What you really want to see is a reputable VC (preferably from Sand Hill Road) backing the company. That might be coming in the future, but for now we are doing well without VCs.
Gosh, this is a very bad sign of arguing wiht potentail customers who simply give good advice on telling a little about who is behind the company (like address, etc). Why do you want to hide such info?
I am a founder myself and I haven't put founders' info on our website for a simple reason... one of the cofounders has not yet quit his day job and he doesn't want his employers to know he is moonlighting.
A back story is even better.
This is a perfect example of the kind of page I'm talking about. https://www.cadcode.com/content/about-us
