7AI
7AI is a Boston-based cybersecurity company building an agentic security platform that deploys autonomous, reasoning-based AI agents to take over the repetitive investigation work that overwhelms security operations centers. Founded in 2024 by Cybereason co-founders Lior Div and Yonatan Striem-Amit, the company ingests alerts from a customer's existing security tools, triages and investigates them at machine speed, and surfaces only real threats with full context and recommended actions - cutting mean time to respond from hours to minutes and eliminating the bulk of false positives. In December 2025 it raised a $130M Series A, described as the largest cybersecurity Series A on record.
Impart Security
Impart Security is a San Francisco cybersecurity company building a unified runtime protection platform for AI, APIs, and web applications. Founded in 2020 by Signal Sciences veterans Jonathan DiVincenzo, Marc Harrison, and Brian Joe, the company merges WAF, API security, Cloud Application Detection & Response, and AI Runtime Protection into one engine that runs autonomous defense agents inside production traffic.
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.
WitnessAI
WitnessAI is an enterprise AI security and governance platform that helps organizations safely deploy AI at scale. Built on three pillars - Observe, Protect, and Control - its platform provides real-time visibility into all AI interactions (employee tools, internal models, AI agents, MCP servers), detects and blocks prompt injections and jailbreaks with over 99% accuracy using intent-based ML models, and enforces behavioral policies without code changes. With $85.5M in total funding, 500% ARR growth in 2025, and customers across financial services, telecom, airlines, and automotive, WitnessAI is positioning itself as the confidence layer enterprises need to move from AI experimentation to production deployment.
Rick Caccia
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.
