Tensorway vs Brainpool AI: 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).
Brainpool AI
Brainpool AI, which says it has operated since 2017 (directories give 2016), is a London company founded by researchers who met at University College London. It built a network of about 500 AI and ML experts from universities such as UCL, Oxford and Cambridge and sells access on a project basis alongside consultancy. More recently it has moved toward its own agent platform, Cortex. Buyers get academic depth by the project, but not dedicated full-time staff.
