PALO ALTO, Calif., March 18, 2024 (GLOBE NEWSWIRE) — Hippocratic AI, the developer of the first safety-centric large language model (LLM) for healthcare, today announced a $53 million Series A funding round. announced the end of The $500 million valuation brings the total funding to $120 million. Today, the company also released its first product for Phase Three safety testing: a staffing marketplace for healthcare where health systems, payers, and others can “hire” generative AI agents that can Completes high-risk, non-diagnostic, patient-facing healthcare tasks. To help address the major shortage of health care nurses, social workers, and nutritionists in the United States and around the world. The new capital will be used to fund these safety tests and further develop the product.

The round was co-led by PremG Invest and General Catalyst, along with SV Angel and Memorial Hermann Health System, as well as existing investors Andreessen Horowitz (a16z) Bio+Health, Cincinnati Children’s, Wellspin Health, and Universal Health Services (UHS). ) participated.

The company was founded on the belief that generative AI has the potential to improve access, equity and outcomes in healthcare but must be developed and deployed safely and responsibly.

The team has the potential to transform healthcare with LLMs that are safe and effective. We are better for patients around the world.” Looking forward to working with this passionate and talented team to deliver results.”

“Since founding Hippocratic AI a year ago, the company has trained its core model, achieved a critical safety margin, identified new use cases to solve the healthcare staffing crisis, and Partnering with 40 health systems, payers, and digital health companies, said Hemant Taneja, CEO and managing director of General Catalyst. And because of the strategy has developed rapidly. To make the health care system more efficient, affordable and equitable.

Today the company begins the next phase of its responsible AI journey by releasing its first product for Phase III safety testing. The company has launched a clinician-driven safety testing system for LLMs. Phase I testing was conducted by lead physicians and nurses (<50) to ensure that the agent completes all critical checklist items with the patient for a specific use case. Phase II testing requires testing 1000+ licensed US nurses, and 100+ US licensed doctors interacting with AI while acting as patients. Phase Three testing, which begins now, requires testing to be completed by 5,000 licensed nurses, 500 licensed physicians, and the company's health system partners.

The product is a new staffing marketplace where health systems, payers, and others can “hire” autopilot generative AI-powered agents to help solve the massive health care staffing crisis. Provide low-risk, non-diagnostic, patient-facing services. This marketplace is part of the company’s vision of how creative AI can deliver superstaffing and healthcare abundance and equity for the first time in history. Early roles include chronic care management, post-discharge follow-up for specific conditions such as heart failure and kidney disease, as well as social determinants of health and health surveys, health risk assessments, and preoperative access. However, these agents will not be allowed to interact with patients unsupervised until the third phase of safety screening is completed.

The company decided to move into Phase Three testing due to the promising results of Phase One and Two testing. In these early stages, 1002 US licensed nurses and 130 US licensed physicians were asked to act as patients and talk to company agents about various use cases. After each encounter, they were asked to evaluate the product on subjective and objective safety measures and compare the product to real nurses and other LLMs such as GPT4 and LLaMA 2 70B chat. The results of these studies are presented in a paper released today called Polaris: A Safety-Based LLM Constellation Architecture for Healthcare. Some highlights of the paper include:

These successful benchmarks are the result of Hippocratic AI’s unique three-part approach to security, consisting of: (1) 70B-100B core models trained using evidence-based content; (2) a novel constellation architecture with multiple models containing over a trillion parameters, in which the primary LLM was monitored by multiple expert support models to improve clinical accuracy and substantially reduce hallucinations; goes (more on this architecture in the Hippocratic Treatise); (3) Built-in guardrails that bring in a human supervisor when needed.

In addition, product development is guided by several Hippocratic AI oversight groups, including a Safety Governance Council, Physician Advisory Counciland a Nurse Advisory Councilwhich brings together respected physicians and registered nurses from leading health systems and digital health companies such as Cleveland Clinic, Nicklaus Children’s Hospital, Teladoc Health, WebMD, Massachusetts General Hospital, University of Illinois Health System, and more.

For the third phase of testing, Hippocratic AI will ask its 40+ partners to thoroughly test the safety of this novel generative AI-based product. These partners include HonorHealth, Cincinnati Children’s, OhioHealth, Roper St. Francis Healthcare, Universal Health Services, ELNA, SonderMind, Vital Software, Capsule, Evernow, HarmonyCares, Guidehealth, University of Vermont Health Network, Memorial Hermann Health System, Friends Health System and more.
