Pitch Masters helps startups perfect their pitches to investors, partners, and customers, similar to how Toastmasters helps with public speaking. This week's mission challenges participants to describe their business in a Twitter-length post using a specific format: who they are, how to quickly identify and categorize them, who they help, and how they benefit their audience. The document provides examples from Power Portal and encourages participants to create their own 3 short pitches within 5-7 minutes each for a vote.
