Doing What Matters

Innovation in inhaled anesthesia has been frozen for decades. Built by anesthesiologists, scientists, and investors who believe that progress in anesthesia still matters, we are breaking through barriers no one else is tackling.

From Discovery to Application

Laboratory

A Groundbreaking Discovery

Through a platform that predicts receptor activity from molar water solubility and guides the discovery of more targeted anesthetics, we are pioneering inhaled anesthetics that aim to reduce side effects and elevate the overall experience of anesthesia.

Promising Results

Among our emerging compounds, several have shown the ability to maintain normal blood pressure at anesthetic concentrations, providing hope for a new generation of inhaled anesthetics with improved hemodynamic stability.
