Overview
Condusiv Technologies is a privately held American software company headquartered in Burbank, California. Its roots extend to Executive Software International, a company founded by Craig Jensen in 1981 to develop system software for Digital Equipment Corporation VAX/VMS environments. The business became closely associated with Diskeeper, a disk-defragmentation product designed to optimize file-system performance without requiring systems to be taken offline. That capability initially attracted organizations operating mission-critical computing environments, including large corporations, government agencies, air-traffic-control operations, and other customers that needed systems to remain available continuously. During the late 1980s and early 1990s, the company established a strong position in the market for third-party software supporting Digital Equipment Corporation business computers. It was included on Software magazine’s ranking of leading independent software companies for four consecutive years from 1989 through 1992. The company later expanded into Microsoft Windows. In 1995, Microsoft asked the business to develop software for Windows NT before the operating system’s public release. The resulting work helped bring Diskeeper into the Windows market, where disk defragmentation became the company’s best-known category. The business subsequently operated under the Diskeeper Corporation name, reflecting the importance of its flagship product. Its portfolio broadened beyond conventional defragmentation to include Undelete, a utility for recovering accidentally deleted files; V-locity Virtual Machine, designed to improve disk performance in virtual-server environments; and technologies addressing solid-state storage, boot performance, background processing, and write optimization. HyperFast was positioned as an optimizer for solid-state drives, HyperBoot addressed system startup performance, and InvisiTasking was intended to let optimization work run in the background with limited visibility to users. IntelliWrite, introduced in 2009, used a file-system driver approach intended to reduce fragmentation at the time data was written rather than relying only on later defragmentation. Condusiv also developed and licensed technology for original-equipment manufacturers. ExpressCache, for example, uses a smaller solid-state drive as a cache for a larger hard disk, with the goal of improving boot and application-launch times. The company’s OEM relationships have included SanDisk, Samsung, and LG, giving its technologies a route into consumer and enterprise hardware products in addition to direct software sales and support. Jerry Baldwin became chief executive officer in September 2011, taking over managerial and day-to-day responsibilities from Jensen. Under Baldwin, the company adopted the Condusiv Technologies name and repositioned itself around cloud computing, virtualization, and performance optimization. The “Think Faster” tagline expressed this strategic emphasis. Condusiv’s public profile therefore reflects a transition from a specialist defragmentation vendor into a broader storage- and infrastructure-performance software provider. Publicly available reference material provides limited information about its current leadership, ownership, financial performance, and present product availability.
History
Condusiv Technologies traces its origins to Executive Software International, founded by Craig Jensen in March 1981. Jensen had studied electrical engineering at Northwestern University and gained early computing experience through work as a computer operator. Before founding the company, he worked on operating systems at Applied Data Research and later at Data General Corporation. The company’s initial technical focus was the VAX/VMS platform, where it developed software that could defragment disks while systems remained online. This feature was particularly relevant to customers running continuous or mission-critical workloads. The company’s early customer base included Fortune 500 and Fortune 1000 corporations, public-sector agencies, air-traffic-control operations, and NASA-related environments. In the early 1990s, Diskeeper became the best-selling third-party software product for Digital Equipment Corporation business computers. Executive Software also appeared on Software magazine’s list of the top independent software companies from 1989 through 1992. A major expansion occurred in the mid-1990s. Microsoft asked the company to develop software for Windows NT before that operating system was released. As one of Microsoft’s original source-code licensees, Executive Software used this relationship to establish Diskeeper in the Windows market. The product became the central identity of the business, and the company later adopted the Diskeeper Corporation name. The portfolio expanded from defragmentation into a broader set of storage and performance tools. Undelete addressed recovery of files removed accidentally. V-locity Virtual Machine targeted disk optimization for virtualized servers. HyperFast focused on solid-state-drive optimization, while HyperBoot addressed startup performance. InvisiTasking was designed to run processes unobtrusively in the background. In 2009, the company introduced IntelliWrite, a file-system driver intended to take advantage of Windows’ file-write behavior so that data could be written in a less fragmented form from the outset. Condusiv also pursued OEM licensing. ExpressCache used a low-capacity solid-state drive to cache data for a larger hard disk, with the intended effect of improving boot and application-launch performance. Reference material identifies SanDisk, Samsung, and LG among the OEMs to which the company sold or licensed products and technologies. Jensen stepped down from the chief executive role in 2009, and Jerry Baldwin became CEO in September 2011. Baldwin assumed day-to-day managerial responsibility and renamed the organization Condusiv Technologies. The rebranding accompanied a restructuring and a stated shift toward cloud, virtualization, and optimization, summarized by the “Think Faster” motto. The company has also attracted controversy because of its connection to Scientology-related management practices. In 1991, Executive Software declined to renew support for Ciba-Geigy’s VAX version of Diskeeper after learning of Ciba-Geigy’s involvement in manufacturing Ritalin, while honoring the existing contractual term. In 2000, German authorities examined whether the inclusion of Diskeeper functionality in Windows 2000’s disk-defragmentation utility created a security concern, in a broader context involving German public-sector restrictions on dealings with Scientology members. Microsoft stated that it had tested the software and found no capability to collect or transmit user data. In 2008, two former employees sued over alleged dismissal connected to Hubbard Management training. The proposed injunction was removed in February 2009, and the case was dismissed in June of that year. A later arbitration involving the former employees’ attorney resulted in findings concerning confidential training documents and an award to Diskeeper for liquidated damages, attorney fees, and costs. Public reference material does not establish the company’s current ownership, financial scale, or the complete status of its product portfolio.
