So here's a question, what's the lifespan on this thing? I mean the concept is great. And there's always going to be start ups in IT that need money, but is Leancy ever going to get so big that more investments won't be needed? What happens then?
There are no startups
Just like Charles Ponzi never purchased any international reply coupons, they do not invest in any startups.
