Gradient Labs, an AI company headquartered in London, England in the United Kingdom, has raised a fresh $13 million. The new capital is a Series A extension that doubles the company’s Series A to $26 million and brings total disclosed funding to roughly $30 million. The round was announced on June 1, 2026.

The extension was led by new investors Octopus Ventures and CommerzVentures, with follow-on backing from Redpoint Ventures and Exceptional Capital. It follows the company’s original $13 million Series A, which was led by Redpoint Ventures.

Founded by former Monzo executives, Gradient Labs builds a suite of AI agents that automate operations for fintech and financial services companies. Its agents handle customer service as well as processes such as lending, disputes, and Know Your Customer checks.

The company has reported 900 percent revenue growth over the past year and now supports more than 32 million end users across its deployments. Its technology is in use at institutions including Wise, Monzo, Zego, Stash, Current, and Rho. Gradient Labs plans to put the funding toward its US expansion along with strategy and technology improvements.
