Mustard Navy Reviews 9

We worked with MustardNavy on the UX and UI design of an AI evaluation product, starting from a technically solid prototype with complex user interactions. Their guidance helped surface and address design challenges we hadn’t fully considered, resulting in much clearer interactions and effective UI solutions. They were proactive, creative, and consistently focused on simplifying the user experience in an engaging way, while staying true to the product itself. The team quickly aligned with our product vision, constraints, and design taste, delivering significant results in a short time. They concluded the work with a logo design that truly nailed it, reflecting a deep understanding of the product and its core aspects. Overall, MustardNavy delivered a full and well thought end-to-end user experience design, and we would highly recommend them to anyone looking to provide high-quality UX to their users.

Great experience working with Mustard Navy on redesigning our app from scratch. I feel they understood what we were after and struck the right balance between suggesting new ideas and sticking to what we had already thought about. Very smooth and efficient process overall. Looking forward to seeing the app out there now.

As a young startup, we were looking for help with fundamental questions such as "How should we design our product so that it triggers a WOW effect among our potential customers?" Mustard Navy did a great job with this task despite the remote setup.

I have worked with Tom for 4 years across different ventures and I can wholeheartedly say he is the best Product Designer I have ever worked with. He can be highly strategic, amazing researcher and also quick visual designer when needed. Extremely versatile personality and skill set. I fully recommend his agency.

Exceptional Product and UX Design Partnership!!

We had the pleasure of working with Mustard Navy on the design and development of the next phase of our platform. From the very first conversation, their team lead by Tom demonstrated a deep understanding of both product strategy and user-centered design, making them a true partner in every sense.

Strategic Thinking: Tom and team didn’t just “take orders”—they challenged assumptions, asked the right questions, and brought insights that fundamentally strengthened our product direction. Their ability to align design with business goals was a game-changer.
User-Centric Design: Their UX process was rigorous, thoughtful, and data-informed. From user research to prototyping every decision was clearly grounded in creating value for our users. The end result is an interface that’s not only elegant, but genuinely intuitive and enjoyable to use.
Collaboration & Communication: Tom is great to work - the team integrated seamlessly with ours, bringing a collaborative mindset and clear communication that made the whole process feel smooth and transparent. They respected timelines, welcomed feedback, and were always responsive and proactive.
engineering team.

I wouldn’t hesitate to recommend them to anyone looking for a world-class design and product partner.

Tom and his team have been a fantastic product development partner for our AI for Marketing start-up. My two founders and I are in full-time day jobs and haven't been here before so there was no way we'd have got so far, so fast without Mustard Navy.

Tom has a brilliant vision of how to see the way forward, what's worth working on, and gets it done. He draws on his own extensive experience in businesses and as a consultant to other businesses.

He's really nice to deal with too which has made the project fast and easy.

Thanks Tom

After evaluating several agencies, Mustard Navy stood out for their thoughtful and practical approach. They met us exactly where we were as a scale-up, while bringing the expertise you'd expect from a team working with large corporates. What impressed me most was their ability to understand our unique challenges and translate them into practical solutions. The team is genuinely nice to work with, and their focus on customer needs helped us avoid costly mistakes down the line. Would highly recommend them for any product, service, and visual design challenges.

Working with Mustard Navy nudged us further into a user-first approach, instead of a more dev-led approach. While scary at first, we quickly realised this was the way to go.

Irrelevant “nice-to-haves” became easier to identify and deprioritise, while Tom and the team were able to identify countless meaningful design wins for our customers' experience.

We also accelerated our development timelines by focusing on what matters most to our users - simplicity.

If you are staring into the void of your product roadmap and curious about AI and Design, talk to Mustard Navy.

We're building our Scope 3 decarbonization platform and MN provided substantial product and design contributions.

 It's not just advice and wisdom from years in the field of AI; it's hard artifacts that continue to anchor our product development months after the projects: user research & synthesis, service blueprints, design frames.
