So true about needing a solid revenue model. VCs want to see that you know how to make money, not just spend it. If your model's not working on a small scale, throwing VC money at it won't magically fix it. Scale what works, ditch what doesn't.

Great overview. On scalability, it's crucial that startups don't just think big but have a clear path to getting there. You have a platform? Great. How does it grow? Network effects? Virality? Cold sales? What's the CAC? How does LTV look as you scale? Angels will grill you on these.
