🔍 Key Takeaways (No Spoilers)
This round surfaced a different tension: venture-scale vs. lifestyle/business clarity.
Not every great business is a venture business: Investors care deeply about exit paths, and not every founder does.
Founder clarity matters (even if it’s uncomfortable): Being upfront about goals can help, or hurt, depending on the audience.
Scrappiness is a signal but not the whole story: Hustle gets attention, but investors still look for scalable systems.
Consumer is hard but in different ways: Hardware vs. platform plays bring completely different risks and expectations
Market size ≠ business model clarity: Big markets are attractive, but how you capture value matters more.
