ClaimSorted, the company transforming insurance claims from a chronic pain point into a competitive advantage, today announced a £10m 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 prominent insurance veterans.

The company 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. Claims are the moment of truth, the industry's shopfront, and at that moment most TPAs struggle to deliver.

ClaimSorted spent a year assembling a best-in-class 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.

Since launch, ClaimSorted has partnered with more than 20 insurers across the US, UK, and EU, 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.

Ask anyone in insurance where the weakest link is, and most will point to claims TPAs. 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. 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.

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. 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.
