"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
“Working with Enrique has been a pleasure and a relief. His knowledge in the IT space is broad and in-depth. Zoomedia has been in need of this level of support for some time and I feel confident we are an exponentially stronger team with Enrique on board.”
Justin Bane
Senior Technical Lead @ Zoomedia
“Toptal is amazing! Sourcing and interviewing candidates has always been incredibly cumbersome and difficult - and usually takes weeks or months to find the right people. With Toptal, we had 5 candidates in 2 days that were all perfect for the job. They made the scheduling of interviews easy and straightforward and we were working with a top-level bad-ass developer within 2 weeks. I love you, Toptal.”
Ian Fosbery
“I've been very happy with Juraj. He is efficient, writes great code, and is an extremely nice guy to work with. Most importantly, he is self-motivated. In just his initial pass at the code base, he has contributed several optimizations and stability improvements. Regarding Toptal as a service…well, you matched us up with Juraj without me having to sort through a list of candidates, so I’m impressed.”
Matt Cotton
Dev Team Lead @ eFolder
“With Toptal, we are able to find talented developers in a matter of weeks instead of months. The quality of talent they supply is extremely high as the developers are able to immediately onboard and ramp incredibly fast.”
Zac Carman
CEO @ ConsumerAffairs
“One of our biggest and most time consuming problems is finding qualified staff. We need to find the correct platform to advertise on, create a proper ad, filter through tons of useless applications to try and find the small gems, interview and test the capabilities of applicants to see if they fit our profile and finally take a risk by hiring. This was the old way of doing things! The new way: describe the job position to our Toptal account manager, interview a few qualified applicants, hire with a risk-free trial! Much faster, a lot easier and with incredible end results.”
Catalin S. Balaci
Owner @ EvoBits Information Technology SRL
“Toptal’s ability to rapidly match our project with the best developers was just superb! The developers have become part of our team, and I’m amazed of the level of professional commitments each one of them have demonstrated. For those looking to work remotely with the best engineers, look no further. Thank you, Toptal.”
laurent Alis
Founder @ Livepress
“We used Toptal to hire a developer with extensive Amazon Web Services experience. The process was quick and effective. We interviewed four candidates one of which turned out to be a great fit for our requirements. We plan to use Toptal again in the future and would recommend their services.”
Abner Guzmán Rivera
CTO and Chief Scientist @ PhotoKarma, Inc.
“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
“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
“We've used Toptal developers multiple times for multiple projects, and they've always been world-class—regardless of whether they've been from South Africa, Brazil, or the United States.”
Alex Haro
CEO @ Life360
“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
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin
Chief Technologist and Co-Founder @ PriceBlink
“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.”
