“Rafael is an amazing designer. His aesthetic sense is spot on, and he seems to be able to anticipate our needs before we even know what they are. He's taken the time to understand both our company and our clientele, and his solutions are consistently in-line with our values, interests, and our customers' needs. He delivers on time (if not earlier), works quickly, is well organized, and very effective. He's a pleasure to work with, and we're very happy to have found him through Toptal.”

“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!”

“Dean blew us away. He ranks right up there as one of the top five designers of the hundreds I have worked with in the past. He listened, was totally professional, and came up with a 3D rotating cube design completely on his own. We didn't even ask for it, and yet it has become the centerpiece of our app and how users engage with it right off the bat. What he produced inspired all of us at Votify, and put us on track for launch and investor funding.”

“The best talent is at Toptal for sure. It's way better and faster than any other means of getting top talent.”

“Michael is an incredible designer, and has been a great fit for our project. He just gets it in a way that can’t be taught. My goal was to pay Toptal to find me a high quality designer for my project, and that is exactly what happened. It was easy. Being able to see the portfolio work on Toptal’s platform is what gave me the infomation I needed to choose Michael. I have nothing but good things to say about Toptal and am looking forward to using Toptal for other projects in the future.”

“I couldn’t have been more pleased with Toptal. They are professional, quick, well priced, and fun. I will be using them again for my next project, and the next, and the next, and the next ... ”

“Always incredibly responsive, prompt, and flexible, Anna has done an outstanding job -- her work is exactly what we needed. Toptal has been a great experience for us due to the ease of getting a project going with quality talent at a cost that fits our budget. The automated online system for managing everything during onboarding was also impressive.”

“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.”

“What attracted us to Toptal was that Toptal is sourcing its talent from a global pool. The selection process is very stringent. They’re sourcing the talent not only based on capabilities -- sourcing the best 3% -- but also based on cultural fit, which is really important to us. We had an amazing experience working with Toptal. Toptal helped us achieve our goals by bringing us very high-quality resources, on very short notice.”

“Toptal gave us access to the best designers out there. They’re not easy to find. Those designers integrated very quickly with our existing teams. They very quickly understood our business case and the value of our solution. Toptal really allowed us to focus on building the best possible product and save a lot of time on the typical administrative pains that goes with it -- specifically, finding the best talent. Toptal designers were very responsive, always online -- and that made life very easy for us. We have ambitious goals on how to grow the application and already Toptal has been a key contributor to that success.”

“Carlos has the unique talent of blending both quantitative and qualitative research to keenly identify UX challenges and opportunities. He thinks methodically, emphatically, and holistically to produce data-driven strategies and well-executed designs. Over the past 8 years of working with fully or partially distributed teams, Carlos manages working remotely far better than anyone I've encountered because of his strong communication and presentation skills. He is the first on my list the next time I need a UX designer.”

“Darko did a great job figuring out the user architecture for our concept, which led him to produce terrific wireframes. His knowledge of usability and design was a perfect match for the outside voice we needed to help jumpstart our project. We would certainly recommend him and work with him again in the future.”

“One of our 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 applications, interview and test the applicants' capabilities, 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, and hire with a risk-free trial -- much faster, a lot easier, and with incredible results.”
