Irvine-based Integrien, a developer of enterprise IT monitoring software, has been acquired by VMware, according to VMware this morning. Although VMware did not announce financial details of the acquisition, sources close to Integrien said the acquisition was worth $102M. The acquisition was a big win for Southern California's investors, particularly from Clearstone Venture Partners and the Tech Coast Angels. Integrien was venture backed by Clearstone Venture Partners, Acartha Group, Mariner Capital Ventures, and the Tech Coast Angels. Clearstone owned about half of the firm. The acquisition marks a string of successful exits for both Clearstone and the Tech Coast Angels, with Integrien marking the fifth exit over $100M for Clearstone in the last year. Clearstone's other major recent exits are Kazeon (acquired by EMC), Mimosa (Iron Mountain), Ankeena (Juniper Networks), and Meru Networks (IPO). The exit is also welcome news to the Tech Coast Angels, and is the third exit for the firm in as many months. The TCA recently saw the acquisition of Language Weaver, and IPOs in Green Dot and Trius Therapeutics. Integrien was founded by Al Eisaian and Mazda Marvasti, and is currently headed by Dale Quayle.
