Tensorway vs Data Science UA: 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).
Data Science UA
Data Science UA grew out of a 2016 data science conference in Kyiv and now runs recruiting, outstaffing and AI consulting, with a legal base in London. It offers two ways to buy. You can pay a recruiting fee for a permanent hire, which it says takes two to four weeks on average, or take the engineer on monthly outstaffing terms first. Its AI community, quoted at 10,000 to 30,000 people, gives it reach. Screening is done by recruiters, so plan your own technical interview.
