Founders have a different sort of information. They have the information that comes from working in, living in the sector 24/7 for years. They know about achievable revenues and margins, they know competitors’ products and strategies, they know which people at other companies are most valuable, they know about companies just starting that have valuable and useful products, etc. They hear from their salespeople, who hear from their clients what other companies’ salespeople are saying about their competitors. They know more about their industry than anyone. They are happy to share this information with you, if you are helping them.
