John Cotter
I'm a zero to one builder: I turn raw ideas into working systems, from founder infrastructure to autonomy experiments, physical-product plays, and entrepreneurial ventures.
01 / Bio
Builder Profile. Testing ideas against reality.
My work sits where product sense, automation, research, and execution pressure meet. I like projects with real constraints, visible stakes, and enough weirdness to be worth chasing.
The through-line is simple: make the idea concrete, prove the signal, and keep tightening the loop until the system can carry its own weight.
- Background
- Founder-led software, AI-assisted workflows, product systems, and technical execution.
- Operating taste
- Clear proof, fast iteration, strong writing, and tools that earn their keep.
- After hours
- Side projects, practical experiments, and hobbies that tend to become new builds.
