Gradient Labs is a London-based AI company founded in 2023 by Dimitri Masin, Neal Lathia, and Danai Antoniou, three early employees of UK challenger bank Monzo. The company builds AI agents that automate complex customer operations specifically for regulated industries such as financial services, where errors carry compliance and financial consequences.
The company's flagship agent, Otto, is described as a procedural AI agent that learns a company's specific products, policies, and processes. Rather than relying on generic language-model responses, Otto follows defined procedures so it can handle complex, high-stakes inquiries reliably and safely. The agent targets the difficult back-office work that generic chatbots cannot handle: customer support, fraud handling, lending, and dispute resolution.
Gradient Labs reports strong performance metrics, stating that Otto resolves up to 90% of queries with a 98% quality-assurance pass rate while reducing operating costs by roughly 75%. The founders' background at a regulated bank informs the product's emphasis on auditability and safe automation in environments where accuracy is non-negotiable.
The company raised a $13 million Series A in July 2025, reported as over €11 million, led by Redpoint Ventures with participation from Exceptional Capital, Liquid 2 Ventures, LocalGlobe, and Puzzle Ventures. The raise was reportedly closed in roughly a week, reflecting strong investor interest.
Gradient Labs demonstrated early traction by signing nine customers within three months of launch, including one of Europe's largest banks. It competes with AI customer-support players like Decagon, Lorikeet, and Sierra, but differentiates with a regulated-industry focus and a procedural agent architecture designed for compliance-heavy financial workflows.
