how anyone can identify it is a revolutionary idea at it's initial stage .
Simply by doing an indepth research of the services offered by the start up. Everything can be seen on the whitepaper but having it doesn't mean the projetc can be deliver. So I is always best to reasearch and dig more information on the capability of the project team.
today also some people with big unique idea trying to make a revolutionary product at any corner of world how we can find these peoples
they also discuss about idea and working together like satoshi
You can't find them if they do not present themselves. Start up needs developer and team, they will present themselves via their whitepaper and portfolio. From that we just need to dig deeper to verify the developers' credentials.
