Gradient Labs, a London company that builds AI agents for customer operations in financial services, raised $13m on 1 June 2026. The money extends its Series A, which now stands at $26m.
Octopus Ventures and CommerzVentures, both new investors, led the extension. Redpoint Ventures, which led the first part of the Series A, and Exceptional Capital took part again. Tech.eu reported that total funding is now around $30m. No valuation was disclosed.
Chief executive Dimitri Masin said investors approached the company wanting to back it before its next full round. The funds are earmarked for expansion in the United States, strategy and technology work, according to Tech.eu. The company says it will also build an operating system that ties its agents together and meets regulatory scrutiny.

What Gradient Labs does
Gradient Labs sells AI agents that take over work normally done by customer-operations teams at banks and fintechs. Its product list on the company's announcement covers a lending agent that handles the borrower lifecycle from a missed payment through collections to an agreed repayment plan, a disputes agent that handles intake, investigation and chargebacks, and a know-your-business agent that runs identity and document checks. It also offers voice AI, which the company says is in production at scale.
The company says its agents share context and memory and can work next to a customer's existing AI tools. It cites guardrails for the UK Financial Conduct Authority's Consumer Duty and the EU AI Act, and offers a money-back guarantee if a deployment does not deliver what was scoped.
Masin, who was an early employee at Monzo, founded the company in 2023 with Neal Lathia and Danai Antoniou, whom he also met there. The company did not give a headcount, but says it is hiring.
Traction the company reports
In its own announcement, Gradient Labs said revenue grew 900% over the past year and that its agents serve more than 32 million end users. Those figures come from the company and were not independently verified. It named Wise, Zego, Monzo, Pockit, Current, Stash and Rho among its customers, and said customer satisfaction was higher than for human teams in every deployment, with some scores up to 98%.
Tech.eu said the company works with fintechs in the US and Europe and handles hundreds of thousands of customer calls a month across its lending deployments alone.
Who invested
The extension was led by Octopus Ventures and CommerzVentures. Redpoint Ventures and Exceptional Capital, existing backers, followed on. The first $13m of the Series A was led by Redpoint in 2025, according to Tech.eu.
The company's blog post presents the raise as the foundation for what it calls autonomous banking. Masin wrote that banks should run on autopilot and that the technology to do it already exists.
The funding so far
With the extension, the Series A totals $26m. Tech.eu put the company's total funding at around $30m, which would imply earlier capital beyond the two Series A tranches, though the sources do not itemise it.
The raise comes as banks and fintechs test AI agents for regulated work such as lending and disputes, where errors carry compliance risk. Gradient Labs is betting that a single system able to meet those rules will win larger deployments in the US as well as in Europe.
