Others in the group included existing investor Open Ocean, Truecaller Chairman Stefan Lennhammer, and a private investor who is known for his high profile Silicon Valley investments, Truecaller said in a statement.
The company had received funding of USD 1.3 million in September 2012 by Open Ocean, an investor in European software start-ups with large user bases or communities.
Truecaller, which has over 45 million users, including in India, helps phone users identify callers and block spam calls.
The company is also integrating Yelp API data as part of its new product launch on Android and iOS, which allows users to identify reviewed businesses globally. It also incorporates social features to make it easier for users to update contacts and get in touch with people they may know.

"This integration takes Truecaller's own search engine to find people and identify numbers, and combines it with Yelp's crowdsourced business ratings to create one place for genuine and accurate information for the world to use," the statement said.
The ability for users to take advantage of Yelp's local listings follows on a major partnership that Truecaller forged with Twitter to allow users to tweet and follow other users directly through the Truecaller app.
"2013 was an amazing year for Truecaller and our latest partnership with Yelp expands the value of our service to millions of new users," Truecaller co-founder and CEO Alan Mamedi said.
