"This financing provides us the capital to execute on our key strategic initiatives, as we expand the reach of our differentiated cardiac monitoring platform," said Robert Eno, Chief Executive Officer of HeartBeam. "We are especially pleased to have ClearCardio™, our first commercial customer, join as an investor. Their participation meaningfully validates our technology and its fit within the high-engagement preventive cardiology and concierge markets, while reinforcing our confidence in the growing demand for more accessible, actionable cardiac insights."
