Ideas usually aren’t the problem.
Executing on an idea is though, and executing successfully on an idea is even harder.
As such it stands to reason that people with real business experience, connections and network are more likely to have success in executing an idea.
Chance of success is low. I think it was somewhere around 13% of startups that “make it” long enough to be deemed successful.
But it doesn’t mean they have better ideas, or as the headline suggests - “are more radical”.
