Zero to Sold is a comprehensive and actionable guide through the four stages of a bootstrapped business: Preparation, Survival, Stability, and Growth. This is a book by me, Arvid Kahl. I am a software engineer turned entrepreneur turned writer. It’s a book about what I learned in over a decade, culminating in the successful sale of FeedbackPanda, an EdTech Software-as-a-Service business that I founded with my partner Danielle Simpson.
