Tensorway vs ML6: overview

Tensorway

Tensorway is a Spain-headquartered machine learning and AI development company spun out of its parent software engineering firm. The team of roughly 50 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 its parent'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.

+ Backed by parent company's 25-year engineering track record and hiring pipeline
+ Established project-management and QA processes for predictable, well-documented delivery
+ Broad service range from LLM integration to computer vision to predictive analytics
+ Flexible engagement models including fixed-price PoC for budget-constrained startups
+ Based in the EU (Spain), simplifying GDPR-compliant data handling for European clients
- Young standalone brand (founded 2019) with a shorter independent track record than its 25-year-old parent company
- Public case studies are limited in number relative to larger regional players
- Smaller team size (around 50) means less capacity for very large enterprise programmes
ML6
+ One of Europe's longest-running pure-play ML engineering firms, founded in 2013
+ Official OpenAI Services Partner and Google Cloud partner
+ Deep MLOps and production infrastructure expertise, not just model prototyping
+ 150-person specialist team with dedicated practice areas across computer vision, NLP, and MLOps
- Higher minimum engagement size than boutique competitors, less suited to small startups
- Primarily Benelux-based delivery, fewer nearshore options for very tight budgets
