The injection comes from a mixture of private investors and a grant from Finnvera, a specialised financing company owned by the Finland government.
The company had previously secured an undisclosed seed round in March 2012 from TripIt co-founder Gregg Brockway as well as Vera Ventures, KoppiCatch and Finnish innovation agency TEKES.
Cabforce says the latest funding will be used to help push the service to more third party travel agencies and airlines.
