Tensorway vs micro1: overview

Tensorway

Tensorway is an AI engineering company from Alicante, Spain, founded in 2019, and the people behind its delivery process have been building software for more than twenty years. What sets its staffing service apart is who does the screening. Senior AI engineers review each candidate's code, set a practical task in the exact specialization the client asked for and check how the person communicates, so a CTO receives two or three people who have already passed a technical bar (per company website; independently unverifiable). The roles cover ML, computer vision, NLP, MLOps and RAG work. Smaller published projects include an agent that grades GAMSAT practice essays, invoice extraction for a fintech client and ball-hit detection for a fitness game (per company website; independently unverifiable).

micro1

micro1 was founded in 2022 by Ali Ansari and is based in California. Its AI recruiter, Zara, runs a structured interview of 20 to 40 minutes with every applicant. The company raised a Series A at a $500 million valuation in September 2025 and now earns most of its revenue supplying vetted experts to AI labs for model training. Engineering teams can still hire through it, but an automated interview is a different thing from a senior engineer reviewing code, and its focus has moved toward lab work.

Tensorway vs micro1: pros and cons

Tensorway
+ The technical screen is a code review plus a hands-on task in the role you are hiring for, set by working AI engineers
+ Covers the harder-to-fill roles on this list, including speech, edge computer vision and RAG specialists
+ A two-week trial sprint comes before any longer commitment, and a poor fit is replaced at no cost (per company website)
+ Code, documentation and trained models stay in your repositories, and handover to in-house staff is planned from the start
- No published rate, so budgeting needs a call
- The bench is in the low hundreds at most, so it cannot staff twenty seats in a month the way Turing or Andela can
- AI and ML roles only; a CTO who also needs front-end or mobile engineers will need a second supplier
micro1
+ Can screen a very large number of candidates fast
+ Experience with AI-lab evaluation work
+ A short trial before a longer contract
- AI interviews replace engineer judgment in the screen
- Most revenue now comes from AI labs, not product teams
- Headquarters is listed differently across sources
