Space is not absence. It is possibility. Most studios stand in more of it than they can see.
That space is where I work.

The work is clarity. Performance is more than output. It is how a studio decides, communicates, and holds its best work together as it grows.


My name is Bastiaan van der Sluis. Architecture, public relations, leadership, entrepreneurship. Each showed me where high-performance work happens and where it fractures, inside MVRDV, BMW, DIESEL, Studio Roosegaarde and KCAP.


The studio stays at the centre, never my method. No standard programme. I find the small improvements that compound, with results soon enough to build momentum.


The work is stepping into someone's tornado.
Feel the pressure from the inside, then show them what they cannot see while standing in it. Like a race engineer on the pit wall. You drive. I make sure the system lets you win.


One question focuses everything. How do ambitious studios keep clarity as they scale? DON'T WASTE I™ is my answer. The name is an instruction. Don't waste intelligence, talent, time, energy. The "I" is you. Clarity, only the signal. Endurance, built to hold. Performance, a system, not a personality.


Think in Spaces.
Create Space. Design Performance.

DON'T WASTE I™ is an embedded performance practice for ambitious creative studios. Founded by Bastiaan van der Sluis, the practice works beside the founder, inside the pressure, rebuilding how the studio decides, communicates and shares responsibility so the work grows at full speed without breaking the founder or the team. Based in Rotterdam. Operating across Europe.
