Toptal vs Data Science UA: 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.
Data Science UA
Data Science UA grew out of a 2016 data science conference in Kyiv and now runs recruiting, outstaffing and AI consulting, with a legal base in London. It offers two ways to buy. You can pay a recruiting fee for a permanent hire, which it says takes two to four weeks on average, or take the engineer on monthly outstaffing terms first. Its AI community, quoted at 10,000 to 30,000 people, gives it reach. Screening is done by recruiters, so plan your own technical interview.
