Toptal in the press
“Despite accelerating demand for coders, Toptal prides itself on almost Ivy League-level vetting.”
Selina Wang
“Toptal allows corporations to quickly assemble teams that have the right skills for specific projects.”
Steven Norton
Testimonials
“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
“I struggled for weeks with a Youtube API-specific problem and couldn't find anyone to solve it. Toptal immediately identified the right consultant who took the time to investigate the issue and resolve it quickly. The process was seamless and I will continue to use Toptal with any other issues that arise.”
Rohit Gupta
CEO @ Bollyshake
“I’m a big believer in the saying, ‘hire smart, or manage tough’. For us non-hackers, Toptal takes the guesswork out of hiring. Their coders are vetted, and the work is guaranteed. Why look anywhere else?”
Greg Archbald
Founder & CEO @ Greasebook
“We have been incredibly happy with our Toptal experience. Initially a skeptic, the process to find and recruit a fabulous iOS developer was very easy. Rather than sifting through hundreds of CVs, we saw two and hired them. They have worked effectively, getting up to speed incredibly quickly and have almost become part of the team. We would definitely use Toptal again. ”
James O'Day
Co-Founder @ Pearlshare
“We've been very pleased with our experience working with Toptal. Their team was incredibly helpful in helping us find the perfect developer for our project. The work was stellar, the communication was excellent and we couldn't have been happier with the overall experience. We're excited to work with Toptal for more projects in the future!”
Ryan Walker
Director, Product Management @ Rand McNally
“My business relationship with Toptal has been nothing short of terrific. From reviewing my project with their team to choosing a highly-talented developer, and all the way through releasing our application, it has been an incredibly smooth and successful experience.”
Gary Craig
Senior Analyst @ NetApp
“We have been with Toptal for over two years and have hired through them multiple times. They've never failed to deliver with world-class talent and customer service and have been our first choice when scaling our team.”
Stuart Reavley
Product Lead @ ClassDojo
“Toptal helped us when we had a hiring gap we needed to fill. The developer we received was excellent, with a great work ethic and fit in very well with the team. We are very happy with the service and would definitely consider using Toptal again in future should we need additional help. ”
David Gildeh
CEO @ Dataloop.io
“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
“Toptal provides a great service: Within a week of posting my job, I was matched with my developer and ended up completing the entire project with him. I'll continue to use Toptal in the future for any new development work I may need.”
Mike Jones
CEO @ DigitalDripped
“Andrea is doing an amazing job. I don't think we could have gotten a better person. He is fun to work with, he thinks out of the box, and he is extremely knowledgeable in what he is going. He not only does an excellent job, he also helps our company to differentiate our business model further (e.g. making our app offline-capable). I would recommend Andrea as well as Toptal any time to any friend.”
Pascal Girardat
Co-Founder / CEO @ Lifestage Solutions AG
“One of their engineers from Colombia has joined our team as a full-time developer for more than 6 months, sometimes flying to work on-site in New York City with us. He is one of the best developers I've ever worked with.”
Carter Cleveland
CEO @ Artsy
“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”
