hey friends 👋
I’m JDM (aka Josh David Miller) and I’m a traction scientist — I partner with pre-seed and seed-stage startups to turn assumptions into data, and data into product-market fit, using science. I run design sprints at The Right Box , I’m co-founder of the Traction Lab incubator, and I’m a content creator.
Check out my recent content below, or read more about me .
Upcoming Events
Every week, I host live office hours to help early-stage founders cut through the noise and get real traction. It’s fast, practical, and occasionally a little spicy — and I’m often joined by smart friends who bring their own sharp takes to your startup questions.
