Nehemiah Security

Little is publicly known about Nehemiah Security as a distinct entity. The firm's website resolves to Dataminr, an AI-powered event, threat, and risk intelligence platform, indicating that Nehemiah Security's investment activities may be closely tied to Dataminr's operations. Dataminr's core product uses over 50 proprietary large language models to analyze 1 million public data sources in real time, serving enterprise, government, and industry clients. Dataminr's stated clients include more than 100 U.S. government agencies, 20+ international governments, and a majority of the Fortune 100. Its platform covers corporate security, cyber defense, employee safety, and supply chain risk. No separate investment portfolio or asset allocations have been disclosed for Nehemiah Security. The firm does not publicly disclose AUM, team size, founding year, or named principals. There is no record of additional offices outside Washington. No philanthropic or adjacent vehicles have been identified. A notable recent event: Dataminr announced its acquisition of ThreatConnect, though no date was provided on the site. Nehemiah Security's structural differentiator is its apparent integration with Dataminr — a rare example of a family office embedded within an operational AI security company. Without public filings or disclosures, the firm's governance, wealth origin, and investment strategy remain opaque.
