Why would you come up "anonymously for now" ? If you have an already successful start-up experience, why not talking about it and tell us a bit about you ? What are the risks in doing so ?

I'm a bit cautious by nature and I'm just curious about it. If I had an already successful experience and were in your situation I'd rather talk about it and introduce myself a bit. It helps to gain trust from other people and would make your request more appealing.
