Tensorway vs Keyrus: pros and cons

Tensorway
+ Boutique team structure — clients work directly with senior deep learning engineers, not account managers
+ Hands-on production ML delivery on AWS across computer vision and NLP workloads
+ Deep specialisation in deep learning, NLP, computer vision, and agentic AI rather than broad ML generalism
+ Established project-management and QA processes for predictable, well-documented delivery
+ Strong delivery track record in deep learning and NLP, with client references available under NDA
- Smaller specialist team (50+) — less suited to very large enterprise programmes needing broad staffing
- AWS-centric delivery — teams standardized on other clouds may need added integration effort
Keyrus
+ Global footprint: 20+ countries, 3,500+ professionals
+ Industrial-AI focus — moves clients from PoC to production scale
+ Strong analytics and BI alongside ML for full data stack coverage
+ AI testing and validation capability
- Large-firm pricing not suited to startup or SMB budgets
- AI is one offering within broader data consulting — not ML-first
