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 offers a no-compromise solution to businesses undergoing rapid development and scale. Every engineer we've contracted through Toptal has quickly integrated into our team and held their work to the highest standard of quality while maintaining blazing development speed.”
Greg Kimball
Co-Founder @ Nifti
“Toptal is a great resource for startups with ever changing product roadmaps and budgets. We had highly skilled and reasonably priced Toptal developers working for us within 8 business days of our first conversation with Toptal. It has been an empowering experience for our company to start working with Toptal.”
Chris Clark
CEO @ ModernStat Labs
“Working with Marcin is a joy, I can't find a better word. He is competent, professional, flexible, and extremely quick to understand what is required -- and to implement it -- even if the source code that's given to him is, shall we say, less than optimally elegant and clear. Oh and he has the same sense of humour as me. ;)”
André Fischer
CTO @ App Promotions
“In Higgle's early days, we needed best-in-class developers, at affordable rates, in a timely fashion. Toptal delivered! Higgle enjoyed working with Toptal and we appreciate their professionalism.”
Lara Aldag
CEO @ Higgle
“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
“Chris Wood is an absolutely exceptional Python developer, and the single most efficient programmer I've ever worked with. From the beginning of the project, Chris was instantly a vital member of the team. He's proactive, self-managed, knowledgeable, and efficient. I point him in a direction, and he delivers. Chris will be a part of the Crisis Cleanup team as long as I have anything to say about it.”
Aaron Titus
Project Manager @ Crisis Cleanup
“Back in July '12, FundedByMe needed to quickly scale our development team to create the equity crowdfunding leg of our operation. Working with a small budget, we couldn't spend time on vetting candidates, so we turned to Toptal. They identified a stellar developer that truly set the bar when it came to delivering product.”
Arno Smit
CTO @ FundedByMe.com
“Our Toptal contractor quickly came up to speed on our process and became an integrated part of our team. We look forward to growing together!”
Vitaly M. Golomb
CEO @ Keen Systems
“The Toptal process was very organized, personable, and professional. They get to know you and your project idea, and then quickly provide you with several of the world's best developers, who will work hard to achieve your vision. I found a great developer in only a few days and was able to turn my idea into a functional product.”
Ben Woratyla
CEO @ Book Swap
“I can't say enough about how happy and confident I am in working with Enrique. He brings an enthusiasm to his profession that is very refreshing, constantly surprising us with his depth of knowledge and his capability to not only complete the task, but to surpass our expectations. He presents us with solutions that we would not have thought about ourselves, and sees the problem better than we can explain it.”
Chad Berryman
Senior Technical Lead @ Zoomedia
“We've actually remodeled the way we do our work to take advantage of Toptal's capabilities. We develop pseudo code with some code fragments and send to our Toptal developer with a specific task set. The work is then further processed by the next group of Toptal engineers. It's been very efficient and we've seen a massive improvement in our development speed.”
William North
CTO & Co-Founder @ Swizly
“Toptal makes finding qualified engineers a breeze. We needed an experience 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!”
