Note: Founded in 2023 by former early leaders of Monzo’s machine learning and data science teams, Gradient Labs has built an AI-native operational platform specifically designed for highly regulated financial environments. Its core agentic software framework, including its flagship product "Otto", automates complex, multi-step customer operations workflows that have traditionally relied entirely on human administrative entry—such as lending, account disputes, fraud triage, card replacements, and Know Your Customer (KYC) compliance checks. Backed by built-in context engineering and compliance guardrails to safely manage regulatory constraints, Gradient Labs recorded a staggering 900% year-over-year revenue expansion, supporting more than 32 million combined end-users. The new £20m capital layer—which brings new funding alongside early backing from LocalGlobe, Puzzle Ventures, and Liquid 2 Ventures—will fuel the firm's ongoing software optimization pipelines and aggressively accelerate its market expansion across the United States, where it has already secured tier-one clients like Stash, Rho, and Current alongside its domestic base of Wise, Monzo, Zego, and Pockit.
