Respirix

Respirix develops digital health software and hardware, including a point-of-care monitoring device. This technology offers proprietary, non-invasive insights into the pulmonary vasculature, specifically designed for monitoring conditions such as congestive heart failure. The integrated system analyzes key cardiovascular parameters to deliver actionable data for improved patient management.

The company was founded in 2015 by Daniel Burnett and Evan Luxon. They established Respirix based on the insight that non-invasive cardiovascular health monitoring could significantly enhance patient care. Their aim was to develop novel technological solutions for pulmonary and cardiac conditions, building an innovative diagnostic and monitoring platform.

Respirix targets healthcare providers and patients benefiting from continuous, non-invasive cardiac and pulmonary monitoring. The company's vision centers on improving patient outcomes through earlier detection and better management of cardiovascular diseases. They aim to make advanced physiological insights accessible, thereby supporting proactive health and treatment decisions.

Respirix is a San Francisco–based medtech startup building a non‑invasive, point‑of‑care cardiopulmonary monitoring device (Cardiospire) and accompanying software to detect early signs of congestive heart failure (CHF) decompensation and related pulmonary problems before patients become symptomatic[1][3].

High‑Level Overview

• Mission: Respirix aims to enable earlier, non‑invasive detection and management of cardiopulmonary deterioration to reduce hospitalizations and costs associated with CHF and related conditions[3][4].[3][4]
  - Investment philosophy / Key sectors (if treated as a portfolio target): Respirix sits at the intersection of medical devices, digital health/SaaS, and remote patient monitoring, attracting medtech accelerators and healthcare investors rather than generalist VCs[1][3].[1][3]
  - What product it builds (portfolio‑company view): Respirix developed the handheld Cardiospire device plus software that acquires cardiogenic oscillation data from a patient’s airway and provides proprietary insights into pulmonary vasculature and cardiopulmonary status non‑invasively[1][3].[1][3]
  - Who it serves: Primary users are CHF patients, clinicians and health systems focused on outpatient monitoring and early intervention to avoid hospital readmissions[3][4].[3][4]
  - What problem it solves: The product targets early detection of CHF decompensation and COPD exacerbations before symptom onset, with the stated goal of reducing substantial hospitalization costs tied to heart failure[3][5].[3][5]
  - Growth momentum: Respirix was founded in 2015, participated in MedTech Innovator’s accelerator (2019 cohort), has raised reported seed/incubator funding (~$1.3M) and has filed multiple patents related to cardiac monitoring, indicating early‑stage technical and commercialization progress[1][3][2].[1][3][2]

Origin Story

• Founding year and location: Respirix was founded in 2015 and is based in San Francisco, California[1][2].[1][2]
  - Founders and leadership: Public filings and company listings identify Daniel Burnett as Founder and Chairman and Eric Kriegstein as CEO in available profiles[2].[2]
  - How the idea emerged: The company pursued a non‑invasive approach to cardiopulmonary monitoring by sensing cardiogenic oscillations in the airway to detect physiological changes preceding CHF decompensation—a concept highlighted in its MedTech Innovator profile and accelerator materials[3][4].[3][4]
  - Early traction / pivotal moments: Respirix was selected for the MedTech Innovator accelerator (2019), won M2D2’s $200K challenge, reported raising approximately $1.3M via a securities filing, and has an active patent portfolio (multiple patents filed/february 2025 filings referenced), marking early validation and IP build‑out[3][4][1][2].[3][4][1][2]

Core Differentiators

• Non‑invasive sensing modality: Uses airway‑based cardiogenic oscillation measurements rather than implantable or purely hemodynamic catheters, positioning it as a lower‑risk, point‑of‑care tool[3][1].[3][1]
  - Combined hardware + SaaS model: The Cardiospire device plus cloud/software analytics aims to deliver actionable insights to clinicians and care teams, enabling remote or clinic‑based monitoring workflows[1][2].[1][2]
  - Early detection focus: Targets detection *before* symptom onset to prevent hospitalizations—a high‑value use case in heart‑failure management with sizable cost implications cited by the company and accelerator materials[3].[3]
  - IP position and accelerator support: Multiple patent filings and participation in reputable medtech accelerators (MedTech Innovator, M2D2, JLabs referenced as supporters/investors) provide technical and commercialization backing[1][3][4].[1][3][4]

Role in the Broader Tech & Healthcare Landscape

• Trend alignment: Respirix rides the convergence of remote patient monitoring, digital biomarkers, and value‑based care incentives that prioritize reducing readmissions and managing chronic disease outside the hospital[3][5].[3][5]
  - Timing: Aging populations, rising prevalence of heart failure, and payer pressure to lower avoidable admissions increase demand for tools that can detect decompensation earlier and enable proactive care[3].[3]
  - Market forces in its favor: Health systems and payers seek cost savings from reduced readmissions; regulators and reimbursement pathways are increasingly supportive of remote monitoring and digital therapeutics when clinical benefit is demonstrated[3][5].[3][5]
  - Influence: If validated clinically, Respirix’s non‑invasive approach could broaden access to hemodynamic‑style monitoring without invasive procedures, influencing device design choices and outpatient HF care pathways[1][3].[1][3]

Quick Take & Future Outlook

• Near term: Key milestones to watch are clinical validation studies demonstrating sensitivity/specificity for predicting CHF decompensation, regulatory clearances, reimbursement coverage, and scaling partnerships with health systems or remote monitoring platforms[3][1].[3][1]
  - Medium term: Success depends on demonstrating reduced hospitalization rates and cost savings in real‑world deployments; achieving that could position Respirix for commercial partnerships or additional funding to scale manufacturing and software operations[3][5].[3][5]
  - Risks and constraints: As an early‑stage medtech company, Respirix faces clinical validation, regulatory, and reimbursement hurdles as well as competition from implantable monitors, wearables, and other digital biomarkers—outcomes hinge on robust evidence and integration into clinical workflows[1][3].[1][3]
  - Strategic upside: If Cardiospire proves reliable and cost‑effective, Respirix could capture a meaningful niche in chronic cardiopulmonary monitoring and influence broader adoption of non‑invasive physiologic sensing in ambulatory care[3][1].[3][1]
