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’m a big believer in the saying, ‘hire smart, or manage tough’. For us non-hackers, Toptal takes the guesswork out of hiring. Their coders are vetted, and the work is guaranteed. Why look anywhere else?”
Greg Archbald
Founder & CEO @ Greasebook
“John has been so great to work with! He has met all our requirements, done a speedy job with excellence, and has completed everything we’ve asked him to. Working with him has been a great experience.”
Jenny Lord
Communications Project Manager @ Lake Pointe Church
“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
“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
“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
CEO @ TSOLife
“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
“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
“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
“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
“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
“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
“Toptal provides a great service: Within a week of posting my job, I was matched with my developer and ended up completing the entire project with him. I'll continue to use Toptal in the future for any new development work I may need.”
Mike Jones
CEO @ DigitalDripped
“Working with Enrique has been a pleasure and a relief. His knowledge in the IT space is broad and in-depth. Zoomedia has been in need of this level of support for some time and I feel confident we are an exponentially stronger team with Enrique on board.”
