Love short tidbits like this. Imagine a seed getting heaps of water and an absolute blasting of light before ever hitting the soil. That's my metaphor for a company focusing on growth goals out of the gate. Pointless.
Sam frames PMF as when someone "spontaneously tells other people to use" your product.
1) Do you agree? Have you seen that happen with your product yet? If not, why not?
The underlying fact here is that you begin, middle and end with customer experience.
2) How many customers (or potential customers) have you actually spoken with this week? Any memorable moments?
