The Harness Is the New Battleground

Read original

The harness, the software wrapping the model, is becoming the strategic asset. It decides what data flows in, what gets logged, & what gets used to train the next model.

Key takeaways

  • Model weights are commoditizing; the harness (data pipeline, logging, feedback loops) is the new moat
  • Control over data ingestion and training data curation determines competitive advantage in AI products
  • Implications for GTM: buyers should evaluate harness quality (observability, data governance, feedback loops) not just model performance

Why this matters for operators: Enterprise software buyers, AI platform evaluators, and GTM leaders assessing where defensibility actually lives in AI stacks

I cover AI×GTM intelligence like this every Wednesday.

Humans will keep inventing new reasons why we must stay in the loop with agents

  • Human resistance to full AI autonomy is not purely technical—it's psychological and organizational; companies will rationalize keeping humans in decision loops even when agents are capable
  • The 'human-in-the-loop' requirement may become a self-perpetuating narrative rather than a genuine necessity, driven by organizational risk aversion and change resistance
  • Product leaders at scale (Notion) are observing this pattern, suggesting it's a widespread phenomenon across enterprise AI adoption, not isolated to specific use cases

Comp plans for consumption pricing

  • Consumption pricing fundamentally breaks traditional SaaS comp models—requires rethinking sales incentive structures around usage vs. contract value
  • Four distinct contract structures exist (pay-as-you-go, uncommitted, committed, hybrid), each requiring different compensation mechanics and sales behaviors
  • Enterprise consumption-based deals create tension: customers want flexibility, sales teams need predictability for quota attainment—comp design must bridge this gap

3 revenue motions your AI is only half wired into

  • Model parity has arrived: OpenAI/Claude now trade evenly on core tasks, making 'better AI' a non-differentiator—the edge shifts to integration depth into existing revenue motions
  • Waste is quantified: teams paying $17K-$37K/month for AI seats that never touch pipeline generation; real cost is opportunity cost of unused capacity, not subscription fees
  • Lean teams have a structural advantage: cannot out-buy larger competitors on model access, but can out-embed them by wiring AI 1 revenue motion deep (pipeline → content → deals) with proprietary deal context competitors haven't seen
