      Product Design Review from Manuel Colom

      Working with ANML on the Yummly app experience and the Yummly Smart Thermometer (IoT) was an outstanding collaboration. Yummly combined personalized recipe discovery, meal planning, and guided cooking into a highly curated food experience, while the Smart Thermometer extended that ecosystem into connected cooking with real-time temperature tracking and assisted preparation workflows. As Director of UX at Yummly, I worked closely with ANML throughout both initiatives, and they operated almost as a seamless extension of our internal design team. Their work consistently demonstrated excellent design craft, strong product thinking, and a highly collaborative mindset. Beyond delivering high-quality UX and visual design, their contribution helped sharpen and strengthen the overall value proposition of the products by making complex cooking experiences feel approachable, premium, and intuitive for users.

      Web Design Review from Nathan Thornburgh

      As Anthony Bourdain's partners, we were approached by CNN to create an immersive digital site that would provide a beautiful home for each destination covered by Bourdain's show Parts Unknown. It was a huge task not least because there were already close to 100 destinations to integrate into a usable global site. But also because the site was meant to live up to the beauty and aesthetic of the television program. And it needed to be done in a way that satisfied both our mainstream luxury advertisers (like LandRover, ANA, and more) but also the famously high standards of Bourdain himself. ANML engaged in this 18-month design and build process with outstanding workmanship and creative decision-making. They navigated wildly different and demanding stakeholders. And in the end they built a site that still looks fresh even nearly a decade later. If you want to make lasting work, there is no one else I could recommend more.

      Web Design Review from Alex Lacerda

      We partnered with ANML to evolve our digital experience in a way that stayed true to our brand while modernizing how we present our products and story. As a company with a long history in music, it was important to find a partner who could respect that legacy while helping us move forward.ANML took the time to understand our brand, our audience, and the role our products play for musicians. They built on our existing foundation and translated it into a more cohesive and intuitive experience that better reflects who we are today.Their team brought strong thinking across UX and design, helping us improve how content is structured, how products are presented, and how users navigate the experience. The collaboration was smooth and highly responsive throughout.The end result is a more polished and modern experience that still feels authentic to our brand. ANML was a thoughtful and reliable partner, and we would highly recommend them.

      Web Design Review from Alyssa Brenke

      Specifically, working with Ben was amazing! He was incredibly responsive and answered all my questions throughout the process of updating our website. Our original site was built roughly a decade ago (or longer) so we were in need of some streamlining and modernization. The team did just that and quickly! The first iteration was spot on for what we were looking for. Not to mention, they were able to launch quickly and without any interruption to our daily operations. Would 100% recommend [it]!
