About
Closure is a San Francisco-based legal technology company building the first digital analyst platform purpose-built for law enforcement — enabling police departments, prosecutors, and investigators to search, transcribe, translate, and analyze vast amounts of digital evidence (surveillance footage, witness interviews, body camera recordings, documents) that would otherwise require days of manual review. A Y Combinator-backed startup, Closure addresses the evidence overload crisis facing modern law enforcement: cases now routinely involve terabytes of digital evidence from phones, cameras, and IoT devices that overwhelm investigator capacity.

About
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter).

Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
