Umaimah Khan
Umaimah Khan is the co-founder and CEO of Opal Security, a San Francisco identity security company building the controls that decide who - and increasingly what - can access an organization's systems. A homeschooled math kid who entered MIT at 16 and fell for cryptography, she did research embedded with government agencies including DARPA, then engineered infrastructure and security at two startups that became unicorns. She founded Opal in 2020 to treat authorization as the hard technical problem she believes it is, and has raised roughly $32M, including a $22M Series B in December 2023. Opal's customers include Cloudflare, Figma, Databricks, Scale AI, Grammarly and Perplexity.

Rick Caccia is CEO and co-founder of WitnessAI, the Mountain View-based AI security company that raised $85.5M total (including a $58M round from Sound Ventures and Ashton Kutcher in January 2026) and delivered 500%+ ARR growth in 12 months. A Silicon Valley native with multiple UC Berkeley degrees, Caccia spent two decades in cybersecurity product and marketing leadership at Palo Alto Networks, Google (founding CMO for Chronicle), Exabeam, Red Canary, ArcSight, and Symantec before pivoting to the CEO seat to build purpose-built security guardrails for enterprise AI.
