Infrastructure Lock-In and Switching Costs
A hospital that runs Passepartout with HIPAA gate rules ($50K/yr) for five years has accumulated:
- A fact store with a decade of compliance decisions
- A proof forest of verified rules
- An empirical decision history tied to their specific deployment
- Customized gate rules encoding their specific workflows and approvals
Switching to a competitor means discarding all of it. The accumulated value grows as the fact store deepens. Annual revenue per enterprise grows from $250K in year one to $500K-$1M by year five as more domain packages are added.
This is the strongest residual moat. The evaluation harness (regression suite) is a close second — it grows with every deployment and cannot be ingested from public data. The verification monopoly and upgrade lifecycle compound this lock-in: every new regulation encoded as a gate rule deepens the proof forest, making the deployment harder to reproduce elsewhere.
