Value proposition
Comprehensive AI security platform that combines pre-deployment adversarial testing (Shade), runtime protection (Cygnal), and a global red-teaming community of 15,000+ researchers (Arena) to identify and block AI vulnerabilities before attackers can exploit them.
Products and solutions
Cygnal (runtime AI monitoring and protection - blocks adversarial inputs and unsafe outputs in production), Shade (automated adversarial red-teaming agent for pre-deployment and CI/CD testing), Arena (global AI red-teaming competition network with 15,000+ researchers), Adversarial Evaluation Services (custom benchmarks for frontier labs), AI Red-Teaming as a Service (dedicated adversarial assessment)
Unique value
Tests against attacks discovered by 15,000+ adversarial researchers—most of which haven't been published yet—rather than only known attack patterns, giving enterprises tomorrow's threat intelligence today.
Target customer
Enterprise organizations deploying AI agents and applications; frontier AI labs (model builders) needing pre-release safety evaluations; AI security researchers participating in red-teaming competitions.
Industries served
AI/ML (frontier model labs), Enterprise AI, Technology, Cloud Computing, Financial Services
Technology advantage
Built on a decade of pioneering adversarial ML research from CMU; cited in 11 frontier model system cards (Anthropic, OpenAI, Meta); network effects from 15,000+ red-teamers generating continuous threat intelligence; supported by Snowflake integration for native enterprise AI security.
How they differentiate
Unlike competitors that validate against known attacks, Gray Swan's threat intelligence comes from 15,000+ adversarial researchers continuously discovering novel vulnerabilities in Arena competitions. This offensive-informs-defense approach means they test against attacks most haven't seen yet. Also, they are the only AI security company trusted simultaneously by all major frontier labs as cited in model system cards.
Main competitors
Lakera, Mindgard, HiddenLayer, Protect AI (Recon), Robust Intelligence (acquired by Cisco), CalypsoAI
Key partnerships
Snowflake (native integration with Snowflake AI ecosystem), UK AISI (Agent Red-Teaming Challenge), cited in system cards of Anthropic, OpenAI, Meta, Google DeepMind
Notable customers
OpenAI, Anthropic, Meta, Google DeepMind, xAI, Snowflake, 20+ total customers across frontier labs and global enterprises
Major milestones
Founded September 2023 by CMU professors, Published foundational adversarial ML research, Launched Gray Swan Arena global red-teaming competition, Worked with OpenAI, Anthropic, Meta on pre-release model evaluations, Raised $5.5M seed round (2024), Raised $40M Series A co-led by Wing VC and Madrona (May 2026), Integrated with Snowflake AI ecosystem, Hired Rob Jenks as CSO (Jan 2026), Cited in 11+ frontier model system cards
Market positioning
The most trusted AI security provider for frontier labs, with unique access and relationships with every major AI model developer (OpenAI, Anthropic, Meta, Google DeepMind, xAI), positioning as the gold standard for adversarial AI evaluation and runtime protection.
Geographic focus
Global (headquartered in Pittsburgh, PA, USA; customers include US-based frontier labs and enterprises)
