All you need for the core deck is a 2X2 matrix.
You need to show how you're competing differently in the short-term and long-term.
When talking to investors, you need to address:
Why in the short-term, do you have a approach that's 10X better than alternatives?
What's the tradeoff? Along which dimension are you the best?
Why couldn't this company exist 10 years ago? (usually technological)
What network effects create long-term differentiation?
If someone copies your tech, why will you still win?
