The company originally started out offering budget group tours to destinations that required you to be in a tour group i.e. North Korea, Turkmenistan, Chernobyl, Iran for some passports as well as low cost bespoke Trans-Mongolian trips. Very much targeted at people that would travel independently, except for the destinations where that would not be possible.
It's expanded massively over time to include anywhere with a tricky visa (Libya, Saudi..), break-away regions (South-Ossetia, Somaliland), places with varying security situations (Afghanistan), or making expensive places more affordable to visit than other companies (Chad).
On top of being a partner I manage all our tours to North Korea, the North and South Caucasus, some in East Africa and also our "Remote one-offs" to places like Oymyakon and Pitcairn Island. On top of this I have the pleasure of leading 5 to 6 of our group tours a year.
