Toptal vs micro1: overview

Toptal

Toptal has run its remote freelance network since 2010, and its buying model is the most flexible on the hours side. You can book a machine learning, NLP or generative AI specialist for a few hours a week or full-time, billed hourly or weekly, and each new engagement starts with a no-risk trial. Toptal says fewer than 3% of applicants pass a screen that ends with interviews by senior engineers and a test project. What you give up is a stable employee: freelancers choose their clients, and Toptal publishes no rate card.

micro1

micro1 was founded in 2022 and is based in California. Its AI recruiter, Zara, interviews every applicant for 20 to 40 minutes, which lets it screen in high volume. Buyers can take contractors hourly or monthly and start with a one-week test. It raised a Series A at a $500 million valuation in September 2025, and most of its business now supplies experts to AI labs. Product teams can still buy engineers, but an automated interview is not an engineer's review.
