Security Startups

StackHawk

Developer-first API DAST that runs in CI so AI-generated endpoints get tested before they ship.

Proof of life. Raised $12M strategic round from Sapphire and Costanoa, total $47.3M, May 2025

About StackHawk

StackHawk turns OpenAPI and running services into automated security tests that engineers own, not a quarterly pentest PDF. Findings come with reproduction steps aimed at the PR, which is the only place a 100:1 developer-to-AppSec ratio has a chance.

The 2025 raise is explicitly about keeping that loop intact when Cursor and Copilot are writing the API surface overnight.
