About ONESTONE

“You can’t solve a problem with the same consciousness that created it. You have to learn to think anew.”
— Albert Einstein.

At OneStone, we believe the real magic happens before the solution. We’re here to help founders, leaders, and teams see their challenges with fresh eyes—so you can solve the right problem, not just the obvious one.

What We Do:
 OneStone offers strategy and creative direction for start-ups, scale-ups, established brands, and turnarounds (“grown-ups and fuck-ups”). Our unique process, inspired by Einstein’s philosophy, dedicates time to deeply understanding your challenge—then delivers clear, actionable solutions that drive long-term growth.

How We Work: 
Inspired by Einstein’s philosophy, we spend more time understanding your problem than anyone else—because that’s where the value is. Our sessions are fast, focused, and designed to get you unstuck and moving.

Our Offer: Fire Stone Session (Free): For when you’re stuck, need a second opinion, or just want to talk. No strings attached.

One Stone Session (€3,000 - €6,000): Deep-dive strategy and creative direction in a single, high-impact session, plus a written General Creative Brief.

Gem Stone Session (€15,000 - €20.000): The full transformation—brand guide, naming, logo, house style, and creative communication. (Websites available as an add-on.)

Why OneStone?
 Because one well-placed stone can change the course of a river. We don’t do endless decks or vague workshops. We deliver clarity, direction, and creative solutions that move the needle.
