News: The firm launched its first product, Symphony’s Secure Messaging application, in mid September.
Cloud-based communications start-up Symphony has secured over $100m in capital from a group of new investors, including the tech giant Google.
The funding, which is aimed at speed global customer adoption, is also supported by Lakestar, Natixis, Societe Generale and UBS along with a group of existing investors, including Silicon Valley venture firm Merus Capital.
Symphony was established only last year and had raised $66m in the initial funding round from 15 major financial institutions.
Earlier in the month, The Wall Street Journal had indicated that new investments will raise the value of the company to $650m.
Symphony founder and CEO David Gurle said: "This financing is a vote of confidence in Symphony’s value proposition and benefits to business users.
"We are making a major leap toward a safer and more productive method of communication for individuals, teams and businesses."
On 15 September, Symphony has launched its first product Secure Messaging application.
Google is the first strategic investor for the start-up outside of the financial industry, reports Re/code.
Symphony looked forward to raise up to $50m initially through the financing, but was prompted to double the original plan due to rising investor demands.
