Testimonials
“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
“We really enjoy working with Toptal. The experience has been very positive, and we'd recommend it to anyone seeking developers on-demand.”
Jeff Kerr
CEO @ CaseFleet
“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
“Dave as a developer was absolutely fantastic! The guidance that he provided us will allow us to make tremendous improvements to the next version of our application.”
Baroni Parson
IT Manager @ City Real Estate Advisors, Inc.
“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”
Mindle Hastings
Sr. Product Manager @ Bodybuilding.com
“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
“Toptal was the best thing to happen to my web app. Initially, I hired a team of freelancers from India through another freelancing website—which was a nightmare. In fact, it was so bad that I had to start again from scratch, which is when I found Toptal. The experiences were like night and day. It was so refreshing to get partnered up with a quality developer that I could trust due to Toptal's extensive screening process. I will only use Toptal from now on and highly recommend you do the same.”
Chris Holtzhauer
CEO @ HootRecruit
“We had a wonderful experience with our Toptal consultant. He was very reliable and punctual, delivering excellent work on a budget—we will certainly be using him again!”
Barbara Karpf
President @ DecoratorsBest
“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
“Finding a good developer who specialised in the technologies we use seemed like an impossible task... until we used Toptal. We had several trial periods and have just accepted our first developer to join the team! The whole process went seamlessly and without any surprises or hidden costs. We are very happy and will continue to work together!”
Artem Tolmachev
CEO @ eKids.nl
“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
“Toptal has helped my business tremendously by finding, vetting, and recruiting the talent I need, at the right time. I’d definitely recommend it to others.”
Xavier Xicay
CEO & Creative Director @ Tuatara Corp
“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.”
