Thousands of physicians and veterinarians, every day - from a solo vet in a small town to the largest hospital network in Brazil.
Queixa principal chief complaint

Doctors spend a third of their day typing into software instead of looking at their patients.

Conduta treatment

Delete the keyboard. Since 2014, my co-founder Gustavo and I have been building Doutore: three products for Brazilian healthcare, including an AI scribe that writes the medical record while the doctor looks at the human in front of them.

The whole thing started with a broken tooth - really.

no business model, on purpose

This one is not a Doutore product - I built it myself, at home, during our own long journey toward parenthood. It's an AI platform that analyzes almost a hundred fertility factors - exams, health history, lifestyle, medication - and turns them into insights a couple can actually discuss with their doctor. It helped us see our own path more clearly, so I opened it, free, to couples walking the same road.

It's not for making money. It's for making humans.
