## About

DepthFirst AI, Inc. specializes in AI-driven software security solutions. Founded in 2024 by CEO Qasim Mithani, Daniele Perito and CTO Daniele Perito and headquartered in California, US. In March 2026, DepthFirst AI, Inc. raised USD 80 million in series B funding led by Meritech Capital Partners, with participation from Forerunner Ventures and The House Fund. Returning investors Accel, BoxGroup, Liquid 2 Ventures, Mantis, and ALT Capital Partners also participated in the round. The company plans to use the March 2026 Series B funding to expand its AI research team, train additional security models across new domains, and scale enterprise adoption of its AI-native security platform.

DepthFirst AI offers an AI-native security platform that integrates advanced security intelligence to help organizations identify and remediate software vulnerabilities effectively. The platform analyzes code repositories, infrastructure, and business logic to deliver actionable insights and fixes directly to developers' workflows. Key features include uncovering complex vulnerabilities that traditional scanners often miss, tracing attack paths, and validating the exploitability of security issues. Its modular architecture allows for rapid deployment and continuous learning. The company serves a diverse client base, including firms such as AngelList, Moveworks, and Persona, predominantly in North America and Europe.

DepthFirst AI generates revenue through subscription-based models for its security platform, serving business-to-business clients in the tech industry. Subscriptions offer access to core services, including General Security Intelligence and dynamic testing for running applications, ensuring ongoing protection against emerging vulnerabilities. Clients enter contracts that may include tiered pricing plans based on the scale of usage, such as the number of repositories analyzed or the volume of code reviewed. This structure allows flexibility in meeting the security needs of varying-sized companies.

The company plans to use the March 2026 Series B funding to expand its AI research team, train additional security models across new domains, and scale enterprise adoption of its AI-native security platform.
