How Launch Tomorrow compares to Lean Startup (according to chatGPT)

Out of curiosity, I asked chatGPT about how Launch Tomorrow compares to Lean Startup:

Overall, while both Launch Tomorrow and Lean Startup share similar principles and approaches, Launch Tomorrow places a greater emphasis on customer research and validation, and is designed to be a more streamlined and adaptable approach to product development.

To be honest, I am not sure I agree.

Launch Tomorrow build on Lean Startup's focus on customer discovery and development, focusing on the initial steps of using metrics to think quantitatively about opportunities.
