Selina Wang

Steven Norton
“The task of finding and hiring the right developers and programmers can be daunting, especially for startups. After sifting through countless unfit freelancers, we came across Toptal. They were able to fill our open position in no time, and I'd highly recommend the service!”
Josef Holm
CEO @ Tubestart
“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

Xavier Xicay
CEO & Creative Director @ Tuatara Corp
“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
“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
“I needed help, and fast. I did not want to hire a random coder I met online- I was worried about security, and many other issues. Toptal was there when I needed them- and has been fantastic to work with. Outsourcing is full of terrible stories- Toptal is the story that is the giant exception. I give them my highest recommendation.”
Michael Feder
Founder & CEO @ PrayerSpark

“Working with Marcin is a joy, I can't find a better word.

Oh and he has the same sense of humour as me. ;)”
