proof, and additional documents that legacy comparison led underwriting often handles poorly or rejects outright.2 4 7 8
• Owning the whole loop also makes the niche defensible. Every quote, document check, policy, and claim adds more data on thin file migrant drivers, which improves pricing for the next cohort. That helps explain how the company reached an estimated $370M of 2024 revenue and profitability while still undercutting incumbents on price.2 3

From here, the same structure should let Marshmallow stretch beyond car insurance into more products for the same customer base, and into other migrant heavy markets. If it keeps compounding proprietary risk data while cross selling financial products, the company starts to look less like a niche broker and more like a specialized consumer financial institution built around underwriting.2 3 9
