How Josef acquired customers
Tools used to build Setter AI
Josef taught himself to code at age 13. He freelanced until he saved enough runway to commit to entrepreneurship.
His first product failed and runway was running dry. Out of desperation, he tried the 12-startups-in-12-months challenge.
Three months in, he found the right product - Setter AI. A little over a year later, he hit $10K MRR.
When desperate, constraints like 12x12 force you to validate faster
Choose speed to market over technical perfectionism
Building a business is messier than building software - embrace it
Target non-technical users when possible - larger market, less competition
