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 struggled for weeks to find a developer or architect with expertise in a niche API, but to no avail. When we linked up with Toptal, they connected us with the very expert we needed, and a week later we were hard at work making progress! The whole process was very smooth and we ended up with a new feature we couldn't have done without Toptal.”
Thomas Honeyman
COO @ FindMySong
“When you're growing quickly and your internal resources are strapped, you need to find a way to move forward regardless. We couldn't have done it without Toptal. From content creation to programming and design, we were able to leverage the expertise of Toptal's network to move even faster that we could have otherwise. They prioritized finding us the right person, not just a person. Every single one they introduced us to was not only qualified and professional, but also eager to help us.”
Josh Leskar
Manager @ Udemy
“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
“I can't say enough about how happy and confident I am in working with Enrique. He brings an enthusiasm to his profession that is very refreshing, constantly surprising us with his depth of knowledge and his capability to not only complete the task, but to surpass our expectations. He presents us with solutions that we would not have thought about ourselves, and sees the problem better than we can explain it.”
Chad Berryman
Senior Technical Lead @ Zoomedia
“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 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
“I'm incredibly impressed with the caliber of the Toptal developers I have worked with - they have proven themselves to be both dedicated and highly talented. We will most definitely continue to work with Toptal. ”
Savannah de Savary
Founder @ Industry Hub
“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
“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
“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
“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
“It has been wonderful to work with Fabian for the past two years. He is an expert in JavaScript development and has built our embeddable widget and video player. He is a quick study and is able to learn how to integrate new technologies, which is so critical for a startup. He even took the extra effort to teach others on the team. He is super responsive and often went above and beyond to help us meet deadlines (including working on weekends). Thank you Fabian. Thank you Toptal for making it so easy to find and work with amazing talent.”
Natasha Mohanty
CTO @ FEM Inc
“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
“In our 2 years of operations this is by far the most enjoyable and productive working relationship we have had with a developer. I plan on continuing to recommend Toptal's services to other entrepreneurs I run into.”
David Sawyer
CEO @ TSOLife
