Gradient Labs

Gradient Labs builds autonomous AI customer-support agents designed for regulated industries, particularly financial services, where accuracy and compliance matter. Its agent, Otto, learns a company's specific products and processes to resolve complex customer inquiries end-to-end, reportedly handling up to around 90% of queries at high quality-assurance pass rates. Founded in 2023 by Dimitri Masin, Neal Lathia and Danai Antoniou, all early employees of UK challenger bank Monzo, the London-based company deploys across institutions including Wise, Monzo, Zego, Stash, Current and Rho. After a £2.8M seed led by LocalGlobe and an initial Series A round, it raised a $26M Series A led by Octopus Ventures and CommerzVentures with participation from Redpoint Ventures and Exceptional Capital.
