The story behind Gradient Labs
Dimitri, Neal, and Danai met at Monzo–the UK’s most popular neobank–where they started and scaled the Data Science and Machine Learning disciplines.
In the earliest days of the bank, its lower volumes of customer support meant that agents could deliver an unimaginably personal experience to each customer: a level of service that is truly challenging to scale as a company grows. Dimitri, Neal, and Danai spent years working on automation projects across customer operations and financial crime systems, at the intersection of AI, product, and regulatory compliance.
Gradient Labs was born after the launch of GPT-4. Weekends spent hacking with new LLMs showed that it was now possible to entirely automate most of the manual, repetitive work in the financial services–delivering safe, compliant, and exceptional customer experiences.
The initial team spent 14 months developing in stealth, focusing on quality to build something financial institutions could trust to handle support autonomously. When Gradient Labs finally launched their flagship AI agent in 2024, it outperformed even the best human on support teams and earned customer satisfaction scores of up to 98%.
Gradient Labs has grown to over 20 employees and secured a Series A round in 2025, continuing to drive its vision of delivering exceptional customer service at scale across regulated industries.
