Calibre Biometrics

Reaching out to my network with a to share an immediate investment opportunity with Calibre Biometrics.

As the Chief Evangelist and a founding team member since the beginning, over four years, I am excited to highlight our groundbreaking wearable breath-measurement device. This innovative technology delivers true metabolic and respiratory lab-grade data anywhere, anytime.

Our device is designed for athletes, biohackers, wellness enthusiasts, and healthcare professionals who can greatly benefit from real-time respiratory measurements. Existing solutions are often expensive, stationary, and complex, but Calibre offers a lightweight, affordable, and externally validated device that makes breath analytics accessible to the mass market.

With revenue accelerating, we are preparing for our Series A in 2026 and are currently raising a bridge round to support our next stage of growth. This funding will provide the necessary capital to increase manufacturing capacity. We are offering attractive terms for interested investors, with a minimum check size of $50K.

Our recent success has led to overselling on our stock, establishing demand. We are looking to overcome this growth challenge and lean in to our profitable business model

If you are interested in participating in this bridge/angel funding round, please reach out. Either I or our Founder, Udi Meirav, would be happy to discuss our product and business in detail.

We aim to close this round in less than 30 days and plan to keep the process simple with a convertible note featuring excellent terms. We appreciate sincere interest in investing.

For those seriously interested, we can share a detailed deck. You can contact me directly at [email protected] to get started.

So, time to be excited. Our launch is here. Our new app is a hit! Check out the next era of Calibre's capabilities and we are just getting started started!!
