Tensorway vs ML6: overview

Tensorway

Tensorway is a Spain-headquartered machine learning and AI development company spun out of Anadea, a 25-year-old software engineering firm. The team of roughly 30 dedicated data scientists, AI engineers, and MLOps specialists delivers custom ML models, computer vision, NLP, and generative AI systems for clients across Europe and the US. Tensorway inherits Anadea's delivery infrastructure and hiring pipeline, giving it more engineering depth than most boutiques its size (15+ delivered ML projects per company website; independently unverifiable). As a relatively young standalone brand founded in 2019, its own market track record is shorter than its parent company's.

ML6

ML6 is a Ghent, Belgium-headquartered AI engineering company founded in 2013 by Michael Lemmer and Nicolas Deruytter. With roughly 150 AI and ML specialists, ML6 is one of Europe's most established pure-play ML consultancies, known for MLOps, computer vision, and enterprise AI infrastructure work. The company was named an OpenAI Services Partner and is a Google Cloud partner, reflecting deep hands-on delivery experience across major model providers.
