Endotherm
An organism that generates body heat internally through metabolic processes, maintaining a relatively constant body temperature regardless of external conditions. Birds and mammals are endotherms.

Biological Context
Endothermy requires high metabolic rates and food consumption but enables activity in cold environments and sustained high-energy activities. Endotherms can forage, hunt, and reproduce across wider temperature ranges than ectotherms.
Business Application
Endothermic organizations: those with high internal energy (capital, talent, culture) that can operate regardless of market conditions. High burn rate but sustained capability.
