Liminal

What Liminal does

Liminal (legal entity Liminal AI, Inc., incorporated in Colorado; previously known as Tenon) is an AI security, governance, and enablement platform purpose-built for regulated enterprises. The platform sits between users and external large language models, applying a proprietary detect-protect-rehydrate architecture that context-aware masks sensitive data before prompts leave the enterprise and rehydrates protected terms on return, preserving prompt intent and user experience. Core products include Liminal Spaces (multi-model chat), Liminal Enterprise Search (RAG over organizational data), Liminal Console (governance and observability), Liminal Insights (usage analytics), Custom Assistants, an SDK in Python, TypeScript, and .NET, and desktop and browser deployment options. The platform wraps models from OpenAI, Anthropic, Perplexity, and Google into a single governed environment.

Liminal sells primarily to regulated verticals — banking and credit unions, healthcare, financial services, insurance, biotech and life sciences, and education — addressing HIPAA, GLBA, SOX, PCI DSS, and FERPA-driven constraints on AI adoption. Revenue is generated through flat-rate per-seat annual subscriptions, with quote-based enterprise contracts and a growing channel motion through Managed Service Providers. Disclosed enterprise customers include Delta Dental of New Jersey/Connecticut and Northern Arizona Healthcare; the company is also a Temasek-founded venture creation group that has incubated motif, an AI wealth advisory platform whose Clarity product is contracted by financial institutions covering over 1.5 million end users and billions in assets under management.

The company has raised approximately $30M+ in disclosed funding across an oversubscribed $5M+ seed (June 2024, led by Fin Capital), an $8.5M Series A (April 2025), a $4.7M Elevation Capital-led tranche (April 2025), and an additional ~$11.98M raise (November 2025). It holds HIPAA, SOC 2 Type 1, and SOC 2 Type 2 certifications, with ISO 27001, HITRUST, and NIST AI RMF alignment in progress, and is built on ServiceNow. Operational headquarters are in Denver, Colorado, with 11–50 employees.
