Lean pitching involves applying Lean Startup and customer development principles to reduce waste in pitches. Pre-pitch research includes reviewing social media, past investments, blogs, and determining if the pitch will be to an individual or group. The business model canvas helps structure the pitch. Key questions identify the most important factors for investors. An effective pitch is short, simple, and memorable, focusing on what, how, and why. High concept pitches use familiar concepts to quickly convey the idea. Post-pitch reflection identifies surprises, lessons learned, directions to test, and risks. Resources for improving pitching skills are provided.
