We're here to empower creative professionals and their businesses to reach new heights through strategic growth, continuous improvement, and clear communication so they can better inspire others.

  • Holistic Approach

    Creativity isn’t chaos. It’s a balance of the mind, the mission, and the method. A holistic approach means zooming out to see the full picture—habits, culture, strategy—and designing a path that aligns everything. No wasted motion, no scattered focus. Just purpose, clear as day, guiding every step.

  • Creative Performance

    Performance isn’t reserved for athletes. It’s the unspoken discipline behind every stroke, every decision, every push toward something better. It’s a system—a rhythm—where ideas flow and obstacles crumble. True creative performance doesn’t just happen. It’s earned through clarity, balance, and the sharp edge of knowing you’re moving forward with purpose.

  • Ecosystem Thinking

    Everything connects. Your tools, your team, your time. Like roots beneath a forest floor, every part of your ecosystem feeds the next. Break one link, and the whole system feels it. But when the connections work—when flow replaces friction—creativity doesn’t just survive. It thrives, seamless and strong.

  • Continuous 1% Improvements

    No fireworks. No overnight transformations. Just small, deliberate steps—day in, day out—that add up to something staggering. 1% better every time. In habits, workflows, ideas. That’s the quiet art of progress: unseen by most, but undeniable in its impact. The work doesn’t stop, but neither do the wins.

  • Communication

    Stories aren’t just told; they’re heard, felt, and remembered. Communication is the art of cutting through the noise and making your voice hit where it matters most. It’s a tool, a weapon, and a lifeline for those with something to say. Because the difference between being ignored and inspiring change? That’s communication done right.

  • Human Capital

    The heartbeat of creativity is people. Ideas don’t just appear; they’re nurtured by minds that need clarity, space, and purpose. The architect sketching at dawn, the writer lost in their thoughts, the team grinding at midnight—human capital is the fuel. Invest in people, and you don’t just get output. You get breakthroughs, resilience, and a culture that breathes ambition.

Founder: Bastiaan van der Sluis
With 15 years of experience across architecture, fashion, art, design, and communications, I’ve worked with renowned names like MVRDV, Studio Roosegaarde, KCAP, and BMWi, in both design and communication leadership roles. At 33, I became the Director of Communications at the internationally acclaimed architecture and urban design firm KCAP, founded by Kees Christiaanse (RIBA Fellow).


In 2024, I founded Don’t Waste I, driven by a passion to help others harness their creativity and communicate their unique value to the world. Alongside this professional journey, I’m also the proud father of two—a daughter and a son—who remind me daily of the importance of purpose and balance.
