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
“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've used Toptal developers multiple times for multiple projects, and they've always been world-class—regardless of whether they've been from South Africa, Brazil, or the United States.”
Alex Haro
CEO @ Life360
“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
“My experience with Toptal has exceeded expectations. I needed to quickly find a front-end developer, and the first person they recommended was a perfect fit. A month later, I needed an iOS developer and they delivered again. I'm incredibly impressed with the quality of the people in Toptal's network and how quickly I was able to find a match for my needs.”
Bruno De Martino
Head of Product @ Token
“My business relationship with Toptal has been nothing short of terrific. From reviewing my project with their team to choosing a highly-talented developer, and all the way through releasing our application, it has been an incredibly smooth and successful experience.”
Gary Craig
Senior Analyst @ NetApp
“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
“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
“We've had multiple needs for various development talent and Toptal doesn't disappoint. They truly focus on matching the best developer to our specific engagements, and they continue to stay connected in an effort to exceed our expectations at all times”
Mindle Hastings
Sr. Product Manager @ Bodybuilding.com
“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
“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
“Toptal understood our project needs immediately. We were matched with an exceptional freelancer from Argentina who, from Day 1, immersed himself in our industry, blended seamlessly with our team, understood our vision, and produced top-notch results. Toptal makes connecting with superior developers and programmers very easy.”
Jason Kulik
Co-Founder @ ProHatch
“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
“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
“Robert was such a breath of fresh air. He was an excellent communicator and knew exactly what I was looking for. Now, I have a website that works better than I thought it could for less than the cost -- and in half the time -- it would have taken other developers. Robert is as good as they come, a true professional -- anyone thinking of working with him, hire him. You won’t regret it.”
Matthew Bennett
CEO @ Winning Social LLC
“The best talent is at Toptal for sure. It's way better and faster than any other means of getting top talent.”

Michael Gluckman
Data Manager @ Mxit
“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
“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.
“We needed some short-term work in Scala, and Toptal found us a great developer within 24 hours. This simply would not have been possible via any other platform.”
Franco Arda
Co-Founder @ WhatAdsWork.com
“I really enjoyed my experience with Toptal. Searching for a developer was both painless and engaging, and the first match was a perfect fit! Toptal is a fantastic way to find talented developers for small or large aspects of your project.”
Willem Shepherd
Creative Director @ Mookieyams
“Toptal’s ability to rapidly match our project with the best developers was just superb. The developers have become part of our team, and I’m amazed at the level of professional commitment each of them has demonstrated.
