SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.
SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.
Threat Disruption provides expert threat intelligence and conducts scaled operations against the adversaries attacking X. We investigate and disrupt threats across platform manipulation including coordinated networks of bots attempting to pollute the information space, compromises of accounts owned by high-visibility individuals and organizations, sensitive allegations carrying reputational, legal, or geopolitical weight, including suspected foreign-linked influence campaigns, as well as financial fraud, monetization abuse, and scam networks operating on and off X and other X Rules violations, including illegal activity and child safety.
We identify how adversaries circumvent our defenses, abuse product features and core services, and benefit from the abuse. Based on these investigations, we conduct sweeps to disrupt immediate threats and provide recommendations to product, engineering, and policy teams to squash systemic vulnerabilities.
Where appropriate, Threat Disruption also coordinates with law enforcement and other external parties to enhance detections and support prosecution of bad actors. Come help us defend the global town square.
