Within 8 business days of our first conversation, we had highly skilled and reasonably priced Toptal developers working for us. It has been an empowering experience for our company to start working with Toptal.”
Chris Clark
CEO @ BirdieFire
“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
“Chris is an absolutely exceptional Python developer, and the single most efficient programmer I've ever worked with. From the beginning of the project, Chris was instantly a vital member of the team. He's proactive, self-managed, knowledgeable, and efficient. I point him in a direction, and he delivers. Chris will be a part of the Crisis Cleanup team as long as I have anything to say about it.”

Laurent Alis
Founder @ Livepress
“We were extremely impressed with both Toptal and our developer, Bojan. They were 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, we will surely be looking to hire Bojan and Toptal again. ”
Stephen Vasallo
