While I understand that ChromaOm can be profitable and even make its founders a tidy sum, I wonder why YC invested. In what way does this company have the potential to become huge? Colour schemes are always going to be a very narrow niche, and I can't quite see how this would turn into even a $10m company, let alone a $100m one... Then again if YC invested, pg and the rest of the panel must see something I'm not seeing...
