Precision UTI Diagnostics · San Francisco Bay Area

The Exact Pathogen.
In Minutes.
Not Days.

Berron Diagnostics is building a siderophore-detecting biosensor and AI platform that identifies the bacterial cause of a UTI from a small urine sample — enabling precise, targeted treatment at the point of care.

The Problem

A broken diagnostic workflow
is fueling a global crisis.

When a woman walks into an urgent care clinic with a UTI, her doctor has no way to identify the exact pathogen at the point of care. The result is a cascade of consequences that harms patients and accelerates antibiotic resistance worldwide.

💊

Blind Prescribing

Physicians prescribe broad-spectrum antibiotics without knowing the specific pathogen or its resistance profile.

⏱

Dangerous Delays

Lab cultures take 48–72 hours. Patients are mid-treatment with the wrong antibiotic before results arrive.

🔄

Recurrent Infections

60% of women experience at least one UTI in their lifetime. Misdiagnosis drives recurrence and worsens outcomes.

🌍

AMR Crisis

Antibiotic overuse accelerates antimicrobial resistance — a silent pandemic killing 700,000+ annually. UTIs are a leading driver.

Our Solution

Stop Guessing.
Start Treating.

The Trojan AI Platform detects siderophores — unique chemical signatures secreted by UTI pathogens — directly from urine, mapping each molecular fingerprint to the exact bacterial species and resistance profile in under 15 minutes.

Our Mission

Built around a personal cause.
Scaled for global impact.

🔬

Science-First

Every product decision is grounded in validated biochemistry — two years of original siderophore research before a single line of code was written.

👩‍⚕️

Women's Health

UTIs disproportionately affect women. We are building the diagnostic tool that the most underserved patient population deserves — fast, accurate, and accessible.

🛡

AMR Defense

Every precise diagnosis we enable is one fewer unnecessary broad-spectrum antibiotic — building infrastructure for a post-AMR world.

The Science

Siderophores: The Chemical Fingerprint That Betrays Every Pathogen

Siderophores are small, high-affinity iron-chelating molecules secreted by bacteria to scavenge iron — a critical survival mechanism. Every bacterial species produces a structurally unique siderophore signature, making them an ideal and previously untapped diagnostic target.

Key Insight

Siderophores appear in urine at detectable trace levels without any amplification step — enabling direct, rapid point-of-care detection. Unlike DNA-based PCR tests, no laboratory infrastructure is required. Each pathogen's siderophore profile also encodes its iron-acquisition strategy, correlating with virulence and antibiotic resistance.

UTI-Relevant Targets

Known Siderophore Fingerprints

Klebsiella pneumoniae
Siderophore: Enterobactin + Aerobactin
Primary UTI + sepsis pathogen — our lead research target. Subject of the founder's 2-year bioinformatics study, pending publication in JPBA.
Escherichia coli
Siderophore: Enterobactin + Salmochelin
Causes approximately 80% of all UTIs globally. The primary commercial focus of the Berron platform at launch.
Pseudomonas aeruginosa
Siderophore: Pyoverdine + Pyochelin
Highly antibiotic-resistant; studied alongside Klebsiella by the founder. Critical in hospital-acquired and recurrent UTI cases.
Staphylococcus saprophyticus
Siderophore: Staphyloferrin A & B
The second most common UTI pathogen in young women — a key demographic in our target patient population.
The Trojan AI Platform

How It Works

01

Urine Sample

Micro-volume urine collected at point of care. No lab send-out, no centrifuge, no delay.

02

Biosensor Detection

Electrochemical biosensor directly captures the siderophore iron-chelating molecules excreted by the pathogen.

03

AI Mapping

Trojan AI maps the siderophore chemical fingerprint to the exact bacterial species and antibiotic resistance profile.

04

Clinical Insight

Physician receives the exact pathogen ID and a targeted antibiotic recommendation in under 15 minutes.
