    ANML Reviews & Testimonials

    • Manuel Colom
      Manuel Colom UX Director at Yummly
      5.0 ★

      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.

      Mobile App Development Review from George McKerrow

      ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.

      Web Development Review from John Riley

      ELEK+RIK was tasked with creating a website for our company from scratch. They were professional, communicative, and dedicated to delivering an exceptional website that perfectly captured the essence of our company while exceeding our expectations. They are a talented, reliable, and customer-focused web design and development company that I would highly recommend to anyone.

      Small Businesses Website Development Review from Kris Meyer

      Austin rebuilt our website from the ground up and helped turn Bespoke Tint & PPF into one of the top tint brands in Bellevue. The work started with a full redesign of our website, including branding, copywriting, conversion improvements, mobile optimization, and development. The new site immediately performed better and generated more leads after launch. After the website launch, we continued working together on SEO, AI search optimization, paid advertising support, analytics, A/B testing, and ongoing marketing strategy. He also helped improve our review visibility, local search presence, and overall positioning online. What started as a website project became an ongoing growth partnership focused on increasing traffic, leads, and customer acquisition.
