Siren secures strategic investment from Elastic

On December 2, Siren announced a strategic investment from Elastic, the company behind Elasticsearch. The investment deepens a decade-long partnership between the two companies and accelerates development of Siren’s AI-driven platform, including Siren’s newly launched K9 AI Companion, used by national security, law enforcement, and financial crime agencies worldwide.

The partnership combines the Elasticsearch Platform, which delivers real-time search, retrieval and anomaly detection across structured, unstructured, and streaming data, with Siren’s patented investigative intelligence technology, which fuses data from multiple sources into explainable, auditable insights. Through the partnership, the companies provide governments and organizations with an open, sovereign, and transparent alternative to closed proprietary systems. Additionally, the collaboration enables analysts to move seamlessly from signal detection to actionable insights, accelerating case resolution from days to hours and improving cross-agency collaboration.

National security and law enforcement agencies face increasingly sophisticated and blended threats such as cybercrime and terrorism, as well as human trafficking and on-the-ground warfare. The Siren-Elastic combination enables organizations to detect, connect, and act on intelligence faster and with greater clarity.

“This strategic investment reflects more than a decade of proven collaboration with Elastic,” said John Randles, CEO at Siren. “Together, we’re delivering unified intelligence, real-time search and deep investigation at a time when it’s never been more needed globally.”

“Our long-standing partnership with Siren demonstrates how blending search and AI technologies can provide national security and law enforcement with trusted, explainable solutions that help protect citizens and assets,” said Chris Townsend, global vice president, public sector at Elastic. “This investment underscores our commitment to building a trusted ecosystem of Search and AI partners addressing mission-critical use cases.”

At the core of Siren’s innovation is a unique and patented search and retrieval system built specifically for knowledge graphs. Siren enables real-time, explainable searches across massive, complex datasets, extracting only the most relevant entities and relationships for investigation. This feeds AI-driven analysis with precise, actionable subgraphs rather than overwhelming datasets.

Siren provides traceability, explainability, and auditability, ensuring analysts can uncover hidden connections, validate intelligence, and make decisions with confidence, and at scale. This capability is critical for government investigations, compliance and AI-driven intelligence workflows.

Renaud Delbru, founder of Siren, added, “Elastic’s investment validates our architectural vision, that effective AI-driven investigation requires the federation of search, graph operations, and natural language understanding. Together, we provide the structured foundation that allows AI to augment rather than replace human investigative judgment.”
