I could probably write a book on this. I've been pitched a few hundred times, invested as an angel ~50+ times, and raised twice (so far.)

If your product speaks for itself, none of the advice here matters. You'll get multiple offers to play off each other.

A great lawyer will help you navigate this. I can recommend several if needed.

Try to pitch the weaker fit and less interesting VCs first. This will let you get your patter down, make the strange questions unsurprising, etc.
