RonanRx Inc. on the record

What they shipped

  • From its YC profile: RonanRX is a full-stack pharmaceutical company, starting with personalized peptides and GLP-1s. In our first 10 weeks, we went from having no pharmacy to being licensed in 33 states. Since launch, we’ve grown 50% week over week. We manufacture the medications ourselves, sell directly to patients, and eliminate the layers of middlemen that make prescription drugs more expensive. What makes this possible is AI. Traditional pharmaceutical companies are built to manufacture one drug for millions of people. (source)
  • Its own site describes it as: "Personalized GLP-1 care from RonanRx. A physician personalizes your dose and support for your body, not a one-size label. Doctor-reviewed. It starts as a simple text." (source)

Who is behind it

  • Lloyd Armbrust, Founder/CEO: 2x YC founder. 3 Exits. 6 Kids. Built a $50M manufacturing business. Now building RonanRX. We are the world's first full-stack pharmaceutical company for personalized peptides & GLP-1s. We manufacture and ship direct to patients, using AI to personalize treatment. This was impossible before AI. Licensed in 33 states; growing 50% WoW. (source)
  • Emily Colman, Founder: Co-Founder & COO at RonanRx, I deliver personalized, doctor-reviewed peptide and GLP-1 care that starts with a text. I am go-to-market operator with over a decade in healthcare sales, most recently at Eli Lilly, I support weight management solutions for hundreds of physicians and millions of patients.
