Testimonials
“The best talent is at Toptal for sure. It's way better and faster than any other means of getting top talent.”
“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.”
“We really enjoy working with Toptal. The experience has been very positive, and we'd recommend it to anyone seeking developers on-demand.”
“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.”
“Toptal has provided us developers for a wide range of projects. They are quick to provide candidates, and always very quick in communication. We have been happy with the quality of work from the developers as well as the Toptal representatives. Highly recommend!”
“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.”
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
“Toptal provides a great service: Within a week of posting my job, I was matched with my developer and ended up completing the entire project with him. I'll continue to use Toptal in the future for any new development work I may need.”
“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.”
“Toptal helped us achieve our goals by really understanding what we were looking for. They worked with us very closely to figure out what the right talent looked like -- from a technical, cultural perspective -- and helped us get the onboarding done quickly so the talent could be effective as soon as possible. ”
“Toptal's developers and architects have been both very professional and easy to work with. The solution they produced was fairly priced and top quality, reducing our time to launch. Thanks again, Toptal.”
“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”
“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.”
