Medford residents in need of a little extra cash might not have to head to the blood bank anymore. Instead of sitting in a cold room that smells of rubbing alcohol for an hour while a nurse pumps the plasma out of your arm, you could be getting paid for something that leaves your body naturally – your poop.

Openbiome, a Medford-based company, pays donors $40 for every stool donation, plus an extra $50 if they donate five days a week. That equals to $250 a week, or $13,000 a year. But with any good thing, there is a catch. Openbiome will only pay you for your poo if you pass a rigorous medical questionnaire, stool and blood test. When it comes to poop, they only want the best of the best.

The company isn't collecting feces just for the fun of it; Openbiome aims to make fecal transplant treatments more accessible to those who need them. Openbiome is the country's first public stool bank and grew to work with 150 hospitals within their first year of collection.

The only problem: he couldn't find anyone to treat him.

"In the end, he treated himself at home, using his roommate's stool, a blender, and a glorified turkey baster," Smith and Burgess wrote on Indiegogo.

Without enough approved donors out there or enough trained staff screening the poo, fecal transplants are hard to find. And that's where Openbiome comes in. The company hopes to provide enough stool to hospitals across the country that anyone who needs a transplant can access one within a two hour drive from their home.
