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 .

Recent Content

I write two weekly newsletters, co-host a podcast, and create content on LinkedIn, YouTube, Instagram and other places — all based around helping first-time founders launch sooner and scale faster with traction science.

These are four of my most recent pieces:

  Start Pseudoscience Series #1. Your idea feels safest before customers touch it. The real work is shortening time to customer, falsifying the fantasy, and learning to bounce when reality hits.

• 🧠 High Conviction Founder Series: They fall in love with the customer's problem, not their own solution

  Habit #2: fall in love with the customer's problem, not your own idea of it. Your solution is a guess. Your problem statement is a guess too, just an earlier one.

• Building got faster. Validation didn't.

  AI compressed your build cycle, but not your validation cycle. You can ship in a day, but customers still decide on their own timeline. Here's where "AI native" founders keep getting it wrong.

• 🧠 High Conviction Founder Series: They test what could kill them

  Your logo can't reject you. Your wireframes will never say no. Your customers will. Habit #1 of high conviction founders: test what could kill you first.
