Seen In & Worked With

Sound familiar?

You do great work. You're the person everyone comes to for help. But louder colleagues keep getting promoted ahead of you.

You know you're supposed to "play the game", but it feels like becoming someone you're not.

That's why I built The Quiet Power Playbook.


Here's how it works

First 7 Days

The Foundation

7 daily emails to help you speak up without guilt, handle difficult colleagues without the spiral, and advocate for yourself without feeling "difficult".

Every Sunday

The Playbook

One research-backed strategy you can use immediately. Plus an AI prompt to apply it to your own situation.

Every Wednesday

The Perspective

A 3-minute reframe to shift how you see a stuck situation. Short enough to read over coffee, so clear you know what to do next.


I'm Martin Schweinsberg: professor at ESMT Berlin, psychologist, and I'm naturally more comfortable in the library than in the boardroom.

Every framework comes from peer-reviewed research, proven by Kind and Quiet leaders who got promoted without becoming someone else.
