Sensage

Sensage, Inc. was an American enterprise software company specializing in security information and event management (SIEM) and event data warehousing, founded in 2000 by Adam Sah (originally as Addamark Technologies Inc., rebranded to Sensage in 2004). Headquartered in Redwood City, California, Sensage developed a columnar database architecture optimized for high-volume security event data, using massively parallel processing (MPP) to handle petabyte-scale log data for cybersecurity, compliance, and fraud analytics. Its flagship product, the Sensage Event Data Warehouse (EDW), enabled real-time querying, forensic investigation, and regulatory reporting without traditional indexing. Sensage raised approximately $47 million in total funding from investors including Sierra Ventures, Canaan Partners, FTV Capital, and Mitsui & Co. Venture Partners. In October 2012, KEYW Corporation acquired Sensage for approximately $24-34.5 million.
