Sergey Bertagnini designs digital and physical products that make sense at first glance.

Most startups juggle a designer, a developer and a 3D studio, and lose weeks between them. I'm one partner from first idea to launch: the product, the website that sells it and the 3D that makes it real.

My story

I'm Sergey , a design partner based in Turin. Founders usually find me when their product, website and brand are made by different people and stop telling the same story. I design and build all three with you, and I only take two clients at a time, so you always get me and not a team.

It started with graphics at 17 on my first computer, then UI/UX, then transportation design, where 3D and physical products became part of the job. Today I take whole projects from the first sketch to the shipped product.

Away from the screen I play tennis most mornings, and I'm still trying to get a little better every season.
