PreDxion Bio

PreDxion Bio is working on a rapid saliva-based antigen test for the detection of SARS-CoV-2 S-protein in asymptomatic and presymptomatic patients. Our technology is uniquely capable of being scaled to 10's of millions of tests of days using semiconductor fab processes, a scale of testing necessary to better inform public health officials and policymakers and enable contact tracing at scale. PreDxion Bio's origins are in critical care: our original technology is a rapid, near real-time cytokine

PNOĒ

PNOĒ enables health professionals to provide science-backed bio-optimization through breath analysis. For 100+ years, breath analysis (AKA metabolic testing, VO2max) has been the gold standard in anti-aging quantification, nutrition prescription, and evaluation of most critical systems, including the heart, lungs, cells, and nervous system. Until recently, it was only available in sophisticated clinics and regarded as the most valuable but underutilized assessment in medicine. PNOĒ changed that

Outerport

Building out new LNG plants, HVAC systems, or semiconductor processes rely on hundreds of iterations of feasibility testing (through simulation or real-world lab tests) where different designs (combinations of equipment) and parameters are validated. The parameters are often locked in PDFs (datasheets, wiring diagrams, PFDs/P&IDs) which take thousands of hours to convert into CSVs / JSONs, and the simulators don't have an easy API to work with. Outerport bridges the gap by finding documents from

Caire Health

match 54

We believe that no emergency should have to wait. To make this a reality we build AI that instantly reads medical scans and enables critical care teams to make diagnoses better than radiologists. This saves lives by getting emergencies to treatment immediately and by discharging non-emergent patients quickly so the next emergency doesn’t have to wait either.
