I have seen nearly 10 pitches during this start-up hackthon and most of they are still thinking about vertical marketplace or o2o platforms such as platform to find friends, babysitters or pets.
No offense to Icelanders or European friends. But small vertical just can't become a sustainable internet business. E-commerce and O2O (online to offline) always need to be a "platform of everything" to become profitable and substainable.
It's very difficult to operate a vertical platform unless you can reduce the cost dramatically.
What Iceland or small countries need is a good generic O2O platform for most things. This platform will be generic yet flexible enough so that each vertical can be operated on top of it without creating seprate software.
Nostr to the rescue. Vertical business can hugely benifit from Nostr because they don't have to create standalone software and buy in all sorts of cost of building a software. They can just use Nostr to commerce and win.
I will start an Iceland Nostr Meetup.
