About Heeler
At a glance
Heeler is a cybersecurity company specializing in Application Security, founded in 2023 and headquartered in Bethesda, United States. It has raised $8.5M in total funding, employs about 24 people, and is privately held.
Heeler provides an application security platform focused on managing open source security risks through context-driven automation. The company's core technology is ProductDNA, a context engine that analyzes how code runs in production environments to enable more accurate security decision-making. The platform addresses open source vulnerability management by combining application, runtime, and business context to help security teams prioritize threats, understand fixability, and automate remediation. Key capabilities include runtime threat modeling for risk prioritization, mapping upgrade paths and breaking changes to assess fixability, agentic workflows that generate validated pull requests for automated remediation, and runtime-aware guardrails that warn or block risky changes. Heeler targets application security teams and development organizations dealing with the challenge of managing open source dependencies across multiple repositories. The platform aims to reduce manual triage work while enabling developers to maintain velocity. The company was founded in June 2023 by four co-founders with backgrounds in application security who identified gaps between security and development teams in existing tooling and processes. The solution integrates into software development workflows to provide automated vulnerability remediation while maintaining safety through validation. Heeler is backed by Greylock and Storm Ventures.
