Hi, I'm Jakob

I'm passionate about bootstrap entrepreneurship and recently decided to pursue a Bootstrap MBA.

My goal is to learn everything I can about product ideation, marketing, and product development by building and launching a new product each month. If you're interested in following along, join my weekly newsletter.
