Toptal vs micro1: overview
Toptal
Toptal, founded in 2010 and run as a remote-first company, is a freelance marketplace rather than an employer, and its AI pool covers machine learning, generative AI, NLP and LLM work. Its screening is the most documented of any network here. The FAQ describes a process of three to eight weeks: an English and communication check, algorithm and computer science tests, several technical interviews with senior engineers, and a test project. Toptal says fewer than 3% of applicants get through. New engagements start with a no-risk trial period. The trade-off is price and continuity, because freelancers set their own rates and can leave for another client.
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.
