Testimonials
“In Higgle's early days, we needed the best-in-class developers, at affordable rates, in a timely fashion. Toptal delivered! ”
Lara Aldag
CEO @ Higgle
“Getting set up with Toptal and finding a new team member was so easy, I don't know why anyone wouldn't give it a try. Best of all, we no longer have to worry about finding great people to help with our projects!”
Mike Branch
President & CTO @ Harbor System Integrators, Inc
“Toptal has helped my business tremendously by finding, vetting, and recruiting the talent I need, at the right time. I’d definitely recommend it to others.”
Xavier Xicay
CEO & Creative Director @ Tuatara Corp
“Toptal developers deliver. Hiring my first developer on Toptal was such a pleasant experience that I quickly turned around and hired another. Every developer I've hired on Toptal has been professional, skilled, and self-managing—a pleasant departure from the typical freelancer marketplace.”
Mike Riess
Owner @ RiessGroup
“I’m a big believer in the saying, ‘hire smart, or manage tough’. For us non-hackers, Toptal takes the guesswork out of hiring. Their coders are vetted, and the work is guaranteed. Why look anywhere else?”
Greg Archbald
Founder & CEO @ Greasebook
“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.
“We needed a programmer to help push a project over the finish line, and I figured -- best case -- Toptal would find someone who would come in and complete a few tickets. Instead, Sergio blended right in with the team and made significant progress after mere days of ramp-up. He even offered to take his laptop with him on vacation in case we had a customer issue with his code! He surpassed my expectations, and then some.”
Bryan Adams
CTO @ Healthsense
“When you're growing quickly and your internal resources are strapped, you need to find a way to move forward regardless. We couldn't have done it without Toptal. From content creation to programming and design, we were able to leverage the expertise of Toptal's network to move even faster that we could have otherwise. They prioritized finding us the right person, not just a person. Every single one they introduced us to was not only qualified and professional, but also eager to help us.”
Josh Leskar
Manager @ Udemy
