Testimonials
“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

Vineet Singal
Co-Founder @ CareMessage
“We needed a programmer to help push a project over the finish line, and I figured -- best case -- Toptal would find someone who would come in and complete a few tickets. Instead, Sergio blended right in with the team and made significant progress after mere days of ramp-up. He even offered to take his laptop with him on vacation in case we had a customer issue with his code! He surpassed my expectations, and then some.”
Bryan Adams
CTO @ Healthsense
“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
