Testimonials
“Toptal's developers and architects have been both very professional and easy to work with. The solution they produced was fairly priced and top quality, reducing our time to launch. Thanks again, Toptal.”
Jeremy Wessels
CEO @ Kognosi
“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.
“The best talent is at Toptal for sure. It's way better and faster than any other means of getting top talent.”
Rajesh Nagarajan
Co-Founder & CTO @ maxmantra
“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
“I'm incredibly impressed with Toptal. Our developer communicates with me every day, and is a very powerful coder. He's a true professional and his work is just excellent. 5 stars for Toptal.”
Pietro Casoar
CEO @ Ronin Play Pty Ltd
“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
“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
“One of their engineers from Colombia has joined our team as a full-time developer for more than 6 months, sometimes flying to work on-site in New York City with us. He is one of the best developers I've ever worked with.”
Carter Cleveland
CEO @ Artsy
“We've been very pleased with our experience working with Toptal. Their team was incredibly helpful in finding us the perfect developer for our project. The work was stellar, the communication was excellent, and we couldn't have been happier with the overall experience. We're excited to work with Toptal for more projects in the future. ”
Ryan Walker
Director, Product Management @ Rand McNally
“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
“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
“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. ”
Jay Tring
Technical Team Lead, CSR Connect, Australia @ CSR Limited
“We used Toptal to hire a developer with extensive Amazon Web Services experience. We interviewed four candidates, one of which turned out to be a great fit for our requirements. The process was quick and effective. ”
