Cnbc 02e66b
"Tech companies simply cannot find the quality employees they want to hire. The solution: Toptal."

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
“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
“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
“Working with Toptal has been a great experience. Prior to using them, I had spent quite some time interviewing other freelancers and wasn't finding what I needed. After engaging with Toptal, they matched me up with the perfect developer in a matter of days. The developer I'm working with not only delivers quality code, but he also makes suggestions on things that I hadn't thought of. It's clear to me that Amaury knows what he is doing. Highly recommended!”
George Cheng
CEO @ Bulavard, Inc.
“Toptal was the best thing to happen to my web app. Initially, I hired a team of freelancers from India through another freelancing website—which was a nightmare. In fact, it was so bad that I had to start again from scratch, which is when I found Toptal. The experiences were like night and day. It was so refreshing to get partnered up with a quality developer that I could trust due to Toptal's extensive screening process. I will only use Toptal from now on and highly recommend you do the same.”
Chris Holtzhauer
CEO @ HootRecruit
“Always incredibly responsive, prompt, and flexible, Anna has done an outstanding job -- her work is exactly what we needed. Toptal has been a great experience for us due to the ease of getting a project going with quality talent at a cost that fits our budget. The automated online system for managing everything during onboarding was also impressive.”
Cody Wilke
Product Manager @ Crucial Life Sciences Data Solutions
“We have been incredibly happy with our Toptal experience. Initially a skeptic, the process to find and recruit a fabulous iOS developer was very easy. Rather than sifting through hundreds of CVs, we saw two and hired them. They have worked effectively, getting up to speed incredibly quickly and have almost become part of the team. We would definitely use Toptal again. ”
James O'Day
Co-Founder @ Pearlshare
“In our 2 years of operations this is by far the most enjoyable and productive working relationship we have had with a developer. I plan on continuing to recommend Toptal's services to other entrepreneurs I run into.”
David Sawyer

Abner Guzmán Rivera
CTO and Chief Scientist @ Photo Kharma
“Our experience with Toptal was very good. We had an open ended development project when we got started and the programmer from Toptal was very helpful, working with us on everything from the top level outline all the way down to development and delivery of functioning code." ”
Michael Milton
VP of Engineering @ SLANTRANGE
“Getting set up with Toptal and finding a new team member was so easy, I don't know why anyone wouldn't give it a try. Best of all, we no longer have to worry about finding great people to help with our projects!”
Mike Branch
President & CTO @ Harbor System Integrators, Inc
“To take advantage of Toptal's capabilities, we actually remodeled the way we do our work. We develop pseudo code with some code fragments that we send to our Toptal developer, who has 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
“I couldn’t have been more pleased with Toptal. They are professional, quick, well priced, and fun. I will be using them again for my next project, and the next, and the next, and the next ... ”
Mac Smith
President @ New Texas Investments
“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 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
“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
“Tripcents wouldn't exist without Toptal. Toptal Projects enabled us to rapidly develop our foundation with a product manager, lead developer, and senior designer. In just over 60 days we went from concept to Alpha. The speed, knowledge, expertise, and flexibility is second to none. The Toptal team were as part of tripcents as any in-house team member of tripcents. They contributed and took ownership of the development just like everyone else. We will continue to use Toptal. As a start up, they are our secret weapon.”
Brantley Pace
CEO & Co-Founder @ Tripcents

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
