Testimonials
“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
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin
Chief Technologist and Co-Founder @ PriceBlink
“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
“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 am more than pleased with the experience with Toptal. It may cost a little more, but because they pre-qualify and hand-pick the professional best suited for the job, it's well worth it. The professional I got to work with was on the phone (Skype) with me within a couple hours. I knew after discussing my project with him that he was the candidate I wanted to do the job, and I hired him immediately... and he wasted no time in getting to my project. He completed the job and went the extra mile to clean up older, messy code and even added some great design elements that enhanced our overall look. I would highly recommend Toptal to anyone needing to hire a professional. Great company. Great service. Thank you, Toptal.”
Paul Fenley
Director @ K Dunn & Associates
“Toptal offers a no-compromise solution to businesses undergoing rapid development and scale. Every engineer we've contracted through Toptal has quickly integrated into our team and held their work to the highest standard of quality while maintaining blazing development speed.”
Greg Kimball
Co-Founder @ Nifti
“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
“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 @ HarborSI
“Back in July '12, FundedByMe needed to quickly scale our development team to create the equity crowdfunding leg of our operation. Working with a small budget, we couldn't spend time on vetting candidates, so we turned to Toptal. They identified a stellar developer that truly set the bar when it came to delivering product.”
Arno Smit
CTO @ FundedByMe.com
“We were extremely impressed with both Toptal and our developer, Bojan. They were extremely professional and flexible with our schedule. On multiple occasions, we needed to alter our timeline and they never hesitated to accommodate us. Bojan was communicative and delivered what we asked for on time and exactly to spec. I know that should we need additional work, will surely be looking to hire Bojan and Toptal again. ”
Stephen Vasallo
Co-founder @ Bubble
“Prior to working with Toptal, we had a very difficult time finding qualified developers. The Toptal team worked with us to find a developer that was a great fit in terms of technical skills, culture, and finances. Our Toptal developer is four months into this project and we are still impressed with the attention to detail and technical prowess that he brings to our team.”
Justin Fister
Chief Scientist @ PaperRater
“We've been incredibly pleased with our experience working with Toptal thus far. Their team worked quickly and efficiently to isolate the needs of our project, and they paired us with an appropriate developer within a couple days who we quickly contracted after a great interview. The work performed on our project was top-notch, and we can’t wait to make use of Toptal’s resources again.”
Ryan Staake
Owner @ Pomp&Clout
