Opportunity signals

  • Water rates in many US metros have risen faster than inflation, making bill anxiety a recurring search trigger.
  • Most utility portals show usage but do not explain it — a gap for plain-language diagnosis tools.
  • Hardware monitors cost $100+; software-only analysis has a much lower trial barrier.

Risks & pain points

Free-alternative gravityHIGH

Utilities and extension services publish free conservation guidance, capping willingness to pay.

Seasonal demandMED

Bill-shock searches spike in summer; retention through low-usage months is unproven.
