Karolina Sarna

Atmospheric physicist turned organizational diagnostician.
I build things, write things, and take things apart to see how they work.

Judged as a bird: broken.
In water: magnificent.

Context determines performance. I apply this at every scale — organizations, careers, daily practice.

PhD in atmospheric physics. Built €20M in climate adaptation products at ICEYE. Now I run Rebel Strategy Lab, build Codesea, write a book, and refuse to pick a lane.

Manifesto

Be a rounded human.

Code. Then close the laptop and bake bread. Read a scientific paper. Then read a fantasy novel. Then a graphic novel. Then a children's book, out loud, with voices.

Write. Write a terrible poem. Write a journal entry. Write a short story that goes nowhere. Write a letter to someone you'll never send it to. Play with words for the pure joy of watching them land differently than you expected.

Learn advanced maths just for fun. Not for your career. Not for a side project. For the pure satisfaction of your brain wrestling with something beautiful and useless.

Go to a museum. Stand in front of the classics until you feel something. Walk in the forest until you stop thinking about your inbox. Swim in a lake until your body reminds you it exists.

Cook a dinner from a cuisine you've never tried. Mess it up. Eat it anyway.

Dive deep into a tech field you know nothing about. Not to pivot. Not to 'stay competitive.' Because curiosity without a business case is the most underrated skill in tech.

Make cookies. Read the Stoics. Code some more.

The most fun to be around people in any room aren't the specialists. They're the ones who can hold a conversation about Marcus Aurelius AND distributed systems AND why sourdough needs a longer proof in cold weather.

Range isn't inefficiency. It's how you build pattern recognition that no single discipline can give you.

Be a whole human. The world gets better when you are.

Same thinking. Different scales.

The structural diagnosis that works on organizations works at every other scale too — markets, teams, individuals, daily practice. These are the other places I'm applying it.

Rebel Strategy Lab
Structural diagnosis for climate tech

Strategy consulting and organizational diagnosis for climate tech founders and investors. I diagnose what's structurally broken — not who to blame. Then redesign the system so the same people produce different outcomes.

Codesea
Code visualization for visual thinkers

AI writes code fast. Visual thinkers can't see what's being built. Codesea turns codebases into navigable visual maps — so you understand the architecture, not just that the tests pass.

How environment shapes who you become

We obsess over habits and mindset. We ignore the most powerful variable: the physical and social environment we inhabit. Room is about what the research actually says — and why designing your conditions matters more than managing your motivation.

Self-Leadership
The structural approach

The same method I use on organizations, applied to how you lead yourself. Not habits, not motivation. The environmental and structural conditions that are generating your current patterns — and how to change them.

04 — Writing

What I'm diagnosing.

On climate tech market structure, organizational failure, and the mechanisms most people have learned to work around instead of fix.

European electricity markets aren't broken. They're optimized for a grid that no longer exists.
The complexity paradox: brilliant technical founders build organizations that confuse everyone including themselves
The adaptation trap: when the workaround becomes the process and nobody remembers why
"Climate forward" means nothing. Here's what your company actually is.
Defense didn't steal climate tech companies. The absence of climate markets pushed them there.
