The mission at OpenBiome is to provide a product that cures C Diff at a rate of 85% or higher. It is great to work there since you are helping to dramatically improve and in many cases, save lives.
Inconvénients
The other side of the mission, to research the microbiome to learn what other diseases can be helped or cured. This work has not really taken off yet and it is important to keep the organization alive going forward.
