001 – About
Building products at the
intersection of technology
and growth.
Pelle Krukow is a 22-year-old self-taught software engineer and entrepreneur based in Hamburg, Germany. I've been writing code since I was 15 and building businesses since I was 16.
What started as curiosity, rooting phones, modding games and tinkering with systems, turned into a career building products used by millions.
Today I build Meridian, which turns payment data into finished DATEV bookkeeping for German businesses, and Frozen Tweaks, performance software for competitive PC gamers. Before that I founded FrostChanger, a game customization platform used by millions of players, which was sold in 2025.

Founder & CEO (Acquired)
Game customization software for PC. Built from scratch at 16 and grown into a platform used by millions of players across CS2, Valorant and more, with its own launcher, backend infrastructure, support team and payment processing. Started on C# and moved to C++ as the client grew. Sold in 2025.
003 – Journey
A decade of building
First Steps
Started making YouTube videos as a kid, real-life content and Minecraft videos. The spark that lit the fire.
The Tinkerer
Rooted my first Android phone at 11. Jailbroke iPhones. Driven by the urge to understand how systems work.
FrostChanger is Born
A friend mentioned custom skins in Fortnite. That conversation turned into a game modification platform built from scratch at 16.
Scaling Up
FrostChanger hit critical mass. Expanded to CS2, Valorant, and more. Growing a community, shipping code daily.
Full-Time
Graduated and went all in. Rebuilt the platform on React and Next.js, hired support, took payments in-house.
Deep Technical Work
Dove deep into C++ and systems programming. Built advanced tools, started exploring AI and automation. Passed 100,000 subscribers on YouTube.
New Chapter
Sold FrostChanger. Launched Frozen Tweaks, taking everything learned about Windows internals into a performance product for competitive players.
Building the Future
Building Meridian, DATEV automation for payment data, after spending one too many months reconciling my own books by hand.
