Notes from building a startup, shared openly
Hi HN, I started a small newsletter to document what I’m learning while building projects — the decisions, mistakes, and experiments that usually stay behind the scenes. It’s not a growth hack or a polished media thing. Just short write-ups about what worked, what didn’t, and how I’m thinking through problems as I go. I’ve only published a couple of posts so far, but it’s grown to 1,000+ readers, which surprised me. Sharing here in case it’s useful to others who enjoy building in public or learning from real-world attempts rather than theory. Happy to hear feedback or ideas on what would be…
In plain words
Notes from building a startup is a newsletter documenting the real experiences of someone building projects, including decisions, mistakes, and experiments. It is for people interested in learning from practical attempts rather than theory, particularly those who value building in public. The newsletter shares short write-ups about what worked and what didn't, offering behind-the-scenes insights into problem-solving that typically remain hidden during startup development.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
