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.
