Testimonials
“We've used Toptal developers multiple times for multiple projects, and they've always been world-class—regardless of whether they've been from South Africa, Brazil, or the United States.”
Alex Haro
CEO @ Life360
“Toptal helped us when we had a hiring gap we needed to fill. The developer we received was excellent, with a great work ethic and fit in very well with the team. We are very happy with the service and would definitely consider using Toptal again in future should we need additional help. ”
David Gildeh
CEO @ Dataloop.io
“Working with Toptal has been a great experience. Prior to using them, I had spent quite some time interviewing other freelancers and wasn't finding what I needed. After engaging with Toptal, they matched me up with the perfect developer in a matter of days. The developer I'm working with not only delivers quality code, but he also makes suggestions on things that I hadn't thought of. It's clear to me that Amaury knows what he is doing. Highly recommended!”
George Cheng
CEO @ Bulavard, Inc.
“One of our most time consuming problems is finding qualified staff. We need to find the correct platform to advertise on, create a proper ad, filter through tons of applications, interview and test the applicants' capabilities, and finally take a risk by hiring. This was the old way of doing things. The new way: describe the job position to our Toptal account manager, interview a few qualified applicants, and hire with a risk-free trial -- much faster, a lot easier, and with incredible results.”
Catalin S. Balaci
Owner @ EvoBits Information Technology SRL
