Tensorway vs Emerline: overview

Tensorway

Tensorway traces back to 2019 as the AI-agent spin-out of a much older Alicante, Spain software house, but the team itself is deliberately sized like an agency — 50 to 249 people — rather than scaled into a global systems integrator. A six-phase delivery methodology carries a client from assessment to a working agentic MVP in about a month, compliance included as a named phase rather than an afterthought, and a discovery-first track lets smaller buyers test the fit before signing a full engagement. Pairing agency-scale headcount with a decades-old parent company is an unusual combination among the options on this list.

Emerline

Emerline is an IT services and consulting agency founded in 2011, with LinkedIn listing its headquarters in Miami, Florida (other sources cite Mountain View, California), and roughly 500–520 employees across Europe, North America, and Asia. It has operated as part of LeverX Group since 2011, helping startups and established businesses build software products, with agentic AI as a newer addition to that practice — the LeverX Group ownership structure is a material fact buyers should confirm during due diligence.
