Cloud services provider J2 Global of Hollywood continued its acquisition binge into the first quarter of this year, buying six small companies for an undisclosed total.

Those acquisitions included British call management company Callstream; email marketing company Mailout Interactive Inc. of Edmonton, Canada; online data backup company VaultLogix of Danvers, Mass.; online data backup company Yotta280 Inc. of Jacksonville, Fla.; as well as assets owned by Global Data Vault of Dallas and Backup Solutions of Orange.

J2 Global has rolled up more than 126 small companies since its founding in 1996. Chief Executive Hemi Zucker explained to the Business Journal in a February interview that rolling up competitors has become a cost-efficient way to acquire new customers.

Last year, J2 Global acquired 24 companies and paid between $12 million to $14 million apiece on average. J2 has funded its acquisition streak by issuing $599 million in bonds and convertible debt since 2012.

J2 Global did not disclose acquisition terms or amounts, citing an immaterial financial impact on the company. The company’s share price fell 44 cents on Monday to close at $61 on the Nasdaq.
