The talk of Wall Street is worth more than ever.

Symphony, the bank-backed chat and IM service, said Monday it has recently closed a $100 million round of financing.

That’s on top of a recent $66 million financing round.

Investors in the latest round include Google, UBS, Société Générale and Silicon Valley venture capital firms, the company said.

The company has attracted a good deal of attention from Wall Street’s biggest players because the service could allow them to wean themselves from Bloomberg’s $24,000-a-year terminal, on whose chat and instant-messaging services traders rely to trade stocks and bonds.

The total number of backers in the Palo Alto, Calif.-based Symphony now stands at 21, including original backers Goldman Sachs and JPMorgan Chase — as well as new tech investors like Merus Capital and Lakestar.

“This financing is a vote of confidence in Symphony’s value proposition and benefits to business users,” David Gurle, founder and CEO of Symphony, said in a statement.
Symphony’s funding round comes a month after the company, as well as four banks, agreed to beef up its paper trail so regulators can keep tabs on bankers without tipping them off.
