Testimonials
“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
“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
“What attracted us to Toptal was that Toptal is sourcing its talent from a global pool. The selection process is very stringent. They’re sourcing the talent not only based on capabilities -- sourcing the best 3% -- but also based on cultural fit, which is really important to us. We had an amazing experience working with Toptal. Toptal helped us achieve our goals by bringing us very high-quality resources, on very short notice.”
Elmar Platzer
Digital Transformation Leader, CSR Australia @ CSR Limited
“I am more than pleased with our experience with Toptal. The professional I got to work with was on the phone with me within a couple of hours. I knew after discussing my project with him that he was the candidate I wanted. I hired him immediately and he wasted no time in getting to my project, even going the extra mile by adding some great design elements that enhanced our overall look. ”
Paul Fenley
Director @ K Dunn & Associates
“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
“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.
“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
“Finding a good developer who specialised in the technologies we use seemed like an impossible task... until we used Toptal. We had several trial periods and have just accepted our first developer to join the team! The whole process went seamlessly and without any surprises or hidden costs. We are very happy and will continue to work together!”
Artem Tolmachev
CEO @ eKids.nl
“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 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
“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
“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
“Toptal is amazing. Sourcing and interviewing candidates has always been incredibly cumbersome and difficult - and usually takes weeks or months to find the right people. With Toptal, we had 5 candidates in 2 days that were all perfect for the job. They made the scheduling of interviews easy and straightforward and we were working with a top-level developer within 2 weeks. I love you, Toptal.”
Ian Fosbery
CTO @ NMRKT
“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
