Tensorway vs BairesDev: 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).
BairesDev
BairesDev was founded in Buenos Aires in 2009, is headquartered in San Francisco and employs several thousand engineers across Latin America. Buyers can choose staff augmentation, dedicated teams or project delivery, and the AI practice covers ML, data engineering and generative AI. It is a practical choice when one contract needs to cover AI engineers and the software developers around them. As a generalist, though, its AI depth varies by engineer, and rates are not published.
