Tensorway vs Opinov8: 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.

Opinov8

Opinov8 Digital and Engineering Solutions is a London, UK-headquartered firm founded in 2017, with 200 to 300 professionals across Europe, the Americas, and MENA. Opinov8 blends software engineering, cloud, data, and AI expertise, positioning AI as a foundation of its delivery process rather than an add-on feature. The company was honored as Best AI Company in Europe by The Netty Awards, per company website; independently unverifiable.
