As part of Munich‘s Venture Lab Software/AI, the jointly-established hub for leading AI startups by TUM and UnternehmerTUM, Sizekick gained valuable early access to a network of experienced founders, consultants, and partners.

When Sizekick’s founders Jake Lydon and David Oldeen shared their vision and told me about their plans for the product for the first time, I was impressed by their extensive domain knowledge and clear strategy on how to solve a big problem for users, shops, and the environment. I look forward to seeing Sizekick’s impact on the fashion industry grow.

The founding story

Jake Lydon (USA) and David Oldeen (Germany) first got to know each other while working together at Presize, where they aimed to solve one of fashion e-commerce’s biggest challenges, namely unnecessary returns.

Jake developed the industry-leading AI system that enabled users to shop online and get both accurate body measurements and great size recommendations - with just a smartphone!

David led Presize’s commercial growth and scaled the state-of-the-art sizing solution’s impact on the fashion industry by onboarding a large number of partner shops.

Shortly after Presize was purchased by Meta (the company behind Instagram & Facebook) in 2022, Jake & David decided that their “sizing journey” wasn’t over and Sizekick was born. They are focused on building the next generation of sizing technology and making it available to fashion brands and retailers, with the goal of eliminating size frustration and reducing returns.

With strategic partner Hohenstein at their side and a top-notch team operating out of Sizekick’s Munich HQ, the new Sizekick size advisor was launched in record time in 2023.
