Install-Base Moats

Install-base moats are strategic advantages that come from putting a platform in front of enough users and developers that ecosystem reach outweighs competing architectures’ theoretical elegance.

Key points

• Jensen argues that install base defines an architecture: developers choose platforms where their software can reach many people ^[src-065].
• NVIDIA put CUDA on GeForce even though it increased costs and pressured margins because GeForce’s consumer reach could seed the CUDA developer ecosystem ^[src-065].
• The source contrasts x86’s survival with the failure of more elegant RISC architectures to show that ecosystem reach can matter more than architectural beauty ^[src-065].
• In AI infrastructure, CUDA’s install-base moat compounds with tooling, education, university adoption, cloud deployment, and hardware breadth ^[src-065].
