Symbiosis

Close, long-term interaction between different species (or entities) taking three forms: mutualistic (both benefit), commensal (one benefits, the other is unaffected), or parasitic (one benefits at the other's expense). In business, every partnership, vendor relationship, and platform-developer relationship is a form of symbiosis. The critical question is which type: are both parties genuinely benefiting, or is one extracting value while the other declines? Relationships often start mutualistic and drift toward parasitism as power dynamics shift.

When to use it

When evaluating partnerships, vendor relationships, or platform dependencies; when a relationship that used to be beneficial starts feeling extractive; when designing business relationships to ensure mutual benefit is sustained; when analyzing ecosystem dynamics in your market.

How it can help

Map your key relationships using the symbiosis taxonomy. For each vendor, partner, or platform you depend on: is this mutualistic (genuine mutual benefit), commensal (they benefit, we're neutral), or parasitic (they benefit at our expense)? The most dangerous trajectory is mutualism-to-parasitism—when a platform that initially helped your business begins extracting more value than it provides. Early detection of this shift allows renegotiation or exit before dependency becomes too deep.
