Traction Thinking Prototype Cohort — Test your idea with real customers in 30 days.

74% of all startups fail because founders build and scale before they’re ready. Less than 5% fail due to the competition. Founders spend time building the thing right before figuring out if it’s the right thing to build. The result? Crickets.

But there’s another option: rapid prototyping.

During this 30-day cohort program, you will develop this secret superpower that can quite literally turn the odds in your favour. You’ll gather online with a group of like-minded entrepreneurs to learn how to build products and services that make customers say “wow!” — by actually doing it.

# Prototypes


The Traction Thinking Cohort is a 30-day rapid prototyping bootcamp with real-time and asynchronous support that teaches you how to test ideas with real customers — by doing it.

Don’t waste your time building something no one wants.

Everyone knows 95% of all startups fail, but most people don’t know that startups are rarely killed by the marketplace. They commit suicide due to founder mistakes.

And 74% of those mistakes are this: building or scaling a product too soon.

They have an idea and they want to get it in front of customers, so they start building it. But it’s too soon, and the startup crashes under the weight of its own assumptions.

There’s another option…

Rapid Prototyping:

  • Build a “facade” of the real thing.
  • Show it to real customers.
  • Look for a “wow moment”.
  • Iterate.

No failed product builds. No money flushed down the toilet. No wasted time.

Just a product that customers are _begging you_ to build.

Hello rapid prototyping.

Goodbye unwanted products.

Some kind words from recent cohorts…

We’ve been running cohort programs for entrepreneurs in the Sacramento region (and beyond) for years. Check out what some of our recent participants have had to say about the experience.


Thanks to our sponsors for making this program possible.

Due to the generous sponsorship of the Sacramento MetroBusiness Center, as well as the support of these organizations, the Fall 2022 cohort is completely free for all participants.

Sacramento MetroBusinessCenterThe Right Box


Hey — I’m JDM 👋And I’ll be your facilitator.

I’m JDM, aka Josh David Miller, an entrepreneur and startup advisor based in Sacramento, CA. I’m the founder of The Right Box, where we use design thinking to help venture-backed startups find product-market fit.

Over the past decade, I helped startup founders and innovators l aunch or grow 100+ products. Those founders call me “the shredder of business models”.

I think that’s probably a compliment, but I choose not to validate that.

I fashion myself an instigator on something of a quixotic quest to fix entrepreneurship by challenging how we think about our craft. And you can expect me to challenge you during this cohort.

Or, as one founder recently put it: “Josh makes it easy to get rejected and built up at the same time.”
