Mat Tomaszewski
Global product design leadership
CV
Hi,
I’m Mat
I’m a product design leader with 20+ years of overall experience. My primary interest is in building outstanding products and spearheading purposeful innovation through thriving, happy teams.
“
From day one, Mat brought a unique ability to merge data-driven insights with strong design sensibility. He never approached design in isolation; instead, he worked hand-in-hand with peers across functions, ensuring that every decision was grounded in both user experience and measurable impact. His creative problem-solving and sharp eye for detail played a key role in driving projects forward and delivering designs that resonated deeply with our users.
I have no doubt that Mat will bring the same passion, creativity, and leadership to any team he joins. He is not only an outstanding design leader but also a trusted colleague and partner. I wholeheartedly recommend him for any design leadership role and am confident he will make a lasting impact wherever he contributes.

I hired Mat to build a world class internal design team for Sector Alarm to take care of consumer App design for second largest home alarm company in Europe (700k+ households) as well as design for all internal tooling, especially seller and installer apps. Mat managed to build a small and extremely capable internal design team in record time, and phased out the contractor designers per plan while doing high quality hands-on design work himself. Testimony of this is the IF Design award that was received for App design as well as app store ratings reaching up to 4.9.
I can safely say that Mat is a fantastic design leader capable of leading small and bigger teams. He is also an extremely talented hands-on designer and has a rare gift to carry both roles simultaneously effectively without sacrificing either. Highly recommend!

Mat and I worked together on the new HERE WeGo app. He built and led the design team that created the amazing UX and UI for HERE WeGo. He's not only a great team leader, but also a brilliant designer. I enjoyed the intense discussions about the need for perfect timing of animations, physical effects, proper shadows, smooth map gestures, and much much more. I learned from Mat that attention to these details makes the difference between a great product and an exceptional one.
If you are looking to build up a strong and healthy design team in your organisation that will deliver outstanding results, you should speak to Mat.

Product leaders shouldn’t be numbers people. They should be experts in their subject matter. Or they can be designers, who are able to immerse themselves both ends, deal with the complexities and hold the vision of the whole – way beyond the next quarterly report or the sprint at hand. Mat can. If you see design as an integral part of product strategy, you should work with him.

Mat played a key role in the relaunch of Ubuntu One. With his ability to quickly grasp the essence of service, messaging and positioning strategies, he was able to architect and design a web portal that within a few weeks helped brake our sales and user conversion records.
Mat is a team player, understands how to work in matrix and product development environments and can deliver creative, quality work under pressure. He has been a pleasure to work with.
