Companies should restructure around three archetypes — builder ICs, outcome-owning DRIs, and AI-founder leaders — eliminating human middleware because queryable, artifact-rich organizations let intelligence route information directly, making velocity a function of token usage not headcount.

No single model dominates; Anthropic wins coding (52% YC share), Gemini grows to 23% on reasoning/grounding, founders abstract model choice via eval-driven orchestration swapping models per task.

A new paradigm where humans write specifications and test harnesses while AI agents generate, test, and iterate code until passing — some YC companies already operate with zero hand-written code, achieving 1000x engineer leverage.

The critical shift is maximizing API token spend rather than hiring; one person with AI tools equals a pre-AI engineering team, so lean teams should run uncomfortably high API bills that are still far cheaper than equivalent headcount.
