First online products
Programming from age thirteen and launching the first multimedia websites.
Mikołaj Lehman / 20+ years in digital products
I build companies, teams and digital products.
I started programming at thirteen. Since then, I have launched internet products, built technology companies and helped turn uncertain ideas into products people genuinely use.
Biography
It started with curiosity.
I created my first websites in 2002-2003. They began as multimedia portals and grew into internet radio, live club broadcasts and early social platforms.
Some projects disappeared. Others attracted users, integrated with popular services, and one was acquired. Each taught me that a valuable product is much more than well-written code.
Since 2009, I have been building GMI Software. I also co-created Hublock for logistics and Cognic, an AI assistant for therapists.
I am most useful before the code: when the problem must be clarified, risk made explicit and the smallest credible test selected. That is where most product value is created or lost.
