Lumius
Fast, smart, accessible 3D ultrasound for everyone
Spring 2026ActiveHealthcareMedical DevicesHard TechMedical DevicesDigital HealthDurham, NC, USA
Ultrasound today is still mostly 2D. Clinicians have to imagine the 3D anatomy in their head while also moving the probe at the same time. This makes procedures like vascular access hard to learn and perform consistently, especially for beginners. ~50% fail on their first attempt. Hospitals also spend millions each year on 2D ultrasound training. Meanwhile, existing 3D ultrasound devices can cost >10× as much.
Lumius is building fast, smart, and accessible 3D ultrasound systems to eliminate this 2D guesswork. Our technology shows a clear, real-time 3D view of what’s inside the body. It works over a large volume, not just a thin slice. The device is also affordable, compact, and portable.
We are starting with vascular access, especially central line. Future use cases include blood clot detection, tumor diagnosis, and biopsy guidance. Our long-term vision is a universal 3D ultrasound platform that brings easy-to-use, real-time imaging to a wide range of clinical and eventually consumer applications.

Market Opportunity
Hospital ultrasound is a multi-billion dollar market. The vascular access entry point is well-defined — central line placement has ~50% first-attempt failure rate, hospitals spend millions on training, and existing 3D ultrasound is cost-prohibitive (10x+ premium). Clear ICP (hospital proceduralists, ICU, ER) with measurable pain and a roadmap into blood clot detection, tumor diagnosis, and biopsy guidance expands TAM significantly.
Medium Signal
Founder Signal
Three PhD founders from Duke in directly relevant fields: ultrasound/photoacoustic imaging (Luca Menozzi CTO), BME (Tri Vu), and wearable electronics (Chenhang Li COO/CFO). Deep technical domain expertise is a real positive, but LinkedIn data is unavailable so we can't verify industry experience, prior roles, or any product shipping history beyond academia. All appear to be PhD-to-startup with no evident prior commercial experience cited.
Medium Signal
Competition
Existing 3D ultrasound incumbents (Philips, GE HealthCare, Supersonic Imagine) are expensive and non-portable. 2D ultrasound players like Butterfly Network have democratized cost but haven't solved the 3D problem. No direct low-cost 3D competitor is named, which is plausible but also possibly a research gap. Differentiation via affordability and portability is real if the hardware actually works, but hardware moat remains unproven at this stage.
Low Signal
Product
No live demo, no pricing page, no API docs, no customer logos, no revenue or usage metrics mentioned. Website tagline and description are concept-stage. No press coverage or traction signals found anywhere.
OverallC Tier
Three Duke PhDs with directly relevant technical expertise attacking a real, well-defined clinical problem — that's the best thing this application has going for it. But there is zero evidence of a working product, prototype performance data, clinical partnerships, or any traction whatsoever. No LinkedIn data available means we can't verify whether any of these founders have shipped hardware commercially before, which is a serious concern for a medical device startup. Medical device commercialization is notoriously slow and capital-intensive, and with no demonstrated product progress, this reads as a very early academic spinout that may not yet be ready for YC-stage velocity.
