Open Source Security Needs to Catch Up—We Built the Engine to Do It
AI is accelerating both attackers and developers—but AppSec is in danger of being left behind.
While threat actors automate exploitation and engineering teams automate delivery, security teams are stuck manually managing open source risk: triaging findings, researching fixes, and coordinating upgrades across dozens of repos.
We believe this asymmetry is dangerous—and solvable.
But for AI to truly help security, it needs context.
That’s why we built Heeler. At the core is our context engine—ProductDNA—a system that understands how code runs in production. This context powers automation that’s accurate, safe, and useful:
(1) Prioritize real risk using runtime threat modeling
(2) Understand fixability by mapping upgrade paths and breaking changes
(3) Automate remediation via agentic workflows that generate validated PRs
(4) Enforce runtime-aware guardrails that warn or block risky changes
The result: developers move faster, AppSec focuses on what matters, and security finally benefits from the AI revolution.

Our story so far
How we got here
We’ve spent years on the front lines of application security. During that time, we witnessed firsthand the growing gap between security and development teams. The tools and processes available often left AppSec teams overwhelmed and under-resourced, while developers were racing against the clock to ship features.
We knew there had to be a better way—a way to bring security and development closer together, reducing the friction between them and amplifying their impact. That vision became the foundation of Heeler. Our shared experiences made it clear that security had to evolve beyond fragmented tools and manual processes. It needed to be part of the core workflow, fully integrated into how software was built and deployed.
We launched Heeler to solve the very challenges we faced. By unifying application, runtime, and business context, we’re driving a much-needed shift in the way security is approached—one that’s scalable, automated, and developer-friendly.
In June 2023 the four co-founders launched Heeler.
