DON'T WASTE I™ is an embedded communication performance partner for ambitious creative studios.
Bastiaan van der Sluis 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.
Like a race engineer on the pit wall.
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.
Only the signal.
Built to hold.
A system, not a personality.
Studios accept chaos as the price of creative work. It isn't.
There is an operating space inside pressure and ambition where high-quality decisions get made. I call it Headspace.
I work inside your studio. From five focused sessions to full embedding across teams.
How a partnership runsThe same method as an app. It reads your studio, shows where work, time or money leaks, and gives you the next step each day.

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 help you see where you're actually headed, then build the focus and structure to get there, even while everything keeps moving. Small improvements 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.
I'm fascinated with reading spaces most people walk past, the moment where potential and a void look identical, and the only difference is what happens next. Fix what's broken. Protect what matters. Improve what matters. Not because ambition was missing in the room. Because the conditions around the people never got designed.
