Revenue
Sacra estimates that Marshmallow generated £289.4M (about $369.9M) in revenue in 2024, a 62% increase year-over-year from £184.1M (about $229M) in 2023. This growth is attributed to the company's expansion from serving 100,000 drivers in 2021 to over 1 million insured drivers by 2024, leveraging the UK's record immigration flows and favorable motor insurance pricing cycles.
The revenue increase coincided with a shift in profitability, as the company moved from a £0.2M net loss in 2023 to a £20.3M net profit in 2024, reflecting a 7.0% net margin. This shift was driven by scale efficiencies in underwriting operations and hard market conditions that supported premium pricing in UK motor insurance throughout 2024.
Marshmallow's compound annual growth rate from 2021 to 2024 was 93.1%, supported by its expansion into van coverage and ancillary services beyond core motor insurance. The company's gross margin rose from 21.2% in 2023 to 25.5% in 2024, reflecting improved claims performance and reinsurance economics as its proprietary risk models advanced.
Valuation
Marshmallow raised $90 million in a Series C round in April 2025, bringing total funding to approximately $220 million. The round was led by Portage Capital, with participation from BlackRock and Columbia Lake Partners.
Previous investors in earlier rounds include Passion Capital, Investec, and Scor. The Series C round combined equity and debt financing, allocating capital for international expansion and product development beyond the company's UK motor insurance business.
Product
Marshmallow is a digital car insurance platform focused on drivers who have recently moved to the UK, leveraging alternative data sources to price risk more accurately for immigrants without traditional UK credit or claims history.
The user experience begins with a fully digital quote process, where customers answer approximately 30 questions via web or mobile interfaces. Unlike traditional insurers, Marshmallow's system accepts foreign license numbers, overseas no-claims documentation, and scanned copies of non-UK proof of address. Its proprietary underwriting engine integrates a database of over 1 million migrant driver risk records with external data feeds from the DVLA, credit bureaus, optional telematics data, and computer vision-powered document fraud detection.
Within three minutes, users can select between two product tiers: Marshmallow Original, which includes comprehensive coverage with courtesy cars, European coverage, breakdown assistance, and legal protection, and Marshmallow Essential, a lower-cost option introduced in 2024 for price-sensitive customers. Policy management is handled entirely through the mobile app, enabling users to access proof of insurance, make policy changes, and update addresses without incurring administrative fees.
Claims processing is designed as a digital-first system, offering 24/7 first notice of loss reporting, photo uploads for damage assessment, and repair appointment scheduling with progress tracking. The platform also includes the Perks ecosystem, which provides discounted mobile servicing through ClickMechanic partnerships, credit-building cards, remittance discounts, and gym memberships, designed as part of a broader settling-into-the-UK package.
Business Model
Marshmallow operates as a vertically integrated insurer with a B2C go-to-market model, managing the entire value chain from customer acquisition to claims settlement through its Gibraltar-licensed carrier, Marshmallow Insurance Limited, and UK-regulated broker, Marshmallow Financial Services Limited.
The company generates revenue through traditional insurance premiums and fees, with the majority derived from earned premiums within its carrier operations. Its pricing model uses proprietary alternative data scoring to offer premiums 15-40% lower for migrant customers compared to traditional insurers, while maintaining profitable risk selection through machine learning models trained on an expanding database of thin-file driver performance.
Marshmallow's cost structure benefits from digital-first operations that eliminate traditional call centers and paper-based processes. Administrative expenses are projected to account for approximately 21.5% of turnover in 2024. Operational leverage is achieved through a Hungary-based service center, and the company owns Marshmallow Repair Limited to directly manage claims costs, reducing reliance on third-party repair networks.
The reinsurance strategy includes quota-share arrangements with a single primary reinsurer for proportional risk transfer, supplemented by excess-of-loss coverage distributed across multiple reinsurers. This approach enables retention of underwriting profits while limiting capital requirements, though it introduces concentration risk tied to the primary reinsurance relationship.
The business model incorporates a data feedback loop, where each new customer enhances risk models for future pricing. Vertical integration, from carrier licensing to repair networks, allows the company to capture margin at each stage of the value chain, avoiding fees typically paid to third-party providers.
Competition
Vertically integrated insurtech players
Zego became profitable in 2025 as the first UK insurtech with a carrier license, focusing on gig economy and commercial van drivers through proprietary telematics and rating engines. INSHUR transitioned from managing general agent (MGA) to full-stack carrier with Lloyd's syndicate backing, targeting private-hire and delivery drivers using machine learning risk scores derived from ride-hail platform data. Both competitors highlight the financial and operational benefits of owning a carrier license for margin capture and underwriting control, an area where Marshmallow remains behind despite its Gibraltar licensing.
Digital-first incumbent brands
Flow from Allianz and Quotemehappy from Aviva utilize parent company balance sheets to offer zero-call-center, app-only policies, potentially achieving lower reinsurance costs than independent players. DirectLine's return to price comparison websites after years of absence reflects incumbents' readiness to compete more aggressively on digital channels. These brands may undercut Marshmallow on price during soft market cycles while replicating its digital user experience, reducing differentiation based on convenience and technology.
Usage-based and flexible pricing specialists
Cuvva provides hour and day policies with monthly subscription options targeting customers with non-traditional insurance histories, while By Miles offers pay-per-mile annual coverage for low-mileage urban drivers, a segment that overlaps with Marshmallow's migrant customer base. These competitors focus on specific use cases within Marshmallow's target market, potentially capturing the most profitable customer segments through specialized pricing models that traditional annual policies cannot address.
TAM Expansion
New product categories
Van insurance, launched in 2024, applies Marshmallow's actuarial models to the 3.9 million UK commercial vans, a market representing £5 billion in gross written premiums and adjacent to personal motor insurance. Home insurance pilots, planned for 2025, utilize address-level risk data already collected for auto policies. Additionally, the company's first lending product, expected in late 2025, will establish Marshmallow as a credit underwriter for thin-file migrants, targeting the £10-12 billion UK newcomer consumer credit market.
Customer base expansion
The van insurance product is designed to attract UK-born sole traders, expanding Marshmallow's customer base beyond the new-to-UK segment. The company's proprietary migrant data graph, which includes visa categories, foreign driving history, and identity documents, can be repurposed to price additional risk lines such as renters insurance and remittance users without materially increasing customer acquisition costs. Growth from 100,000 to over 1 million insured drivers demonstrates the scalability of their scoring models beyond the initial immigrant-focused market.
Geographic expansion
The recent $90 million funding round allocates capital for international market entry, with near-term targets including Ireland, Spain, and Germany. These markets feature significant migrant inflows and benefit from EU-wide motor insurance passporting enabled by Marshmallow's Gibraltar license. The Gibraltar-domiciled carrier structure facilitates access to continental European markets post-Brexit, potentially through acquisitions of local MGAs or fronting carriers to expedite licensing.
Risks
Reinsurance concentration: Marshmallow relies on a single quota-share reinsurer for proportional risk transfer, creating counterparty risk if the relationship ends or pricing terms worsen. This reliance could require the company to retain additional risk on its balance sheet or secure replacement coverage at higher costs, which would directly affect profitability.
Regulatory conduct: Auditors have flagged customer redress uncertainty as an emphasis of matter, signaling potential FCA enforcement actions or compensation obligations. These could necessitate significant financial provisions. The scope and cost of any redress program remain undefined but constitute a material contingent liability.
Market cycle sensitivity: Marshmallow's 2024 profitability was supported by hard market pricing conditions that elevated premium levels across UK motor insurance. However, industry data indicates pricing normalization is likely through 2025. As market conditions stabilize, the company will need to demonstrate that its underwriting models can sustain profitable loss ratios without the benefit of elevated pricing.
