Tensorway vs Pento: overview

Tensorway

Tensorway, based in Alicante, Spain since 2019, sells AI engineers in three shapes, and that flexibility is why it tops this list. A full-time dedicated engineer is billed at a monthly rate. A part-time fractional expert is billed by the hour or the week. Either way, the work starts with a two-week trial sprint, and the commitment is monthly, so a team can grow or shrink between sprints (per company website; independently unverifiable). Its engineering habits come from a lineage of more than 20 years in software. Squads usually begin with two to five LLM, agent or data engineers, and Tensorway handles contracts and admin. In one published case, U.S. law practice Liner Legal cut medical-record review from about a week to 5–15 minutes (per company website; independently unverifiable).

Pento

Pento is a Montevideo company with 10 to 49 people that designs, builds and deploys machine learning systems for mid-market and enterprise clients. Clutch shows an hourly band of $50 to $99 and a $25,000 minimum project, so you can budget before the first call. It describes its work as either augmenting internal teams or delivering whole systems. Uruguay's working day overlaps closely with U.S. Eastern time. The small team means one or two engineers at a time.
