Company Overview
About Depth First
Depth First (depthfirst) is an AI-native cybersecurity company founded in October 2024 by Qasim Mithani (CEO, ex-Databricks/Amazon), Daniele Perito (ex-Square/Block), and Andrea Michi (CTO, ex-Google DeepMind). Headquartered in San Francisco, the company builds General Security Intelligence (GSI), a platform that uses AI to scan codebases and infrastructure for complex vulnerabilities, prioritize real issues, and provide ready-to-merge fixes.
Business Model & Competitive Advantage
Depthfirst differentiates through an agentic AI approach that builds deep context on a company's code, infrastructure, and business logic rather than relying on pattern matching. Its agents uncover 8x more true-positive vulnerabilities than traditional static analysis tools while reducing false positives by 85%. Customers include Fortune 500 companies and fast-growing businesses like ClickUp, Lovable, Supabase, incident.io, and Moveworks.
Competitive Landscape 2025–2026
In January 2026, depthfirst emerged from stealth with a $40 million Series A led by Accel Partners. Less than 90 days later in March 2026, it closed an $80 million Series B, bringing total capital to $120 million. The rapid back-to-back rounds reflect strong demand for AI-native security solutions.
