Limbic

What Limbic does

Limbic is a clinical AI company that builds software for mental healthcare providers, headquartered in London with a US regional office in New York. Its product portfolio centers on two complementary offerings: Limbic Access, a web-based conversational AI for patient self-referral, eligibility checking, and diagnostic triage (the first AI mental health chatbot globally to achieve Class IIa UKCA medical device certification); and Limbic Care, a generative AI companion mobile app that delivers CBT between clinical sessions. Both products are powered by the Limbic Layer, a proprietary AI architecture that sits between users and large language models to enforce clinical safety, validity, and regulatory compliance on every interaction. Supporting tools include a Therapist Portal and Admin Portal for clinician workflow integration, plus a TORTUS-powered AI Scribe for automated clinical documentation added in June 2026.

The company sells exclusively through enterprise B2B SaaS contracts to NHS Talking Therapies services in the UK (45 trusts covering 45% of NHS England regions, with named customers including Everyturn, Living Well Consortium, NHS Bradford and Craven, Essex Partnership, Surrey and Borders, and Greater Manchester Resilience Hub) and, more recently, to US health plans, health systems, and behavioral health providers (Rogers Behavioral Health is the anchor US reference customer). Pricing is not publicly disclosed and is negotiated via multi-year software license agreements through a sales-led enterprise motion with "Book a demo" and "Talk to sales" CTAs. The company was founded in 2020 by a team of 10 PhDs, is privately held and venture-backed (Series A of $14M led by Khosla Ventures in March 2024), and has secured extensive regulatory and quality certifications including Class IIa UKCA, ISO 13485, ISO 14971, ISO 27001, Cyber Essentials, HIPAA, and GDPR compliance.
