Where to Start? (On a piece of paper)

Chief Revenue Officer of StackCommerce and Former CEO and Founder of FanBread (acquired)

When Karl and I first discussed the idea that would become FanBread, a company Karl built and later sold, he scribbled it down on a napkin no larger than 3x3 inches.

That tiny idea became a prototype, then an incorporated company, then a fundraising round, then a team of incredibly talented people, then a product that made headlines and promoted celebrities, then finally an exit worth millions.

How did Karl learn to do all of that? How did I learn to do it? Trial and error.

We didn’t wake up knowing how to fundraise, build an MVP, or hire the right people, we just guessed. And when our guesses were right, we won, but when they were wrong, we lost money, time, and so much more.

“When I hired our first and only senior backend developer, he seemed like a shy guy that I supposed would one day ‘warm up’ to the team.

That day never came.

Not only did he keep quiet, he came in late, never voiced his opinion, and regularly made up excuses for his poor performance.

Without a proper way to motivate him, I considered letting him go. That’s where I hit an even larger snag: being our only senior developer, he alone had the knowledge to access our infrastructure.

If I fired him, he may have retaliated by sabotaging our development process or worse, completely nuking the product.

I ended up sticking it out with him and scrambling to hire another dev, but learned that entrepreneurs cannot afford to consolidate knowledge in a single person.

And as cruel as it sounds, leaders must be able to lock down everything at a moment’s notice to prevent disgruntled employees from taking rash actions.

By doing so, we’re not just safeguarding our own contributions, but the contributions of every team member that worked their ass off to make the product come together."

“Sounds Like Bullsh*t…”

We don’t have microphones hidden in your room, but we can actually hear your eyes rolling. Don’t ask how, it’s wizard-stuff.

And we understand why: if we’re so good at building these companies and selling them for mega-profits, why make this course? Why help you eat our lunch?

There’s a big difference between knowing what to do, and actually doing it. Every step in this course is easy to learn, difficult to master, and hard af to actually do.

We want to greet and help the people that put their money where their mouths are. Those people will build the companies of the future. They are the same people that might one day be our business partners. They are people like you.

ME2.0 Founder and Brand Manager at Unilever

From Napkin Sketch to Multi-Million Dollar Exit has been a great resource for me as the founder of an early stage start up.

Having direct access to Ben and Karl is a true differentiator of this course. Both Ben and Karl have been more than willing to answer questions and provide additional resources where needed.

My experience with Rootstrap has been transformative.

Every step of the way, from napkin sketch to our current platform, they have showered us with value.
