- Bayesian and predictive-analytics specialization is narrower than firms covering the full modern generative AI stack
- Smaller regional presence in the Grenoble area versus Paris- or Amsterdam-based firms with broader visibility
SDG Group

+ Enterprise-scale delivery capacity of roughly 2,000 staff across multiple European and international offices
