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'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
“As a small company with limited resources we can't afford to make expensive mistakes. Toptal provided us with an experienced programmer who was able to hit the ground running and begin contributing immediately. It has been a great experience and one we'd repeat again in a heartbeat.”
Stuart Pocknee
Principal @ Site Specific Software Solutions
“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
“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
“One of our biggest and most time consuming problems is finding qualified staff. We need to find the correct platform to advertise on, create a proper ad, filter through tons of useless applications to try and find the small gems, interview and test the capabilities of applicants to see if they fit our profile and finally take a risk by hiring. This was the old way of doing things! The new way: describe the job position to our Toptal account manager, interview a few qualified applicants, hire with a risk-free trial! Much faster, a lot easier and with incredible end results.”
Catalin S. Balaci
Owner @ EvoBits Information Technology SRL
“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
“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
“Through Toptal, we were able to find and select a senior engineer who is both very professional and easy to work with. The quality of matching that Toptal enabled has been crucial to our success, it was at a fair price, and it came with a much appreciated, risk-reducing trial period.”
John Olsen
Director @ Bingo Solutions
“We needed a talented developer and we needed him/her very quickly. So we turned to Toptal and couldn't be happier with the results! Our Toptal freelancer has contributed extraordinary knowledge, talent, and startup experience to our team. We will continue to work with Toptal to fulfill our future talent needs.”
Lindsay Fairman
Founder & Owner @ FairTech Labs, LLC
“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 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
“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
“While looking for a high-level Python/Django developer, I found Toptal via a simple Google search, and that was a stroke of luck for our company. We needed a expert engineer who could start on our project immediately as we had a tight deadline. We were introduced to Simanas and immediately knew he was a great choice who had already been vetted... and he 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, and we are extremely happy with the results. Toptal is now the first place we look for expert-level help.”
