Glass Health

What Glass Health does

Glass Health is a private, San Francisco-based clinical AI company founded in 2021 that builds an LLM-based AI agent for evidence-based clinical decision support at the point of care. The platform unifies two core capabilities into a single workflow: Ambient Scribing, which captures patient encounters in real time and surfaces diagnostic insights, suggested history questions, and next steps during the encounter itself, and a Clinical Decision Support engine that drafts differentials (DDx), assessments and plans (A&P), and structured clinical documentation including H&Ps, progress notes, clinic notes, discharge summaries, prior authorizations, patient handouts, and handoff notes. The product also includes an Evidence-Based Clinical Reference function that returns cited answers from trusted medical sources, a 'Deep Reasoning' engine for multi-step clinical reasoning, and a Developer API with a dedicated EHR integration pathway.

The company operates a product-led, freemium go-to-market motion: clinicians can sign up directly on glass.health, begin ambient scribing for free, and self-onboard without enterprise procurement. A dedicated /pricing page implies paid clinician subscription tiers, and the Developer API supports API/platform licensing for institutions and third-party developers. Customer reach is described as 'thousands of healthcare professionals,' with named institutional logos including Yale School of Medicine, University of Pennsylvania, Stanford, Harvard Medical School, and Brown Health used primarily as credibility signals rather than disclosed enterprise contracts.

To date, Glass Health has raised approximately $7 million across three disclosed funding rounds — a $1.5M seed from Breyer Capital (January 2022), a $500K Y Combinator investment (April 2023), and a $5M round led by Initialized Capital with participation from Breyer Capital, Breyer Labs, and Y Combinator (September 2023). The company is led by co-founder and CEO Dereck Paul and co-founder and Head of Product Graham Ramsey, and competes in the Clinical Decision Support Systems market alongside incumbents such as UpToDate Expert AI, AMBOSS, ClinicalKey AI, OpenEvidence, Isabel, and DynaMed.

Revenue model

1. Freemium subscription: Free-tier onboarding via 'Start Ambient Scribing for Free' CTA on the website; users can self-sign-up and use the platform without an enterprise contract. Paid tiers implied beyond the free monthly query allowance referenced in user testimonials ('multiple queries for free all month long'). Recurring subscription revenue model.
2. Subscription (paid clinician plans): Paid subscription plans for clinicians seeking expanded usage beyond the free tier (pricing page exists on the site at /pricing). Recurring revenue stream.
3. Developer API / EHR integration licensing: Developer API and EHR integration offering implies potential API/platform licensing or per-seat enterprise plans for institutions embedding Glass into their systems.

Core offering

Glass Health is an AI-powered clinical decision support (CDS) platform that combines ambient scribing with large language model-based clinical reasoning to help clinicians draft differential diagnoses, assessments and plans, and structured clinical documentation during and after patient encounters. The platform offers a free self-serve tier for individual clinicians, paid subscriptions, and a Developer API with EHR integration for institutional distribution.

Product overview

Glass Health is a single unified AI-powered clinical decision support (CDS) platform that integrates two core capabilities into one workflow: Ambient Scribing for real-time clinical intelligence during patient encounters, and Clinical Decision Support for drafting differentials (DDx), assessments & plans (A&P), and structured clinical documentation. Built on a large language model-based AI agent, the platform exposes an Evidence-Based Clinical Reference function (with cited answers from trusted medical sources), Diagnostic Support and Treatment Planning modules, and a Documentation Drafting suite (covering H&Ps, progress notes, clinic notes, discharge summaries, prior auths, patient handouts, and more). Glass Health extends the platform with dedicated EHR Integration and a Developer API for embedding the capabilities into external workflows.
