Proving just how volatile the ad-tech business is, Audience Science is shuttering less than a month after it lost longtime client Procter & Gamble.

The news, which Business Insider broke Thursday night, reported that the ad-tech firm had nine offices in multiple countries, including the U.S., the U.K., China, and Brazil.

The company’s CEO Bill Gossman confirmed that Audience Science has curtailed worldwide operations, AdExchanger reported.  The company has about 200 employees.

P&G ended its relationship with Audience Science for programmatic ad buying in March. The consumer package goods giant hired Neustar, which has a data management platform and a handful of demand-side platforms, to replace Audience Science.

P&G, which appears to have been the firm’s largest client, shifted its overall media business to Omnicom’s Hearts & Science less than a year ago.
