- Problem: Without a problem to solve, you don’t have a product/service to offer.

- UVP: A value proposition is a promise of value to be delivered.
- Solution: Get out of the building. How do we know we’ve solved something?
- Channels: How doe s whom we wish to reach change with time & scale & customer segment?
- Unfair advantage: “The only real competitive advantage is that which cannot be copied and cannot be bought.” — Jason Cohen.
