What are “Fit Rules” and why do they save founders months?

“Fit Rules” are the non-negotiables a target must meet to qualify. Paired with “Kill Criteria,” they stop you from chasing deals that look exciting but will break your platform during integration.

Fit Rules checklist (example categories):

  • Target type: competitor / channel / adjacency
  • Customer profile match (who they sell to)
  • Margin quality (how profit is produced)
  • Key-person risk (where knowledge lives)
  • Systems complexity (integration effort)
