Biologix

Biologix is a Brazilian health-tech firm founded in 2015 with a mission to make the diagnosis and treatment of sleep disorders more accessible. The company was co-founded by Tácito de Almeida, an electronic engineer, and Dr. Geraldo Lorenzi Filho, a pulmonologist and the director of the Sleep Laboratory at the Heart Institute (InCor) in São Paulo. Almeida's personal, negative experience with a traditional, hospital-based sleep study for his own sleep apnea prompted him to seek a simpler method, leading to the partnership with Dr. Lorenzi, a leading sleep medicine specialist in Brazil.

The company's core offering is the Biologix Sleep Test®, a home-based, multimodal polysomnography for diagnosing snoring and sleep apnea. This system utilizes the proprietary Oxistar® sensor, a compact, wireless device developed and manufactured in Brazil, which integrates a high-resolution oximeter and an actigraph. The sensor is placed on the patient's finger and works in conjunction with a smartphone app (available for Android and iOS) to collect data overnight, including oxygen saturation, heart rate, movement, and, by using the phone's microphone, snoring intensity. The collected data is encrypted and sent to a cloud-based platform where artificial intelligence algorithms analyze it, generating a comprehensive report available to the healthcare professional within minutes.

Biologix operates on a business-to-business model, serving healthcare professionals and clinics who become accredited centers. These centers can choose between a monthly subscription for unlimited tests or a pay-per-use model, allowing them to generate additional revenue by charging patients for the test. The company offers two versions of its test: the standard Biologix Sleep Test® and the Biologix® Pro, which adds the capability to detect the risk of Atrial Fibrillation. The platform's scientific validity is supported by multiple clinical studies, demonstrating over 90% accuracy, sensitivity, and specificity compared to traditional sleep studies. As of early 2024, the company was conducting over 10,000 exams per month through a network of more than 4,100 accredited practices across Brazil.
