Ek deliberately sets the most uncomfortable quantifiable target he can imagine and then works backward within it as a constraint. When committing to fund European moonshots, he chose one billion euros not from a bottom-up calculation but because it was the most uncomfortable number he could picture; he then asked what it would have to look like and what could be done with that constraint. This mirrors how he treats creativity generally, believing constraints unlock rather than limit it, and how the most creative people are often highly scripted. He frames the approach as a preference for the uncomfortable lane, where a venture either becomes big or yields lessons worth discussing later, rather than the safe lane.
Origin
Ek used the method to size his one-billion-euro commitment to European moonshots, deliberately picking the most uncomfortable number he could imagine and reasoning backward.
Core principles
- 01A big audacious number forces bigger thinking than a comfortable one
- 02Constraints unlock creativity rather than limiting it
- 03Pick the most uncomfortable quantifiable target, then reason backward
- 04Prefer the uncomfortable lane where outcomes are either big or instructive
How to run it
- 1
Quantify the ambition
Express the goal as a single, concrete, quantifiable number rather than a vague aspiration.
- 2
Make it uncomfortable
Choose the most uncomfortable version of that number, one that feels almost too big.
Pro tip Discomfort is the signal that the target will force structurally bigger thinking.
- 3
Fix it as a constraint
Treat the number as a firm constraint to design around, not a soft stretch hope.
- 4
Work backward
Ask what would have to be true and what you could do given that constraint, then build the plan.
Watch out Accept up front that the outcome is either a big success or an instructive failure.
In the wild
Rather than calculating a fund size bottom-up, Ek picked one billion euros because it was the most uncomfortable number he could imagine, then worked out what could be done with that constraint to help European deep-tech leapfrog.
→ He committed a significant portion of his wealth to European moonshots in fields like machine learning, biotech, and energy.
Common mistakes
Setting a comfortable target
A number that feels safe produces incremental plans and never forces the structural creativity of a moonshot.
Fearing the uncomfortable lane
Choosing only safe bets forfeits both the big outcomes and the valuable lessons that ambitious failures provide.
Is it for you?
Best for
Founders and leaders setting ambitious, structurally creative goals or philanthropic commitments.
Not ideal for
Situations requiring conservative, risk-minimising targets with little tolerance for failure.
