Tensorway vs Probayes: 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.
Probayes
Probayes, based in Montbonnot-Saint-Martin near Grenoble, France, is a private AI and data science company founded in 2003. With around 86 employees, Probayes specializes in Bayesian modeling, predictive analysis, and optimization for the automotive, defense, finance, and health sectors, making it one of the longest continuously operating AI-focused firms in this list.
