What PromptArmor does

PromptArmor (legal entity Board Security, Inc.) is a San Francisco-based software company that builds an AI Risk Intelligence platform for assessing and monitoring third-party AI risk. The platform evaluates vendors across 26 risk vectors mapped to NIST AI RMF, OWASP LLM Top 10, and MITRE Atlas, runs daily continuous-monitoring scans across vendor ecosystems to detect AI scope changes, and maintains a living AI Vendor Inventory with discovery, enrichment, and risk tagging. An adjacent AI Transparency module generates automated model cards and surfaces buyer-engagement signals into Salesforce and HubSpot, and an Early Access Program offers beta modules for Security Operations and Governance. The company is privately held, founded in 2023, and operates with 1-10 employees.

The product is delivered as a hosted web application with Open API access and native connectors into incumbent TPRM, GRC, and security stacks (ServiceNow, ProcessUnity, Archer, Zscaler, Netskope). GTM combines direct enterprise field sales targeting Fortune 50, Am Law, healthcare, and financial services buyers with a channel program led by SHI and a research-driven community motion around vulnerability disclosures. Named customers include HubSpot, Ropes & Gray, Texas Mutual Insurance, Alteryx, Bill.com, GE HealthCare, Ogletree Deakins, and Prosus-Naspers, with the company claiming protection of more than $2 trillion in customer market cap.

The company monetizes through SaaS subscriptions sold via consultative enterprise sales with quote-based pricing tied to vendor portfolio size, users, and feature tiers; pricing is not publicly disclosed. The company raised a $3.2M seed round in April 2024 from Afore Capital, Liquid 2 Ventures, and Y Combinator, maintains SOC 2 Type II certification, and operates with no publicly disclosed revenue, ARR, or follow-on financing to date.
