Ecosystem Engineering
Without their platforms, the ecosystems they enable couldn't exist.
Some species create physical structures that many other species depend on. These ecosystem engineers or keystone engineers have disproportionate impact because their physical modifications create habitat, resources, or environmental conditions that wouldn't otherwise exist. Keystone engineers create resource heterogeneity - spatial variation in habitat, light, water, nutrients, or temperature that allows more species to coexist. Homogeneous environments support few species; heterogeneous environments support many.
Business Application of Ecosystem Engineering
ARM, TSMC, and SQLite are organizational ecosystem engineers - they create the technical infrastructure (instruction sets, manufacturing processes, database standards) that thousands of other companies build on. Without their platforms, the ecosystems they enable couldn't exist.
