London’s ClaimSorted raises €11.4 million in one of the largest InsurTech Seed rounds this year

ClaimSorted, a British startup transforming insurance claims from a “chronic pain point into a competitive advantage“, today announced a €11.4 million Seed funding round, one of the largest InsurTech Seed rounds on record.

The round was led by Atomico, with participation from Eurazeo, Y Combinator, firstminute capital, Start Ventures Capital, and a network of insurance veterans.

“Ask anyone in insurance where the weakest link is, and most will point to claims TPAs,” said Pavel Gertsberg, Founder and CEO of ClaimSorted. “We saw the claims process being painfully slow. Mistakes made by TPAs that should’ve been caught early ended up eating our entire profit margin. So, we decided to build something better.”

ClaimSorted’s Seed round positions it among the largest early-stage InsurTech fundraises in Europe in 2025, particularly within the claims and operations automation segment.

Most comparable startups have raised smaller rounds – for example, muffintech (€3.5 million), Loxa (€1.9 million), and Klaimy (€1.2 million), each focusing on specific insurance automation niches. Larger rounds, such as Baobab Insurance’s €12 million Series A, tend to come from companies expanding underwriting or cyber-risk offerings rather than claims operations.

The most directly comparable model is MarvelX’s €5.4 million round, which funds development of an AI backbone for insurance workflows, including claims.

In this context, ClaimSorted’s round underscores the growing investor focus on AI-enabled claims modernisation, an area where Europe is seeing increasing activity but relatively few players at scale.

“Insurers don’t want yet another ‘AI claims platform’ with an ambiguous value proposition. They want a tangible end-to-end service that takes the headache out of claims, supports their customers when they need it most, and protects their bottom line,” said Andreas Helbig, Partner at Atomico “And it’s working: Through faster and better claims resolution, ClaimSorted is increasing policyholder NPS by +10, while delivering significant reduction in cost per claim. It’s rare that we see such a clear and strong ROI.”

Founded in 2024, ClaimSorted was born out of firsthand frustration. While running their own insurance business, Founders Pavel Gertsberg and German Mikulski relied on outsourced claims providers, also known as, third-party administrators (TPAs) to process claims.

But they kept running into the same issues insurers face across the board: claims that should take a week dragged on for months, inconsistent service hurt customer retention and poor claims management by TPAs eroded profitability.

They also quickly realised that customers don’t care about underwriting or glossy ads, they care about what happens when life goes wrong: the car breaks down, they lose their job or there’s a fire.

“By combining a market leading claims team with a suite of embedded AI agents, we’re able to provide policyholders with a 5-star experience during the claims process, settle claims 3 times faster than traditional TPAs while helping insurance companies save millions,” continued Gertsberg.

ClaimSorted spent a year assembling their team with experience from top insurers including Hiscox, Lemonade, AXA, Hartford, and Liberty Mutual. That team was merged with the startup’s proprietary AI-enabled claims platform, resulting in a next-generation TPA: Claims TPA 2.0.

“Claims aren’t just a cost centre, they’re the moment of truth in the insurance journey,” added Gertsberg. “With this funding, we’re doubling down on helping insurers turn claims into their biggest asset.”

Since launch, ClaimSorted has partnered with more than 20 insurers across the US, UK, and EU, reportedly serving tens of thousands of policyholders.

This new funding will accelerate product development, expand operations across key global markets, and scale partnerships with insurers seeking a modern alternative to legacy TPAs.
