Big Five scan . how you lead

The map of who you are
as a leader.

You are building a company. You make decisions every day. But do you actually know who you are as a leader? Not a label. The real thing: what drives you, what drains you, and where your untapped potential is hiding. The Big Five scan gives you the map.

15 minutes. 5 euros.

01 . The problem

You lead on instinct.
But instinct has a name.

Most founders build on talent and gut feel. It works. But somewhere in the growth, you start running into patterns you cannot explain. Why do certain conversations drain you? Why do some team members or clients light you up while others leave you flat? Why do you decide fast one day and endlessly stall the next?

The answer is not a new system or a new coach. It is who you are. And that can be measured. Scientifically, precisely, without any fluff.

02 . What you get

A rich, science-backed map of who you are.

The Big Five is the most researched personality model in the world. No labels, no boxes. Five dimensions, each with multiple facets, together forming an accurate picture of how you think, work, and lead.

O

Openness

Ideas, vision, creativity

How curious are you? How do you handle uncertainty and new ideas? This dimension tells you how you innovate and where you get stuck when the world moves too fast or too slow.

C

Conscientiousness

Discipline, focus, follow-through

The engine behind execution. High scores here build big things. Low scores are not a weakness but a signal for where you need support or how to use your team around you.

E

Extraversion

Energy, people, presence

Not introvert or extravert as a label. Where do you recharge? How do you own a room? How do you show up as a leader? And what costs you energy in interactions?

A

Agreeableness

Collaboration, trust, honesty

How do you handle conflict, collaboration, and extending trust? Founders with lower agreeableness build fast but hit friction. Higher agreeableness brings buy-in, sometimes at the cost of speed.

N

Neuroticism

Stability, stress, emotional reactivity

How steady are you under pressure? This is the most underrated of the five. Low scores mean calm under fire. High scores mean sensitivity, but also depth and self-awareness.

Plus: more than just your score.

  • Facets per trait: 6 sub-dimensions per Big Five factor, not just the headline number.
  • Leadership insights: how your profile plays out when you are building, deciding, and managing people.
  • Blind spots: where you might be leaking energy or repeating patterns without noticing.
  • Strength map: what you naturally do well and how to use it as a founder.
