The London-based remittances company raised the amount from Rakuten's FinTech Fund.
The raise follows Azimo's $20m Series B in June 2015 and its $10m Series A in March 2014.
It’s a strategic investment: the funding will be used to help Azimo integrate into messaging apps like Viber, but also to expand its services further into Asia from its primary base in Europe. The investment comes out of Rakuten’s FinTech Fund, which has been especially active recently, leading a $120 million round for Cabify and partnering with PayPal in a $30 million investment in investing app Acorns.
