Intelligence without exposure
Stirling builds military-grade PDF security and intelligence infrastructure.
"The requirements were simple: Give us the smartest AI on the planet to process documents, but cut the cord to the internet."
Matt Joseph, Stirling CEO
The Origin
Stirling's business was architected to solve a critical gap in the defense sector: How do you perform advanced operations on classified documents that can never see the light of day?
Sending files to the cloud for OCR, redaction, or extraction was a security violation. Manual processing was impossible at scale. Industry leaders needed a self-hosted option they could trust.
The Architecture
We designed Stirling to pass the strictest security clearance and meet the highest intelligence standard at the same time. Instead of relying on external APIs, Stirling deploys a complete document processing core directly to your infrastructure. All PDFs stay completely private.
The Standard
Today, Stirling is the open-source standard for private document operations.
Maintained by the engineers behind the world's most popular PDF container, our infrastructure now powers the Fortune 500, rigorous government agencies, and privacy-conscious developers worldwide.
