Summary
a16z Crypto released a personal and physical security guide tailored to technology and cryptocurrency professionals, particularly those attending industry conferences or traveling. The checklist was developed by the firm's head of security, identified as a former Secret Service agent, reflecting institutional-grade threat assessment principles adapted for the sector's specific risk environment.

The guide is structured around three foundational pillars. First, cultivating the correct mindset involves recognizing baseline behavioral patterns, mentally tagging anomalies, and prioritizing distance as a safety mechanism rather than engaging potentially threatening situations. The emphasis on scenario planning and early habit formation reflects a preventive rather than reactive security posture. Second, maintaining presence in public spaces requires balanced awareness—remaining alert without hypervigilance—while actively avoiding complete phone absorption and varying routine patterns to eliminate predictability. The guidance explicitly cautions against discussing sensitive business or asset information in shared spaces such as rideshares.

Third-stage recommendations address elevated-risk scenarios including evening outings and late-night transit. Specific protocols include shared location tracking with trusted third parties, pre-arranged separation contingency points with colleagues, and carrying defensive tools (flashlight or pepper spray) already deployed when walking alone after dark. The guide expressly prohibits public disclosure of cryptocurrency holdings or real-time location data, recognizing the intersection between digital and physical threat vectors in the crypto ecosystem.

The resource was packaged as a downloadable PDF and promoted through a16z Crypto's newsletter (a16zcrypto.substack.com), indicating distribution through professional channels including team communications, industry forums, and messaging platforms. The publication date and conference-travel framing suggest timing aligned with peak industry event season, positioning the guide as operational security infrastructure for a high-profile professional cohort.
