Gradient Labs vs Nagarro: overview

Gradient Labs

Gradient Labs is a London-based startup founded in 2023 by former Monzo Bank employees Dimitri Masin, Neal Lathia, and Danai Antoniou, with roughly 46 employees and $13M+ in Series A funding at a $60M valuation. Its flagship product, Otto, is an autonomous agent purpose-built for customer operations in regulated financial services, engineered to resolve complex queries end-to-end while maintaining compliance, reportedly achieving up to a 90% resolution rate with a 98% QA pass rate. Its narrow, financial-services-specific focus and UK domicile make it a fit for buyers wanting deep regulatory fluency over broad horizontal agent capability.

Nagarro

Nagarro SE is headquartered in Munich, Germany, founded in 1996, and publicly listed with reported headcount ranging from roughly 18,500 to 22,600 employees depending on the source and date. It has an agentic AI governance layer added to its offering, formalized through a July 2026 partnership with DigitalAPI, giving it a named third-party integration specifically for agent governance. As a German SE (Societas Europaea) with public-company disclosure requirements, it offers procurement teams a European legal entity with financial transparency comparable to the larger French systems integrators on this list.
