What is 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.

Toptal works primarily with clients in Technology, Finance, Healthcare, Media, Retail sectors. Its primary differentiator is: Hourly or weekly booking of screened freelancers with a no-risk trial.
