Gutgutgoose on the record

What they shipped

  • From its YC profile: Most data companies pay for their data. Ours pays for itself. Customers send us a stool sample. We sequence it, build a metabolic model of that gut, and simulate whether each probiotic strain has an open niche it can colonize. We formulate the best candidates, then re-sequence 90 days later to see what actually took hold and what changed. Each cycle gives us the baseline gut, the intervention, and the outcome. At scale, the endgame is models that predict chronic disease years before symptoms. (source)
  • Its own site describes it as: "Personalized probiotics matched to your gut. Take a simple at-home test and get a personalized probiotic compounded just for you. 180-day money-back guarantee." (source)

Who is behind it

  • Anis Mihrshahi, Founder: Youngest Math Olympiad champion in Queensland history. USQ Chancellor's Excellence Scholarship (AI and Data Science). At GutGutGoose, I work operations behind the scenes and co-built the mechanistic algorithm behind our personalised probiotics. (source)
  • Leon Mojarrabi, Founder: started university at 14, spent four years at a yc tech unicorn, then launched a pharmacy that hit $4M in revenue to fund GutGutGoose; strain-level metabolic modelling of the gut to catch disease decades early. I'm unreasonably interested in your poop's data. (source)
  • 1 open role listed on its YC jobs page when the profile was read (2026-09-05). (source)
