Illustrated portrait of Piotr Kulpinski

I build software products and run them end to end.

I've been writing software for over 15 years, first in agencies and product teams. Now I work on my own from Kraków, mostly on directories and SaaS tools.

I like simple interfaces and short feedback loops. AI agents write much of my code now, so one person can run several products at once. I build in public and write about what I learn.

Now

Most of my time goes into Highseat, cookieless web analytics that ties revenue to the source that brought it.

I also run OpenAlternative, a directory of open source alternatives to proprietary software, and Dirstarter, the Next.js boilerplate behind a growing number of indie directories.
