Corti

What is Corti and who sells it?

Corti's homepage offers to "run frontier LLMs on sovereign EU infrastructure" and says it is trusted for more than 1 million interactions a week (corti.ai). Its About page says everything runs on Symphony, "our clinical-grade AI model," delivered through four capabilities: speech-to-text, text generation, medical coding and an agentic framework.

The company was co-founded by Andreas Cleve (CEO) and Lars Maaloe (CTO). Founding year is 2014 on Tracxn and PitchBook and 2016 in other sources. Funding includes a Series A of about $27M (EUR 22.8M) in September 2021 and a $60M Series B in September 2023 led by Prosus Ventures and Atomico, with Eurazeo, EIFO and Chr. Augustinus Fabrikker (TechCrunch, Business Wire). Reported totals range from over $86M to $100M. Corti says it has 95-plus employees in 9 countries and 3 offices.

The 2023 funding story mentions Corti's earlier public-safety work, which supported emergency dispatch calls. It no longer appears on the homepage.

What does the platform do?

The API suite covers speech to text, text generation, and medical coding, where "one API call returns structured predictions, supporting evidence, and a complete audit trail." An agentic framework comes with a library of agents, including an ICD-10 index navigator, a compliance guardrail, prior authorization, triage and initial assessment, an ICU admission summary and medication reconciliation. Named use cases are radiology report generation, pre-charting summaries, patient engagement and clinical decision support (corti.ai).

The About page makes benchmark claims: Symphony ranks first on OpenAI's HealthBench Professional, word error rate on medical speech is roughly 2% across 14 languages, and automated coding leads the next best system by more than 25 points. Corti also says it has 100 million or more patients served annually. All of these are vendor figures.

What are its regulatory and security credentials?

Corti Assistant MD has been registered with the UK MHRA as a Class I medical device since July 2025, and Corti says it was registered in the EU under the Medical Device Regulation in September 2025. The EU device class is not stated. The registration covers the Assistant, not the Symphony API, and it does not bind partners who build on the API. Corti offers partners a documentation pack aligned to MDR.

On security, the About page says HIPAA, GDPR, SOC 2, ISO 27001 and ISO 42001 are built in, with NHS DSPT, DTAC and EU AI Act coverage where relevant. A September 2025 Corti story gives dates: SOC 2 Type II renewed in June 2025, ISO 27001 certified in August 2025, BSI C5 Type II in June 2025, and external audits for ISO 13485 and ISO 42001 to begin in the second quarter of 2026. Corti's pages do not mention FDA.

How much does Corti cost?

Corti charges per use. Corti.ai/pricing gives $50 in free credits, valid for one year, then pay as you go. Speech to text costs $0.0065 per minute. Medical coding, agents and text generation cost $4 per million input tokens and $16 per million output tokens. An Acceleration Pack is $1,000 per month for 1,000 credits and 5 hours of developer support. Corti Advance, with custom bundles and sovereign cloud, is quoted. No per-clinician price exists for the Assistant.

What does the evidence say?

Corti says its research has appeared at NeurIPS, ICML, ICLR, ACL and npj Digital Medicine. All performance figures are Corti's own.

Who is it for?

A European health-tech startup that needs speech and coding APIs with EU hosting and a path to a regulated product is the natural customer. A hospital innovation team prototyping triage or summarization agents can start on the free credit allowance. An individual physician shopping for a scribe subscription has no product to buy here.

The verdict

Corti is an infrastructure vendor with a registered medical device and public rates. Build on it if you are a health-tech team that needs EU-hosted speech and coding APIs and can live with vendor-only benchmarks. Skip it as a clinician buying a scribe for yourself.
