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.
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.
- You notice a pattern in how you react, but you cannot name it.
- You give others feedback you quietly need yourself but never admit.
- Your team reflects something back at you that you do not quite understand.
- You sense there is untapped potential in you, but you cannot put your finger on it.
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.
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.
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.
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?
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.
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.

Common questions.
Is this the same as Myers-Briggs or DISC?
No. Myers-Briggs and DISC are popular models but scientifically quite limited. The Big Five (IPIP-NEO) is the standard in academic psychology: validated, precise, and reproducible. You get a spectrum, not a box.
How long does the scan take?
About 15 minutes. The scan has 120 questions. That sounds like a lot but it moves fast. Most people finish in 12 to 18 minutes.
Is the scan in English?
Yes. Both the questions and the report are in English.
What do I do with the report?
Use it yourself to understand your patterns. Share it with a coach or mentor as a starting point. Go through it with your co-founder or team to improve how you work together. Or just use it as an honest mirror.
Why is it 5 euros and not 30?
This is an early access period. We are testing the quality of the report with a broad group of founders and coaches. The low price is the trade. When the price goes up, it will be because we know it is ready.
Can I forward or print the report?
Yes. You get a PDF you can download, print, and share. You also get a Claude / ChatGPT coaching pack to go deeper on your own.
