Tensorway vs BJSS: 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.
