Example
Market sizing for a developer productivity tool. Top-down: $12B global developer tools market, $3.2B SAM in code review and testing. Bottom-up: 400K target companies x 12% adoption rate x $24K ACV = $1.15B SOM. Sensitivity shows SOM ranges from $800M to $1.6B depending on ACV assumption. Both methods converge within 20%.
