Having used the canvas for several years, and now working directly with Alex Osterwalder, I've met a lot of people who have developed new techniques with it. Some of them have been instrumental in spotting killer assumptions, so I'd like to share those with you. Broadly, I'll tell you about finding critical points in your business model assumptions, choosing a growth engine, validating your business model with real and hypothetical numbers, and if there's time, prototyping widely to spot better hypotheses and record better customer input. I imagine this will be a fast and broad overview, so if there's any area in particular you're interested in, please let me know here so I can plan to drill into it instead.
