Closure

Closure, also operating as Closure Intelligence, develops an AI-based "digital analyst" platform for law enforcement agencies in the United States. The software ingests case evidence by drag-and-drop or integration and then transcribes, translates, searches, organizes and analyzes it, with the stated aim of reducing evidence overload for police departments, district attorney offices and investigators. Advertised capabilities include analysis of jail communications (transcribing and analyzing large volumes of recorded jail calls), mapping and "pattern of life" reconstruction that converts ALPR hits, call detail records and points of interest into timelines, and review of search warrants, returns and productions. The platform processes multiple evidence types, including scanned case files, and supports 13 languages.

The company positions itself as purpose-built for public safety and prosecution workflows rather than as a general legal-tech or e-discovery tool. Security and compliance are central to its positioning: it reports SOC 2 Type II certification, independent audit against the FBI CJIS 6.0 security policy, HIPAA-compliant construction, and externally validated penetration testing. Its architecture is described as "Zero Access," under which Closure employees cannot access customer data by default and support access requires explicit customer authorization of cleared personnel, alongside AES-256 encryption with FIPS 140-3 generated keys, encryption in transit and at rest via HTTPS/TLS 1.2+, U.S. data residency, role-based access controls, single sign-on, multi-factor authentication and comprehensive audit logging.

Closure was founded in 2024 and is based in New York City, with job postings also listing San Francisco and remote locations. It participated in Y Combinator's Winter 2025 batch, where its YC-listed team size is 11 and its primary partner is Tom Blomfield.

Founding story

The founding team combines engineering and defense backgrounds, including Stanford, Palantir and Israeli Defense Forces experience. CEO Aaron Zelinger previously spent six years at Palantir and two years at Arena; CTO Gilad Levy served six years in the Israeli Air Force as a pilot and in cyber security, and worked at Spot.io (acquired by NetApp), Microsoft and Rivery (acquired by Boomi), holding an MSc in computer science from Reichman University and an MBA from Tel Aviv. The company's stated goal is to speed case closure through analytics and automation built for law enforcement.

Business model

Closure sells software to government law enforcement and prosecution agencies, which upload case evidence into the platform for automated transcription, translation, search and analysis. Job postings for founding forward-deployed engineer, deployment strategist and business development/account executive roles indicate a direct enterprise/government sales and deployment model.

Traction

Publicly cited users include the Placer County, San Mateo County, Del Norte County and San Luis Obispo County district attorney offices and the Anchorage Police Department. Testimonials describe outcomes such as rapid keyword search across 15-20 hours of recordings, analysis of 150 uploaded jail calls that surfaced PINs including one that unlocked a previously inaccessible phone, a four-year use-of-force analysis, identification of a potential victim or witness in a sexual assault case, and a case that resulted in a 35-to-life sentence. Y Combinator lists a team size of 11.
