The Product Development Academy

Bring your product idea to life and make your first sale.

You don't need to be an engineer or understand how any of it works yet. I'll walk you through the whole journey, from prototyping and manufacturing to patents, marketing, and your first sale, the same way I built companies that sold 2.2M+ products worldwide.

Why we exist

Most great products never get made. Not because the idea was wrong, but because the path from idea to shelf is hidden behind closed factory doors. We exist to open them.

For decades, knowing how to take a product from sketch to manufacturing was reserved for insiders: engineers, agencies, and factories that speak a language outsiders never learn.

We believe the next generation of physical products will come from independent inventors and founders. So we built the curriculum, the templates, and the network to make that possible, without a single closed door.

This isn't a course about products. It's an institution for the people who make them.

A modern manufacturing floor with CNC machines and assembly lines

We teach how products are actually made: tooling, suppliers, tolerances, and cost. Not a theory of how they might be.

The process

Six stages. One product. Start to shelf.

Concept & sketch
01 / 06

Concept & sketch

Translate a rough idea into a defined, drawable concept with the right constraints and intent.

CAD & engineering
02 / 06

CAD & engineering

Develop precise 3D models engineered for how the product will actually be made.

Prototype
03 / 06

Prototype

Hold a real, working prototype. Test, refine, and prove the design in your hands.

Manufacturing
04 / 06

Manufacturing

Source vetted suppliers, design for manufacturing, and move to production-ready tooling.

Packaging
05 / 06

Packaging

Build a brand and retail-ready packaging system that makes the product feel inevitable.

Launch
06 / 06

Launch

Take the finished product to market and turn it into a real, repeatable business.

The path every product takes

What the path from idea to product looks like.

Every physical product follows the same path from idea to shelf. Here it is stage by stage: concept, engineering, prototype, manufacturing, and market. It's the exact path the course walks you through.

01

Validate

Start from a rough idea or sketch and pressure-test whether it's worth building before you spend a dollar.

02

Design & engineer

Refine the concept into CAD, engineered for how it'll actually be made, and prove it through prototype rounds.

03

Manufacture

Compare vetted suppliers, commission tooling, and plan a first production run that hits your target cost.

04

Launch

Package it retail-ready and take it to market with a direct-to-consumer launch plan.

Meet your instructor

Hi, I'm Mark. I started with just an idea, too.

I started out as a CNC machinist with a big dream and no roadmap. At 22, I built a small manufacturing shop inside my studio apartment and launched my first company. Within two years it was 17 employees and millions in sales, and it grew to 37 people and 2.2M+ products sold worldwide. Along the way I gave a TED talk, sold inventions to General Mills' organoleptics division, and made it into the New York Times.

From there I founded and scaled more manufacturing companies, including a truck camper company that sold over 615 units. Across those businesses I employed nearly 70 people at our peak and earned more than 14 patents, many of them my own. I also invested in the business side of building companies, studying at MIT Sloan and graduating from Harvard Business School.

Here's what I care about most, though: I've spent my career turning raw ideas into real products, and I've sold millions of them to people around the world. Now I want to hand you the exact playbook, from the idea in your head, to a product in your hands, into the hands of people everywhere.
