Pricing
top-down VS bottom-up
Top-Down
What currently exists?
How much are they selling for?
How does my product compare?
Cost of goods is not as much as a factor.
Bottom-Up
How much does my product cost to build?
What would be a good/fair price to sell it for?
How much do I need to make for it to be "worth it" to me?
Caution!

"Speaking of customer support, isn't that a total nightmare?"
Not really!
Focus on the customer experience:
- under-promise, over-deliver
- under-promise, over-deliver
- under-promise, over-deliver
- focus on being a human
- deliver things that "just work"
- give people the benefit of the doubt
- under-promise, over-deliver
