Mental Model: Zeroth Principles
Before solving "construction monitoring," question the axioms:
Axiom 1: "Construction progress requires human judgment"
Challenge: Progress against architectural plans is objectively measurable. Did the wall reach 10 feet? Is the rebar placed correctly? These are computer vision problems, not subjective assessments.
Axiom 2: "Contractors can't be held accountable"
Challenge: They can't be held accountable because there's no objective record. An immutable, timestamped visual record changes everything.
Identified Gaps
No consumer-grade solution — Enterprise tools exist; nothing for the homeowner building their first house
No automated progress detection — Current tools require manual entry
No milestone-to-payment automation — Progress verification isn't connected to payment release
No material verification — No way to confirm the cement bags on site match invoices
No historical contractor scoring — No reputation system based on verified data
Mental Model: Incentive Mapping
Who profits from opacity?
- Contractors: Benefit from ambiguity in scope, materials, timelines
- Material suppliers: Can substitute lower-grade materials
- Middlemen/relatives: Earn commissions on inflated bills
Who loses?
- Homeowners: Pay more, get less
- Banks: Release funds for incomplete work
- Good contractors: Can't differentiate from bad ones
Insight: The players who benefit from transparency (homeowners, banks, good contractors) outnumber those who profit from opacity—but they're not organized.
