Toptal on TV
"Toptal is killing it, it kind of owns this market."
Andrew Ross Sorkin Reviews Toptal
Cnbc 02e66b
"Tech companies simply cannot find the quality employees they want to hire. The solution: Toptal."
Liz Claman´s Review of Toptal

Toptal in the press
“Despite accelerating demand for coders, Toptal prides itself on almost Ivy League-level vetting.”
Selina Wang
“Toptal allows corporations to quickly assemble teams that have the right skills for specific projects.”
Steven Norton
Testimonials
“My business relationship with Toptal has been nothing short of terrific. From reviewing my project with their team to choosing a highly-talented developer, and all the way through releasing our application, it has been an incredibly smooth and successful experience.”
Gary Craig
Senior Analyst @ NetApp
“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.
“Our experience with Toptal was very good. We had an open ended development project when we got started and the programmer from Toptal was very helpful, working with us on everything from the top level outline all the way down to development and delivery of functioning code." ”
Michael Milton
VP of Engineering @ SLANTRANGE
“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
“I couldn’t have been more pleased with Toptal. They are professional, quick, well priced, and fun. I will be using them again for my next project, and the next, and the next, and the next ... ”
Mac Smith
President @ New Texas Investments
“We're a small firm with big dreams. After trying 4 or 5 local or outsourced developers, we were out of options. I'd heard of Toptal, but was worried that my company wasn't big enough for them. After calling them up, I found out that I didn't need to meet any minimum budget and was immediately put in touch with a developer to talk through my problems and goals. A day later, he got back to me with a list of possible solutions. After 9 months and 5 developers, Toptal got me my solution in a single week at a price I could afford.”
Kevin Ramirez
Co-Founder @ SixtyVocab.com
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin
Chief Technologist and Co-Founder @ PriceBlink
“I've been very happy with Juraj. He is efficient, writes great code, and is an extremely nice guy to work with. Most importantly, he is self-motivated -- in his initial pass at the code base he has contributed several optimizations and stability improvements.”
Matt Cotton
Dev Team Lead @ eFolder
“The developers I was paired with were incredible -- smart, driven, and responsive. It used to be hard to find quality engineers and consultants. Now it isn't.”
Ryan Rockefeller
CEO @ Radeeus
“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
“John has been so great to work with! He has met all our requirements, done a speedy job with excellence, and has completed everything we’ve asked him to. Working with him has been a great experience.”
Jenny Lord
Communications Project Manager @ Lake Pointe Church
“Toptal has provided us developers for a wide range of projects. They are quick to provide candidates, and always very quick in communication. We have been happy with the quality of work from the developers as well as the Toptal representatives. Highly recommend!”
Gena Romano
Vice President of Digital @ VOX Global
“Toptal helped us achieve our goals by really understanding what we were looking for. They worked with us very closely to figure out what the right talent looked like -- from a technical, cultural perspective -- and helped us get the onboarding done quickly so the talent could be effective as soon as possible. ”
