I have a few quite successful entrepreneur friends. While their products can be very different from mine (corepo.org), their advice is always welcomed :)
Honestly for people who'd be tempted of answering someone like Musk (as I've seen in interviews), I don't think taking advice from billionaires is a good idea, as you can't compare their situation with yours
@rubenwolff Jealous about the successful entrepreneur friends!
Good point. Another tricky thing about copying the giants like Musk is that their approaches have evolved a lot since their startup days. What he's done now might not have worked during his early days
