International money transfer innovator Azimo has locked in $20 million (£15 million) in new funding. The Series C investment was led by Rakuten Capital, and featured participation from a host of investors including e.ventures, Frog Capital, GR Capital Partners, Greycroft Partners, MCI, Quona Capital, and Silicon Valley Bank. The new funding takes Azimo’s total capital to $66 million.

Founder and CEO Michael Kent said the funding would help the company improve its platform and continue to grow its customer base. He added that Azimo would continue to focus on the European market, which he referred to as “the largest, most diverse and chronically underserved money transfer market in the world.”

Rakuten Capital managing partner Oskar Mielczarek de la Miel credited Azimo’s ability to keep customer acquisition costs low as one of the benefits of its partnership with the London-based fintech. “Customer acquisition costs have dropped by two-third since we first got involved with Azimo,” he said. “This latest funding will comfortably bring the business to sustained profitability within 12 months.”

Japan-based Rakuten Capital has been a consistent investor in fintech companies, including funding for other Finovate alums like CurrencyCloud, BlueVine, and Kreditech. Mielczarek de la Miel told The Financial Times that growth in the international digital money transfer industry has not only attracted investors, but also made firms like Azimo “very coveted assets,” that could be the target of acquirers.

Founded in 2012 and headquartered in London, U.K., Azimo demonstrated its international digital money transfer service at FinovateEurope 2013. The company offers safe and secure money transfers, verified by MasterCard and Visa, to more than 195 countries and in more than 60 different currencies. Azimo provides instant cash delivery to more than 50 countries, and most money transfers are processed in less than 24 hours. Azimo’s mobile app, available at Google Play and the Apple App Store, gives users instant updates and real-time currency alerts, as well.

With more than 1.5 million registered customers and more than $1 billion in annualized sending volume, Azimo has made significant additions and enhancements to its coverage in recent months. The company announced new, improved service to China in March and last December, Azimo revamped its service in Nigeria to bring faster transfers and broader cash delivery options. Also that month, Azimo launched its cash pick-up service in the Philippines.
