Testimonials
“We've had multiple needs for various development talent and Toptal doesn't disappoint. They truly focus on matching the best developer to our specific engagements, and they continue to stay connected in an effort to exceed our expectations at all times”

“With the pressure on and millions watching the Cleveland Cavaliers during the NBA Playoffs, Toptal delivered the talent and expertise needed to launch a brand new fan engagement platform.”
Conor Kenney
Director of Professional Services @ Cleveland Cavaliers
“We're a small firm with big dreams. After trying 4 or 5 local or outsourced developers, we were out of options. I'd heard of Toptal, but was worried that my company wasn't big enough for them. After calling them up, I found out that I didn't need to meet any minimum budget and was immediately put in touch with a developer to talk through my problems and goals. A day later, he got back to me with a list of possible solutions. After 9 months and 5 developers, Toptal got me my solution in a single week at a price I could afford.”
Kevin Ramirez
Co-Founder @ SixtyVocab.com
“Dario was recently assigned to our company in order to help with PHP and JW Video player refinements. He listens extremely well and offers common sense suggestions that save both time and money. He speeds up the process by asking great questions, and he just delivered our first project on time. His redesigned player offers a very pleasing appearance and delivers functions that are both elegant and intuitive.”
Dennis B. Jacobs
President @ College TV Ticket
“Toptal developers deliver. Hiring my first developer on Toptal was such a pleasant experience that I quickly turned around and hired another. Every developer I've hired on Toptal has been professional, skilled, and self-managing—a pleasant departure from the typical freelancer marketplace.”
Mike Riess
Owner @ RiessGroup

“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
“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 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.”
