Toptal vs LeewayHertz: overview

Toptal

Toptal was founded in 2010 by Taso Du Val and Breanden Beneschott as a fully remote company with no headquarters office; it is registered in the United States. It is a curated freelance marketplace, which means its engineers are independent contractors rather than employees. Its AI offering covers ML, generative AI, NLP and LLM application developers, and the company says it can match an AI engineer in about 48 hours and cites a 98% trial-to-hire rate (per company website; independently unverifiable). Third-party sources report rates from roughly $60 to over $150 an hour plus an initial deposit.

LeewayHertz

LeewayHertz was founded in 2007 and, while it historically marketed itself from San Francisco, does most of its engineering in India. The Hackett Group acquired it in September 2024 to add generative-AI solution and implementation work, including the ZBrain platform. It offers dedicated developers alongside project delivery, though its public material leads with platforms and consulting more than staffing.
