"We were in stealth mode not for fear of competition but of finding out our idea wasn’t very good.

You’ve quit your job. Your friends and family are behind you. Everyone’s waiting for what brilliant thing you’ve come up with. I mean, you quit your job, so it must be a really good idea. But, the truth is you’re not so sure it’s that brilliant. Somedays you think it’s great. Somedays you think it’s doomed."

Lisa, you missed the most important line:

Unless you have an unbelievably good reason to be in “stealth mode” and it’s very unlikely you do, get out of it. You’re missing out, we did.

I agree 100%
