About

I'm Eric Martinez. I've worked on flywheels at three startups, from a lab demo that closed a contract to a unit that ran for months at Camp Pendleton.

Now I study how hard tech companies get their first machine built, funded and running, and write it down for the founders building the next ones.

The Hard Tech Startup Playbook

A step-by-step guide from first design to first commercial unit, drawn from the companies that made it. In progress. Newsletter readers hear first.
