Within our Research Management team, you have the opportunity to validate innovations for leading brands, such as BSH, Louis, Yello, Hansgrohe, ALH Group and many more. You’ll get to shape the state‑of‑the‑art validation method for innovation and product development.

WHAT YOU’LL ROCK

• Product mockups – design product images and mockups according to the given MVP brand or client inputs for different testing variants, using AI tools or agents
• Brand design – create desirable brand assets from logo, to color themes, to typography for the idea to be tested
