HubSpot’s Jeetu Mahtani (Man. Dir. Int’l), Brian Halligan (CEO), JD Sherman (COO), & Mark Roberge (SVP Sales) in the Dublin office

Back in September, HubSpot announced that it would be expanding to Europe by way of a Dublin office. Today, that office officially opens.

The company is already at 30 Dublin employees, and plans to bring that up to 150 over the next three years. Eight percent of HubSpot’s 8,600 customers are outside the U.S. and Canada, as illustrated in the map below:

Last month we reported on HubSpot’s 2012 numbers, including $52.5 million in revenue. When I spoke to CEO Brian Halligan for that story, he emphasized international expansion as a key priority for 2013.

Dublin’s about to get a healthy dose of orange.
