Product, Ambition, Leverage: How Y Combinator companies raise money

I am interested in hearing more from YC companies on how they balance the point about stacking meetings (10-20 per week) with being product focused. To me, these two objectives seem to be in conflict, and I don't understand how somebody can stay focused, and lean, while constantly chasing meetings.<p>What is the secret?

The first two (product &#38; ambition) make sense, but leverage is a different story.<p>While a low burn rate helps, a VC firm has more staying power over time than a startup.
