Episode 7: Photon Therapeutics — Overtaking Antibiotics in the Fight Against Infection, with Dr Mark Leddy

Enterprise Nation

What if a beam of safe UVC light could do the job of antibiotics for infections?

In this episode of The 99% Club – The Small Business Podcast, Enterprise Nation’s Aaron Asadi talks with Dr Mark Leddy, CEO of Photon Therapeutics, about a handheld UVC device designed to treat eye infections without accelerating antimicrobial resistance.

Mark explains how a precise UVC wavelength disrupts bacteria, fungi and viruses at the corneal surface, why bugs develop resistance to antibiotics and even share resistance genes with other bugs, and how a startup with limited resources is rolling out devices to veterinary ophthalmology first while preparing the path to human clinical use.

Inside the episode:

  • Why antibiotic resistance is rising and why “reserve” drugs are not the long term answer
  • How targeted UVC can reduce or replace antibiotics in eye infections and why eyes are the ideal first use case
  • Early real world results from veterinary clinics across multiple continents
  • Recruiting A-players in a resource-constrained startup and shipping before “perfect”
  • The surprising regulatory route that lets a tiny team get to market and iterate fast
