Good points except for the last one about keeping shut. Being tight lipped and paranoid is not how winners operate. Share your success and lessons. Be open.
Thank you- great feedback! I've found that being quiet about your successes gives you a longer runway to build a moat that makes it more difficult to compete with you
My belief in startups is that the only IP is execution. Ideas are cheap.
When running a business you are making hundreds of decisions a month (maybe thousands). Unless they know and can make the same ones roughly, they can't replicate your success.
Do you have an example of how not being quiet hurt your/someone else's moat?
