Mechanism
Commensalism
TL;DR
In commensal business relationships, one party benefits while the other is neutral.
Commensalism: One organism benefits, the other is unaffected. Barnacles attach to whales, getting transportation across oceans. The whale doesn't care.
Business Application of Commensalism
In commensal business relationships, one party benefits while the other is neutral. This is more common than true mutualism but less valuable. The risk is that commensal relationships can drift toward parasitism if the 'neutral' party starts bearing hidden costs.
