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
“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
“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
“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 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
“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
“We had a wonderful experience with our Toptal consultant. He was very reliable and punctual, delivering excellent work on a budget—we will certainly be using him again!”
Barbara Karpf
President @ DecoratorsBest
“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
“As a Toptal qualified front-end developer, I also run my own consulting practice. When clients come to me for help filling key roles on their team, Toptal is the only place I feel comfortable recommending. Toptal's entire candidate pool is the best of the best. Toptal is the best value for money I've found in nearly half a decade of professional online work.”
Ethan Brooks
CTO @ Langlotz Patent & Trademark Works, Inc.
“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
“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 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
“I'm incredibly impressed with the caliber of the Toptal developers I have worked with - they have proven themselves to be both dedicated and highly talented. We will most definitely continue to work with Toptal. ”
Savannah de Savary
Founder @ Industry Hub
“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.
