Turning your vision into products people love.

 
 
 

Build what matters. Launch what leads.

ViableThings is the design and innovation studio of Stefan Van Cleef. I help founders, start-ups, and scale-ups turn ideas into products and brands that matter. From first sketch to market traction, I design with purpose and impact. When needed, I bring in trusted collaborators, so together, we can build what’s next.
