Closure

What do they actually do

Closure provides a restricted cloud tool that acts like a “digital analyst” for police and prosecutors. It automatically transcribes and translates audio, indexes and searches files, and helps organize and analyze large, messy evidence sets so investigators can find relevant material faster Closure homepage / PromptLoop directory.

Today it’s used by local police departments, district attorneys’ offices, and major‑crimes/cold‑case teams, with the company actively training investigators and working with early partner agencies. Access is controlled via a secure login, consistent with handling sensitive evidence, and the team is part of YC’s Winter 2025 batch while expanding across law‑enforcement customers Y Combinator / LinkedIn / restricted login.

Who are their target customer(s)

• Local police detective (major‑crimes/homicide): They’re buried in interview audio, jail calls, and scanned reports; manual transcription/search takes days and important connections are easy to miss. They need faster ways to surface and export usable evidence.
• Cold‑case investigator: Decades‑old paper files and mixed digital formats make a full re‑review impractical. Multilingual material and poor OCR quality raise the risk of overlooking key links.
• District attorney/prosecutor: Assembling court‑ready evidence packets from many sources is slow and error‑prone. They need organized, searchable records to support charging decisions and trial prep.
• Records/evidence custodian (small/mid‑sized agency): A small team must process sensitive material with controlled, auditable access. Current tools require manual steps and ad‑hoc sharing that create risk and delays.
• State/federal task‑force analyst or digital forensics unit: They manage large, cross‑jurisdictional datasets. Bulk processing, translation, and reliable searchable indexing are needed so cases don’t stall waiting on manual review.

How would they acquire their first 10, 50, and 100 customers

• First 10: Run high‑touch 3–6 month pilots with existing engaged departments, deliver hands‑on training, and produce a few prosecutor‑ready evidence packets to prove courtroom value Closure homepage / LinkedIn.
• First 50: Convert pilots into regional clusters via referrals and train‑the‑trainer workshops; use case studies and short‑term bundled pricing for neighboring jurisdictions to speed procurement Y Combinator / PromptLoop.
• First 100: Pursue state‑level and grant‑funded pilots, add a lightweight procurement/compliance function to satisfy security/legal reviews, and partner with evidence‑management vendors/forensic consultants to piggyback on existing purchasing workflows Y Combinator / restricted login.

What is the rough total addressable market

Top-down context:

Closure sits within the digital evidence/evidence‑management software market, estimated at roughly $7.5–$9.7B globally today, with North America around $3.6B in 2024 Grand View Research / Mordor Intelligence.

Bottom-up calculation:

A practical SAM proxy: target 3,000–5,000 investigative and prosecutorial units in the U.S. (from ~18,000 agencies and 3,144 counties) at an average $25k–$75k annual subscription for evidence transcription/search/analytics, implying roughly $75M–$375M in near‑term serviceable spend FBI UCR / U.S. Census.

Assumptions:

• Focus on larger municipal/county/state/federal units handling serious crimes/cold cases (a subset of total agencies).
• Average annual software spend of ~$25k–$75k per unit for analytics/transcription/indexing (excluding hardware/storage).
• Adoption limited by procurement/compliance and incumbents, growing with training/integrations FBI CJIS.

Who are some of their notable competitors

• Axon (Axon Evidence / Evidence.com): Large DEM platform tied to Axon capture hardware; offers storage, transcription, automated redaction, and case sharing—strong where agencies already run Axon end‑to‑end Axon Evidence.
• Veritone (aiWARE / iDEMS / Veritone Redact): AI media‑processing and redaction suite for public safety with transcription, tagging, and CJIS/FedRAMP hosting options—competes on automated audio/video processing and workflows Veritone.
• Palantir (Gotham / Foundry): Enterprise data fusion and investigative analytics used by large agencies to connect disparate records; overlaps on speeding investigations but is broader, cross‑system integration‑focused Palantir Gotham.
• Motorola Solutions (CommandCentral / Evidence): Integrated CAD/RMS and evidence management with investigative tools; attractive to agencies standardizing on a single vendor for end‑to‑end public‑safety software Motorola Solutions.
• NICE Public Safety (Evidencentral / NICE Investigate): Digital evidence and investigation platform with automated case building, link analysis, and redaction—directly competes on organizing evidence and preparing prosecutorial packages NICE Public Safety.
