Tensorway vs KORE1: overview
Tensorway
Tensorway is an AI engineering company founded in 2019 and based in Alicante, Spain, with more than 20 years of software engineering experience in its leadership and delivery processes. Its staff-augmentation service places ML engineers, LLM engineers, AI agent developers, MLOps engineers, computer-vision and NLP specialists, data engineers and RAG specialists directly into a client's own team, where they work in the client's Slack, Jira and repositories. Candidates are screened by senior AI engineers through a code review, a practical task in their specialization and a communication check, so the client receives a shortlist of two or three people that is already technically vetted. Tensorway handles contracts and admin; the first engineer typically starts within one to two weeks and a full squad within three to four weeks (per company website; independently unverifiable). One published case study describes a U.S. law practice, Liner Legal, cutting medical-record processing from about a week to 5–15 minutes (per company website; independently unverifiable).
KORE1
KORE1 was founded in 2005 and is headquartered in Irvine, California, serving clients in more than 30 U.S. metro areas. Unlike most companies on this list, it is a traditional staffing and recruiting firm: it places AI and ML engineers as contractors, contract-to-hire or direct employees of the client. It says it fills AI roles in an average of 17 days with 92% twelve-month retention (per company website; independently unverifiable).
