ML6 vs Gradient Labs: overview
ML6
ML6 is an AI engineering company founded in 2013 by Nicolas Deruytter and Michael Lemmer, headquartered in Ghent, Belgium, with roughly 178 employees across offices exclusively in Ghent, Amsterdam, Berlin, and Munich. Unlike most firms on this list, it operates with zero non-EU offices — every delivery location is inside the EU, which materially simplifies data-residency and cross-border transfer questions for European procurement teams. Its positioning as "Enterprise Superintelligence" reflects a broader AI engineering practice, of which agentic AI is one growing part.
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.
