Kalzumeus Software
My name is Patrick McKenzie (better known as patio11 on the Internets). Once upon a time, I was an engineer. I had an idea for some software. Programming it was pretty easy. Marketing it was not, but I really enjoyed the new challenge. At some point over the years, I graduated from being an engineer to running a software business. I’ve been writing regularly since 2006 — check out my greatest hits for a curated list of the best stuff I’ve produced, or read this if you want the brief overview.
Kalzumeus Software is named after a dragon in a long-forgotten RPG campaign. It’s so hard to find available .com domain names these days, I swear.
I love talking to other small businesses at any time, for any reason: please, drop me an email. I respond to as many as I can, time permitting. Nothing makes me happier than helping people out. See the Standing Invitation for details.
These days I’m working at Stripe on Stripe Atlas. Opinions expressed on this site are my own.
Some Things I've Done

This is outside of my normal software-focused beat, but I met some folks who were very interested in public policy recently. I found, to my surprise, that I probably understand one innovative Japanese tax policy better than very well-informed people who geek out about tax policy [0].

This is outside my usual brief, but one of my hobbies is that I used to ghostwrite letters to credit reporting agencies and banks. It is suddenly relevant after the Equifax breach, so I’m writing down what I know to help folks who might need this in the future.
Jonathan Siegel is a buddy of mine who lives in Tokyo. I can’t decide whether I’m more floored by the fact that he runs five businesses at once or has eight kids. He recently wrote a book The San Francisco Fallacy, mostly to share his experience with running software businesses for the last two decades with folks who might be getting a wee bit too much of their advice from Techcrunch.
