In the era of AI-Driven Development, scaling means bureaucracy. NASDAQ's top ten companies operate on 12-hour planning cycles, not 3-month ones.

AIDD, MobAI, FAST and XSCALE focus on the real bottleneck in modern businesses – the flow of learning within and between teams, streams, and markets. If your business can't accelerate that, AI will eat you alive and spit out the bones.
