Hi Omar, interesting I asked the same thing a few days ago - the co-founders of Expanse tried working with the founder of Bitnation initially but they weren't on the same page, Bitnation had its own ideas and Expanse had theirs and no compromise was reached, so they each developed the their own version of borderless services.
The Expanse services promise to be of a high calibre so I'm told.
