Intercom's story has been a wonderful one to watch. They're a particular inspiration for those of us in Ireland; they've consistently aimed high, have set high standards for themselves, and generally raised the bar for Irish companies.
Their blogging has been interesting since before Intercom was even incorporated (at their consultancy company, Contrast's[1], blog).
They're also a bunch of smart, down to earth people.
Exceptional folks. Congratulations.
