In this pitch, the presenter explains Tolka AI Therapeutics' approach to combating antibiotic‑resistant "superbug" infections using precision medicine powered by artificial intelligence. The core problem is that superbugs are a growing global health threat, and existing antibiotics are ineffective. Bacteriophages (phages) offer a solution because they can target specific bacterial strains without harming the human microbiome or host cells. However, their extreme specificity means a unique phage cocktail must be created for each patient. Tolka addresses this by integrating three recent technological advances: inexpensive genetic sequencing to rapidly identify the infecting bacteria, lab automation to replace labor‑intensive phage isolation and testing, and machine‑learning models to automate the decision‑making process for selecting effective phages. This combined AI‑enabled pipeline aims to produce personalized phage therapies at scale, making precision antimicrobial treatment feasible. The presenter also notes that the Q&A with judges felt like a constructive dialogue.

Chapters

We make precision medicine against superbug infections powered by AI. Superbugs, or bacteria that are resistant to all known antibiotics, are a large and growing threat. The great thing about phages is they are incredibly specific. They only kill the bacteria you want to kill and leave the microbiome and human cells completely intact. The bad thing about bacteriophages is they are incredibly specific. Which means you have to make a personalized drug for each and every person. So we're combining the newly available cheap genetic sequencing with lab automation, which replaces the human labor that used to be a big part of personalized phage therapy. And we combine it with machine learning to replace the human decisions that are also a big part of phage therapy. I felt the questioning went really well, honestly. I felt like it was a dialogue between me and the judges.
