Testimonials

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.
Edward Daniel, Co-Founder

I've worked very closely with Martina for over a year and have to say she is one of the best people I have ever worked with. Instead of simply following instructions blindly, she thinks through the task at hand, becoming a thought partner to help with whatever the project may be. Besides being super talented at design, she possesses specific qualities that make her exceptional to work with given the fast paced nature of being a startup. I would definitely recommend her to anyone looking for a talented, professional designer who doesn't need much direction to hit the ground running.
Sahil Khanna, Sr. Manager, Marketing
LeanTaaS, Inc.

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.
Rich Danker, Founder
Prose Market

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.
Michelle Krogmeier, Project Manager

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.
Ethan Brooks, CTO
Langlotz Patent & Trademark Works, Inc.

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.
Thierry Jakircevic, General Manager, Digital Solutions, Bridgestone Head Office, Tokyo
Bridgestone Corporation

We had an amazing experience working with our Toptal designer. In only two weeks, we accomplished what would've taken most companies 3 months to complete. We also enjoyed working with the Toptal team to make sure we were paired up with the right designer that would fit both our company culture and working style.
Ted Blosser, Head of Sales and Customer Success
WorkRamp

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.
