What Biologix does

Biologix (legally Biologix Sistemas S.A.) is a São Paulo-based medical technology company that operates a multimodal home polysomnography platform for diagnosing obstructive sleep apnea. The platform combines two proprietary hardware sensors — the Oxistar 2 finger-worn high-resolution oximetry sensor and the optional Bodystar body position sensor — with a smartphone application and a cloud-based professional portal. During a sleep exam, the system records four simultaneous channels: peripheral oxygen saturation (SpO2), heart rate, hand actigraphy, and snoring via the phone microphone, and applies a proprietary AI algorithm to estimate total sleep time, classify sleep stages (Light, Deep, REM), analyze heart rate variability, and compute the Oxygen Desaturation Index adjusted to estimated sleep time (ODI Sono). The algorithm has been peer-reviewed in Scientific Reports (Nature) in 2024, and the Oxistar sensor stores personal data with AES-128 encryption under an LGPD-compliant privacy policy. The company was founded in 2015 by electrical engineer Tácito de Almeida and pulmonologist Dr. Geraldo Lorenzi Filho of InCor/HCFMUSP.

The flagship product, the Biologix Sleep Test (Exame do Sono Biologix), is delivered through a network of more than 9,000 accredited diagnostic centers across Latin America with localized country portals for Brazil and Chile. Complementary offerings include the Biologix Snoring Test (Teste do Ronco) for app-only self-screening without sensors, the Laudo Automatizado for automated specialist-signed report generation, the Biologix Academy education program, and the Biologix Portal with Patient Records (Prontuários) and CPAP Indication (Indicação de CPAP) workflows for prescribing professionals. Cumulative volume exceeds 600,000 home sleep exams across Latin America at a current run-rate above 21,000 exams per month, with the company citing +90% accuracy in OSA diagnosis versus clinical studies.

Biologix generates revenue through a combination of hardware sales or loaners of Oxistar 2 and Bodystar sensors, per-exam diagnostic fees paid by accredited centers for each Biologix Sleep Test processed through the cloud portal, subscription or active-plan fees for prescribing professionals accessing premium portal features, and distributor or wholesale revenue in Latam markets. The company was founded in 2015, received two FAPESP PIPE Phase III grants plus investment from Hospital Israelita Albert Einstein and a physician group in 2019, and added a $1.2M round in May 2024 led by Hospital Israelita Albert Einstein and Kortex Ventures. Pricing is quote-based and not publicly listed, with intake routed through a "Quero ser um Centro Credenciado" consultant funnel across categories including sleep medicine, ENT, cardiology, pulmonology, neurology, dentistry, and health plans.

Revenue model

1. Hardware sales — Oxistar® 2 and Bodystar® sensors: Sale/loaner distribution of proprietary finger oximetry (Oxistar 2) and position (Bodystar) sensors used by accredited centers and patients to perform the home sleep exam. Product is shipped/handed to patients via Centros Credenciados and recovered after the exam.
2. Per-exam diagnostic service for accredited centers: Centros Credenciados (clinics, physician offices, sleep labs) purchase access to the Biologix platform and pay for each Biologix Sleep Test (Exame do Sono Biologix®) and Laudo Automatizado processed via the cloud portal. Usage-based revenue tied to the volume of home polysomnography exams performed.
3. Subscription / portal plans for prescribing professionals: Active plans for prescribing healthcare professionals (e.g., physicians/dentists) unlocking portal features such as Prontuários and the CPAP Indicação workflow. Recurring SaaS-style revenue layered on top of per-exam fees.
4. Distributor / channel revenue: Indirect distribution via "Distribuidores" partners in Brazil and Latam (separate country portals such as portal.biologix.cl for Chile) generate wholesale/buy-and-resell revenue.
