Happy Monday and welcome back to Early Access by Coeus Collective Ventures: the newsletter where you get an inside look into a promising company in our network.

This is a special edition because it serves as the finale for our series of showcasing companies featured in our Capital Calling video podcast!

As of today, all episodes of Capital Calling are now available on our @CoeusCollective YouTube channel and all podcast platforms.

Developed in partnership with the NYU Stern School of Business’ Berkley Center for Entrepreneurship, the show peeled back the curtain on what it is like for startups to pitch directly to investors, and gave an inside perspective on investors’ opinions about the pitch they just heard.

From RIFT’s GPS-free geolocation infrastructure, to Braintrance’s $5M fundraise, to GAIAN’s energy-producing MOONWKR sneaker, Early Access has been there to supplement nearly every Capital Calling episode.

Today, the series concludes with Vital Audio.

What if a voice recording of only 8 seconds could have a meaningful impact on whether a life could be saved by a medical professional?

Vital Audio makes this impact possible, because when the stakes are highest, every second counts.

Let’s get to it.

On to the newsletter!

Despite the rapid growth of digital health and remote patient monitoring, cardiovascular assessment remains surprisingly analog. Patients still rely on episodic clinic visits, specialized hardware, and expensive diagnostic workflows to detect conditions that can emerge unpredictably between appointments. For high-risk populations, especially those susceptible to atrial fibrillation (AFib), heart failure, or pulmonary complications, this creates a dangerous blind spot. Significant events can occur silently, with little to no visibility until symptoms escalate into emergencies.

Vital Audio is building a fundamentally different approach. Rather than relying on wearables or hospital-grade equipment, the company turns ordinary microphones into biometric monitoring systems capable of extracting clinical signals from just eight seconds of voice. Their proprietary algorithms analyze speech to derive heart rate, heart rate variability (HRV), and rhythm assessments, transforming voice into a scalable diagnostic interface.

The implications are substantial. Traditional cardiac monitoring remains expensive and operationally burdensome, limiting accessibility and frequency of use. By embedding monitoring into devices people already use daily, from smartphones to telehealth systems and even vehicles, Vital Audio is positioning itself at the intersection of healthcare infrastructure, voice AI, and preventative medicine.
