"Toptal is killing it, it kind of owns this market."
Andrew Ross Sorkin Reviews Toptal
Cnbc 02e66b
"Tech companies simply cannot find the quality employees they want to hire. The solution: Toptal."
Liz Claman´s Review of Toptal
Fox 7ef901
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
“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
“Chris Wood 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.”
Aaron Titus
Project Manager @ Crisis Cleanup
“Getting set up with Toptal and finding a new team member was so easy, I don't know why anyone wouldn't give it a try. Best of all, we no longer have to worry about finding great people to help with our projects!”
Mike Branch
President & CTO @ HarborSI
“We've been incredibly pleased with our experience working with Toptal thus far. Their team worked quickly and efficiently to isolate the needs of our project, and they paired us with an appropriate developer within a couple days who we quickly contracted after a great interview. The work performed on our project was top-notch, and we can’t wait to make use of Toptal’s resources again.”
Ryan Staake
Owner @ Pomp&Clout
“The developers I was paired with were incredible—smart, driven, and responsive. It used to be hard to find quality engineers and consultants. Now it isn't.”
Ryan Rockefeller
CEO @ Radeeus
“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've actually remodeled the way we do our work to take advantage of Toptal's capabilities. We develop pseudo code with some code fragments and send to our Toptal developer with 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
“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
“Toptal understood our project needs immediately. We were matched with an exceptional freelancer from Argentina who, from Day 1, immersed himself in our industry, blended seamlessly with our team, understood our vision and produced top-notch results. Toptal makes connecting with superior developers and programmers very easy.”
Jason Kulik
Co-Founder @ ProHatch
“We recently launched our app with the help of Toptal and Nikola, an iOS developer. I was immediately impressed with the constant communication, detail, and level of talent that Nikola brought to the table. More importantly, when the project was underway, Nikola proactively provided creative workarounds for unforeseen hurdles and challenges. I couldn't be happier with our engagement and would highly recommend Nikola and Toptal.”
Chip O'Toole
Founder @ Humans Helping Robots LLC
“Ignacio is one of the most diligent software developers that we have ever worked with—we feel like he's part of the family. He has always been flexible enough to work on our team's schedule and never misses deadlines. Toptal gets you the talent you need, on your timeline, keeping the process very low friction.”
Austin Evarts
CEO @ GoChime
“Through Toptal, we were able to find and select a senior engineer who is both very professional and easy to work with. The quality of matching that Toptal enabled has been crucial to our success, it was at a fair price, and it came with a much appreciated, risk-reducing trial period.”
John Olsen
Director @ Bingo Solutions
“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.”
