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
“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
“We really enjoy working with Toptal. The experience has been very positive, and we'd recommend it to anyone seeking developers on-demand.”
Jeff Kerr
CEO @ CaseFleet
“Toptal makes finding qualified engineers a breeze. We needed an experienced ASP.NET MVC architect to guide the development of our start-up app, and Toptal had three great candidates for us in less than a week. After making our selection, the engineer was online immediately and hit the ground running. It was so much faster and easier than having to discover and vet candidates ourselves.”
Jeff Kelly
Co-Founder @ Concerted Solutions
“We had a wonderful experience with our Toptal consultant. He was very reliable and punctual, delivering excellent work on a budget—we will certainly be using him again!”
Barbara Karpf
President @ DecoratorsBest
“Dave as a developer was absolutely fantastic! The guidance that he provided us will allow us to make tremendous improvements to the next version of our application.”
Baroni Parson
IT Manager @ City Real Estate Advisors, Inc.
“I needed help, and fast. I did not want to hire a random coder I met online- I was worried about security, and many other issues. Toptal was there when I needed them- and has been fantastic to work with. Outsourcing is full of terrible stories- Toptal is the story that is the giant exception. I give them my highest recommendation.”
Michael Feder
Founder & CEO @ PrayerSpark
“As an internet marketing company specializing in pay-per-click management, our clients frequently ask us to provide services that fall outside the scope of our primary business. We have found Toptal to be exactly the resource we need to connect with contractors so we can deliver our clients top tier web development talent at a reasonable cost.”
Pashmina Lalchandani
Owner @ Flowsimple
“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 really enjoyed my experience with Toptal. Searching for a developer was both painless and engaging, and the first match was a perfect fit! Toptal is a fantastic way to find talented developers for small or large aspects of your project.”
Willem Shepherd
Creative Director @ Mookieyams
“We recently launched our app with the help of Toptal and Nikola, an iOS developer. I was immediately impressed with the constant communication, detail, and level of talent that Nikola brought to the table. More importantly, when the project was underway, Nikola proactively provided creative workarounds for unforeseen hurdles and challenges. I couldn't be happier with our engagement and would highly recommend Nikola and Toptal.”
Chip O'Toole
Founder @ Humans Helping Robots LLC
“We had a great experience with Toptal. They paired us with the perfect developer for our application and made the process very easy. It was also easy to extend beyond the initial time frame, and we were able to keep the same contractor throughout our project. We definitely recommend Toptal for finding high quality talent quickly and seamlessly.”
Ryan Morrissey
CTO @ Applied Business Technologies, LLC
“We have been with Toptal for over two years and have hired through them multiple times. They've never failed to deliver with world-class talent and customer service and have been our first choice when scaling our team.”
Stuart Reavley
Product Lead @ ClassDojo
“We needed a expert engineer who could start on our project immediately. Simanas exceeded our expectations with his work. Not having to interview and chase down an expert developer was an excellent time-saver and made everyone feel more comfortable with our choice to switch platforms to utilize a more robust language. Toptal made the process easy and convenient. Toptal is now the first place we look for expert-level help.”
Derek Minor
Senior VP of Web Development @ Networld Media Group
“With the pressure on and millions watching the Cleveland Cavaliers during the NBA Playoffs, Toptal delivered the talent and expertise needed to launch a brand new fan engagement platform.”
