Conway's Law and Cross-Hatching

· startups · Source ↗

TLDR

  • Org structure and culture propagate directly into product architecture; deliberately cross-hatching teams with opposing mandates converts external friction into internal alignment pressure.

Key Takeaways

  • Palantir’s FDE/SWE split is a canonical cross-hatching example: FDEs own one customer across the whole product, SWEs own one product area across all customers.
  • Tension between the two orgs was intentional, not accidental – it forced customer pain inside the org and aligned everyone around outcomes.
  • Separate people leads and project leads (with counter-weighted mandates) decoupled mentorship from management and let leadership grow independently of headcount management.
  • At Spiral, the seam between open-source Vortex and proprietary Spiral reproduces the FDE/SWE problem: features ship in Vortex but lag in deployment, or workarounds land in Spiral instead of being fixed upstream.
  • AI tooling shifts the bottleneck from code output to consensus, design, and taste; optimal pod size shrinks to 3-4, raising demands on structural scaffolding around those pods.
