The Pith OS is an AI pitch system that helps early-stage startup founders create better pitches. It's like having a shark that listens to your pitch and gives you advice on how to improve it. It points out parts that might be confusing or not engaging enough and suggests how to make them clearer or more interesting. The tool also includes short, easy-to-understand videos that teach you about strategy, marketing and storytelling. You can also share your pitches with other founders, get their opinions, and see how they do it.
