How long will the pre-ICO company go?

It ends today in 12 hours

How long has the pre-ICO campaign begun?

If I'm not mistaken, somewhere in early September

Have they already collected the necessary amount?

I think so, but I do not know for sure. I'm not familiar with the developments in person

And what about the demonstration platform? Do they already have the first build of the program or at least screenshots?

I think I saw something on their site, you can see there

Well, as far as I know the launch of the platform is planned after the ICO campaign.

When does the ICO campaign start and when will it end? Are there deadlines?

You can look at the site in the section "road map"
