Testimonials
“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
“Toptal has been an incredible source of amazing software engineering talent. The contractors who have worked with us have been top notch, spoke perfect English, and worked superbly with our team. We recommend Toptal without any reservations!”
Vineet Singal
Co-Founder @ Anjna Patient Education
“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 had a great experience with Toptal. They paired us with the perfect developer for our application and made the process very easy. It was also easy to extend beyond the initial time frame, and we were able to keep the same contractor devoted to the project. We definitely recommend Toptal for finding high quality talent quickly and seamlessly.”
Ryan Morrissey
CTO @ Applied Business Technologies, LLC
“Working with Toptal has been a great experience. Prior to using them, I had spent quite some time interviewing other freelancers and wasn't finding what I needed. After engaging with Toptal, they matched me up with the perfect developer in a matter of days. Amaury, the developer I'm working with, had all of the right skills and experiences that I needed for my project. He not only delivers quality code, but he also makes suggestions on things that I hadn't thought of. It's clear to me that Amaury knows what he is doing and I'm happy to have him on the team. Highly recommended!”
George Cheng
CEO @ Bulavard, Inc.
“Back in July '12, 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
CTO @ FundedByMe.com
“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
“Toptal is a great resource for startups with ever changing product roadmaps and budgets. We had highly skilled and reasonably priced Toptal developers working for us within 8 business days of our first conversation with Toptal. It has been an empowering experience for our company to start working with Toptal.”
Chris Clark
CEO @ ModernStat Labs
“Toptal has been extremely helpful to us in finding top remote talent. The ratio from interview to hire with Toptal candidates is the highest I've ever experienced in my professional career.”
Philipp Berner
Co-founder and CTO @ KeepSafe
“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
“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.
“We needed some short-term work in Scala, and Toptal found us a great developer within 24 hours. It was done quickly for a specific need, and it's been great. It simply would not have been possible via any other platform.”
Franco Arda
Co-Founder @ WhatAdsWork.com
