Under Content Generation, it offers a Stealth AI Writer, Content Enhancer, and Content Humanizer. Polygraf AI targets organizations in regulated industries such as defense, finance, healthcare, and government, where data sovereignty and air-gapped deployments are a requirement. The platform is designed to counter threats related to synthetic content, misinformation, and data exfiltration through AI systems. The company has raised a $9.5M seed round led by Allegis Capital and holds AICPA SOC compliance certifications. Its advisory board includes former government and intelligence officials, including a former House Intelligence Committee Chairman and a former CIA Deputy Director, reflecting a focus on national security use cases.
