Share rich HTML/Markdown securely behind company auth

Many engineering and product teams at mid-market and enterprise companies struggle to publish rich HTML or enhanced Markdown artifacts—specs, runbooks, and interactive product docs—behind corporate identity systems without exposing IP or bypassing compliance. The problem is acute for organizations that generate content programmatically with LLMs and need per-org access control, auditability, and safe rendering to prevent XSS and data leaks. You could build a security-first hosted service with optional single-tenant or VPC deployment that renders rich HTML/Markdown, supports interactive widgets, and enforces SAML/OIDC SSO, SCIM provisioning, RBAC, encryption-at-rest, and comprehensive audit logs; provide SDKs, CI/CD integrations, and a safe rendering engine that strips or policies third‑party scripts. Offer clear enterprise onboarding patterns (SAML metadata exchange, PrivateLink, or a self-hosted container) and pricing aimed at a $30K ACV for mid-market customers to keep sales focused and measurable. This market is attractive now because LLMs are making rich, repeatable HTML artifacts common, SSO/identity standards are broadly adopted, and teams are shifting toward interactive docs; that combination increases demand for secure publication workflows. The math is compelling: roughly 300,000 mid-market and enterprise organizations at a $30K ACV implies a $9.0B addressable opportunity, with a market score that justifies investment but requires disciplined execution. To stand out you must be relentlessly enterprise-first—demonstrate SOC 2/ISO controls, provide per-tenant isolation options, hardened renderer policies, and low-friction SSO/SCIM setup so engineering teams can pilot quickly. Expect real challenges: medium competition, non-trivial engineering work to prove the renderer safe at scale, and long procurement cycles; if you can move initial customers to pilot in 60–90 days and prove compliance and operability, the revenue potential is realistic.
