Conor Kenney
Director of Professional Services @ Cleveland Cavaliers
“To take advantage of Toptal's capabilities, we actually remodeled the way we do our work. We develop pseudo code with some code fragments that we send to our Toptal developer, who has a specific task set. The work is then further processed by the next group of Toptal engineers. It's been very efficient and we've seen a massive improvement in our development speed.”
William North
CTO & Co-Founder @ Swizly

“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
