Investing in Depthfirst
Depthfirst, an AI‑focused security startup, announced its Series B funding and introduced dfs‑mini1, a specialized model that outperforms leading AI systems at detecting smart‑contract vulnerabilities while costing far less to run. The platform builds a semantic model of a customer’s environment, linking code, dependencies, and business logic to generate exploitability proofs and automated fix recommendations, dramatically reducing false positives. By moving product security from static scanning to context‑aware risk assessment, depthfirst aims to fill the market void left by dominant network, endpoint, and cloud security vendors. Investors see the company as a key player in the emerging AI‑driven application security space.
