Tensorway vs Preste: 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.

Preste

Preste is a European AI development company founded in 2019, with operations spanning Paris, France and Kyiv, Ukraine. The team focuses on computer vision, natural language processing, and custom machine learning algorithms, and was recognized by industry peers as a Top European AI Startup in 2024 and 2025 (per company website; independently unverifiable). Its dual-location structure combines French client-facing presence with Ukrainian engineering delivery.
