Tangen Biosciences

Tangen Biosciences, Inc. is a molecular diagnostics company founded in 2013 by John Davidson and headquartered in Branford, Connecticut. The company focuses on decentralizing diagnostics by moving molecular testing from traditional laboratories to point-of-care settings like doctor's offices, pharmacies, and clinics in remote areas. The co-founders, including John Davidson (Chief Science Officer) and John Nobile, have extensive experience in developing next-generation DNA sequencing technologies at companies like Roche and Life Technologies. The leadership team was later joined by CEO Richard C. Birkmeyer, PhD, a seasoned executive with a track record of leading diagnostic startups to successful exits.

The company's core technology is the TangenDx™ platform, which consists of a portable, automated instrument called the GeneSpark™ analyzer and single-use disposable test discs. This platform utilizes isothermal nucleic acid amplification to rapidly detect targeted DNA and RNA from various patient samples, such as whole blood, swabs, and sputum, delivering results in under an hour without needing complex laboratory equipment or refrigerated reagents. A key differentiator is the system's ability to simultaneously detect a broad array of targets from a single sample with high sensitivity and a simple workflow.

Tangen Biosciences' business model centers on the development and sale of these diagnostic test kits for its platform. The company serves healthcare providers who require rapid, on-site diagnostics for infectious diseases. Its product pipeline includes tests for bloodstream infections (sepsis), respiratory viruses like SARS-CoV-2 and Influenza A/B, and antimicrobial resistance (AMR) gene panels. The firm gained significant attention during the COVID-19 pandemic, developing a point-of-care test and receiving federal contracts and an Emergency Use Authorization from the FDA. The business generates revenue through the sale of its GeneSpark instruments and the disposable assay kits. Tangen has successfully raised capital through multiple funding rounds, including a $46.6M total from investors like Connecticut Innovations, Leading Edge Ventures, and Parvizi Surgical Innovation, to scale manufacturing and accelerate clinical development.
