The build notes

The build notes

I've spent eleven years building software products for other people. Now I'm building and selling my own alongside the day job, and writing down every decision that costs real money or real time.

What's in it

  1. 01What I decided, and the two or three options I didn't take
  2. 02What it cost, in money and hours
  3. 03What the numbers actually did afterwards, including when they did nothing

Free. One click to leave.

What's not in it

Tool roundups, news, "10 things you should know", or anything I haven't done myself.

I don't send it on a fixed schedule. I send one when there's something worth sending.
