Marc Krejci will make validation your superpower in the AI era
Marc Krejci is the founder of Pathfinder Foundry. After 7.5 years leading product at Meta and decades working with hundreds of founders in Silicon Valley, he kept seeing the same mistake: people believing instead of testing.
AI has made building nearly free, but not knowing what's worth building. Marc teaches ProtoVibing and customer discovery as a skill, not a personality trait, turning guessing into evidence before founders bet their runway.

Product-Market Fit Without Guessing
I can't say enough about this course and how Marc's structured approach saved me hundreds of hours I would have wasted building something that wasn't useful. The tips/tricks and tools Marc shared are priceless - not only in their application but his expert guidance in using the right tool in the right way for a given outcome - I would not have figured it out myself, and now I can confidently build whatever I dream!
