Testimonials
“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

“It has been wonderful to work with Fabian for the past two years. He is an expert in JavaScript development and has built our embeddable widget and video player. He is a quick study and is able to learn how to integrate new technologies, which is so critical for a startup. He even took the extra effort to teach others on the team. He is super responsive and often went above and beyond to help us meet deadlines (including working on weekends). Thank you Fabian. Thank you Toptal for making it so easy to find and work with amazing talent.”
Natasha Mohanty
CTO @ FEM Inc
“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
