To whom it may concern,
This letter serves to confirm Closure Intelligence, Inc. (“Closure”) as a sole source provider of specialized investigative and prosecutorial analytical software—its Digital Analyst platform—for the lifecycle of investigations & prosecutions.
Closure’s Digital Analyst delivers an integrated suite of proprietary analytical tools for the unique demands of analysts, investigators, administrative staff, and prosecutorial staff—who regularly must integrate, organize, and interrogate large volumes of evidence across myriad formats and source systems, and then convert finished outputs into prosecution-ready artifacts.
Closure enables investigators and prosecutors to proactively transcribe, translate, search, analyze, summarize, aggregate, reformat, and verify evidence related to specific criminal prosecutions, within a single platform.
This integration of capabilities is specifically engineered to accelerate investigations and prosecutions, reduce manual review burdens, surface evidentiary insights, and facilitate the exploration of alternative and/or exculpatory hypotheses. Closure also enables post-investigative functions, such as exhibit creation, document redaction, and more, within a single analytical interface.
Examples of specific capabilities that Closure performs under a single, unified interface include (but are not limited to) the following:
Closure Intelligence, Inc. 1
Multi-Modal Evidence Analysis
● Semantic Search: Rather than relying on keyword matching across documents and cases, Closure performs concept searches across thousands of pages of documents, images, audio, videos, phone extractions, and other media. ● Audio Intelligence: Closure transcribes, translates, and searches tens of thousands of hours of recorded communications, with capabilities and auditability tailored to investigative and prosecutorial contexts, across tens of languages.
● Video Intelligence: Closure searches, bookmarks, and summarizes video footage, enabling investigators to pinpoint relevant evidentiary insights while reviewing hours of video footage.
● Mapping & Pattern-of-Life Analysis: Closure can map geographic and temporal events in a map-based view, such as Call Detail Records (CDRs), Automated License Plate Reader (ALPR) information, and device metadata (e.g.
EXIF), helping generate verifiable timelines and recreations of movement for investigators and prosecutors.
Investigative Workflow & Drafting
● Warrant Drafting: Closure enables investigators to generate verifiable drafts of search warrants for specific types of evidence, specific to the context and requirements of each document type and the available case evidence. ● Interview & Interrogation Processing: Closure processes interviews and other information to retrieve relevant facts, to help detectives and investigators write summaries and reports.
● Warrant Returns: Closure ingests, indexes, parses, and analyzes warrant returns from common social media and cloud providers, enabling investigators to interrogate lawfully obtained data related to their cases.
Evidence Ingestion & Organization
● Case Organization: Closure automatically stores, summarizes, and organizes the evidence related to a given criminal incident to improve searchability and discoverability of content.
● Email Search: Closure ingests, indexes, parses, and analyzes email data, such as data from Microsoft Outlook or Google Mailboxes, to assist prosecutors and investigators in their review of email-based evidence.

● System Integration: Closure integrates with existing source systems, including Evidence Management & Case Management Systems, to augment investigative reviews with relevant departmental data.
Administrative & Post-Investigative
● Redactions & Pseudoanonymization: Closure redacts documents and other files to remove identifying information, with customizable instructions to process the redactions, supporting ad-hoc public records requests. ● Exhibit Creation: Closure generates downloadable/exportable exhibits, such as PowerPoints and timelines, that can be used across a variety of contexts. ● Citations & References: Closure provides granular citations for all results provided, including audio, video, spreadsheets, text messages, and more, ensuring traceability and verification back to source evidence for all details provided.
Governance & Collaboration
● Secure Intra-Agency Collaboration: Law enforcement can share analyses performed and cases organized by Closure with other approved government users. This is highly configurable by role (Role-Based Access Control), policy, and/or on a case-by-case basis.
● Secure Inter-Agency Collaboration: Closure enables auditable, highly configurable case and evidence sharing across agencies. This is customizable to ensure compliance with local laws and customs and specifically penetration tested to avoid common threat escalation vectors.
● Full Scale Auditability: Closure enables full auditability of queries made, by investigator, to support compliance with emerging state and federal requirements around the use of artificial intelligence in law enforcement and prosecutorial contexts — such as California’s PC 13663, which represents a leading example of the type of AI governance legislation that other states are expected to adopt.
● Zero Access Architecture: Closure follows CJIS-mandated encryption practices, and extends these to ensure only the authorized law enforcement users involved may access agency evidence. By policy and technical implementation, Closure support and engineering do not have default access to case evidence.

This unified capability set enables Closure to expedite the identification and analysis of specific, citable textual passages, images, utterances, and more, critical to investigations and prosecutions. It also enables Closure to generate drafts of court exhibits that can be used to further a prosecution.
Closure has therefore been tasked by law enforcement to support numerous criminal investigations & prosecutions, including by helping identify “hidden” admissions of guilt, unearth exculpatory evidence, clarify the status of previously tested or untested physical evidence, build timelines, generate custom visualizations, review digital forensics, write draft reports and warrants, identify connections across cases, and much else.
JUSTIFICATION FOR SOLE SOURCE AWARD
As part of its normal business practice, Closure invests in understanding the capabilities of existing law enforcement software offerings. This includes online or open-source review of capabilities, proactive inquiries of vendors, interviews with law enforcement experts, and attendance at trade shows.
For example, Closure has thoroughly surveyed the field of available products at industry conferences — e.g., International Association of Chiefs of Police (IACP) in Boston, Massachusetts in 2024; at the California District Attorneys Association in Palm Desert, California 2025; at the California Homicide Investigators’ Association in Las Vegas, Nevada in 2025; at International Association of Chiefs of Police (IACP) in Denver, Colorado in 2025; at the California Robbery Investigator’s Association (CRIA) Conference in Reno, Nevada in 2026; at the Garden State Cold Case Conference in Atlantic City, New Jersey, in 2026; and at the Association of Prosecuting Attorneys Domestic Violence (APA DV) Conference in Salt Lake City in 2026, as well as other events. We have also attended informational sessions with numerous software vendors for law enforcement during the course of our research and product development.
As of April 28, 2026, our analysis has concluded that there are many other analytics vendors across the law enforcement technology ecosystem, including:
● Point Solutions: Pertaining to specific types of evidence or specific workflows.
These include transcription engines, document review platforms, device imaging

and extraction companies, call detail record visualizers and notification engines, video analysis tools, redaction products, timeline builders, and much else. ● Case or Records Management Solutions, using AI: Existing Records Management Systems or Case Management Systems that organize existing reports and data, often layering in an AI component for case summarization or question answering.
● AI Evidence Management Solutions: Products that seek to rank files of relevance for law enforcement using artificial intelligence into a visual interface, with summaries of each case file. Similar to existing Digital Evidence Management Solutions, but with AI affixed to them.
● Data Integrators: Solutions that integrate multiple systems of record, such as Records Management Solutions, Computer Aided Dispatch systems, and Automated License Plate Readers, into a single pane of glass, generally with an emphasis on recurring feeds of data.
● Large Language Model (LLM) Providers: Infrastructure providers who train and deploy general purpose large language models, with a focus on software development and consumer markets.
However, these point solutions, case management systems, records management systems, evidence management solutions, data integrators, and infrastructure providers fall short of Closure’s robust approach across analytical tasks, referenced above, across the lifecycle of an investigation & prosecution.
To the best knowledge of Closure management as of time of writing, there is no other vendor that offers all the functionality provided by Closure for investigations and prosecutions, within a single user interface and sets of workflows, specifically for utilization by prosecutors and their counterparts within local law enforcement agencies, State Investigative Agencies, District Attorneys, Prosecuting Attorneys, Commonwealth Attorneys, States Attorneys, and Attorney Generals.
To the best of our knowledge, Closure has made a good-faith effort to survey the market as described above; we welcome any agency to conduct independent market research to validate this conclusion.
