"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
Fox 7ef901
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
“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
“Robert was such a breath of fresh air! I’m used to working with developers who don’t speak good English, don’t understand my needs, and are bad communicators in general. But Robert was not only an EXCELLENT communicator, he knew exactly what I was looking for and made it better than I thought possible. Now I have a website that works better than I thought it could for less than the cost it would have taken other developers, and in half the time. Robert is as good as they come, and a true professional. Anyone thinking of working with him, stop thinking about it and hire him. You won’t regret it.”
Matthew Bennett
CEO @ Winning Social
“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
“Working with Enrique has been a pleasure and a relief. His knowledge in the IT space is broad and in-depth. Zoomedia has been in need of this level of support for some time and I feel confident we are an exponentially stronger team with Enrique on board.”
Justin Bane
Senior Technical Lead @ Zoomedia
“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
“As a growing startup, finding top-notch engineering talent at affordable rates is one of the biggest challenges. After being frustrated with unreliable local contractors in New York, we turned to Toptal. We worked closely with Michal in Poland for 5 months and were thrilled with the results. Michal was an outstanding engineer who communicated flawlessly and took control of our project in ways that far exceeded my expectations. I give Michal and Toptal my highest endorsement and will continue to use and recommend them to anyone looking for software engineering talent.”
David Baker
Founder @ Spins.FM
“I struggled for weeks with a Youtube API-specific problem and couldn't find anyone to solve it. Toptal immediately identified the right consultant who took the time to investigate the issue and resolve it quickly. The process was seamless and I will continue to use Toptal with any other issues that arise.”
Rohit Gupta
CEO @ Bollyshake
“We used Toptal to hire a developer with extensive Amazon Web Services experience. The process was quick and effective. We interviewed four candidates one of which turned out to be a great fit for our requirements. We plan to use Toptal again in the future and would recommend their services.”
Abner Guzmán Rivera
CTO and Chief Scientist @ PhotoKarma, Inc.
“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
“I've gotten 1 developer from Toptal so far. He's a really good part of our team. I'm planning on adding another from Toptal in the near future. Toptal is a big help these days when recruiting is a big part of my job.”
Aaron Rubin
Founder & CEO @ ShipHero
“Best talent is here for sure. Toptal hiring and overall working experience has been wonderful. This is way better and faster than any other means of getting top talent.”
Rajesh Nagarajan
Co-Founder & CTO @ maxMantra
“Andrea is doing an amazing job. I don't think we could have gotten a better person. He is fun to work with, he thinks out of the box, and he is extremely knowledgeable in what he is going. He not only does an excellent job, he also helps our company to differentiate our business model further (e.g. making our app offline-capable). I would recommend Andrea as well as Toptal any time to any friend.”
Pascal Girardat
Co-Founder / CEO @ Lifestage Solutions AG
“We needed some short-term work in Scala, and Toptal found us a great developer within 24 hours. It was done quickly for a specific need, and it's been great. It simply would not have been possible via any other platform.”
