depthfirst is a San Francisco applied AI lab building an AI-native security platform that detects, triages and remediates software vulnerabilities before attackers can exploit them. Its 'General Security Intelligence' uses custom AI agents and purpose-trained security models to read a company's code, business logic and infrastructure, surfacing more true-positive vulnerabilities while cutting false positives and delivering developer-ready fixes.

Founded in 2021 by security veterans Shahar Ben-Hador and Barry Shteiman, the company aims to cut the alert noise that overwhelms security operations centers, escalating only real threats to human analysts and reducing analyst workload by up to 98%. It also folds in integrated log management to cut SIEM storage costs.
Amplifier Security
Amplifier Security is an AI-native workforce security company that turns the noisy gap between finding and fixing security problems into an automated, employee-friendly workflow. Its agentic platform builds a per-employee Human Risk Graph, then deploys AI agents that engage workers directly in Slack, Teams and the browser to remediate device, app, identity and behavior risks - with humans kept in the loop. Founded in 2023 by Shreyas Sadalgi (CEO) and Tommy Donnelly (CTO), the company has raised roughly $9M and counts security-industry founders and CISOs among its backers and early customers.
