A-to-F safety grade for vetting contractors before you hire

Homeowners cannot easily judge whether a contractor is licensed, insured, and free of serious complaints, so they hire on gut feel and risk unsafe or unfinished work.

Electric code calculator

Electricians constantly perform NEC calculations (conduit fill per Chapter 9, ampacity/wire sizing per Table 310.16, voltage drop, box fill per Article 314.16, and load calcs) by flipping through dense, frequently revised code books or generic calculators. The NEC changes every three years and the 2023 edition added nine new articles, deleted three, and revised many titles, so a manual or outdated reference produces errors that cause failed inspections, rework, callbacks, and liability. Existing free web calculators are fragmented across single-purpose pages and lack offline reliability, current-code traceability, and project save/sharing.

Validation criteria

Same rubric, side by side.

Bars use the existing report visual scale, with each criterion scored out of 10.

Demand signal

A-to-F safety grade for vetting contractors before you hire 4.6/10

Demand looks weak because the report has 2 source-backed signal(s), an editorial confidence of 42/100, and a defined buyer in Home-improvement contractor vetting.

Electric code calculator 6/10

Demand looks thin because the report has 4 source-backed signal(s), an editorial confidence of 58/100, and a defined buyer in Electrical trades software and field-reference tools serving residential, commercial, and industrial electrical contractors in the US (and Canada via CEC)..

Problem severity

A-to-F safety grade for vetting contractors before you hire 5/10

Problem severity is weak when the buyer pain, customer value, and dream-outcome scores are combined.

Problem severity is thin when the buyer pain, customer value, and dream-outcome scores are combined.

Willingness to pay

A-to-F safety grade for vetting contractors before you hire 4.5/10

Willingness to pay is weak; the model has a monetization hypothesis, but it must still be proven through paid pilots or explicit pricing objections.

Willingness to pay is weak; the model has a monetization hypothesis, but it must still be proven through paid pilots or explicit pricing objections.

Competitive saturation

A-to-F safety grade for vetting contractors before you hire 4.8/10

Competitive room is reduced by 2 recorded alternative(s); the wedge must stay narrow and differentiated.

Electric code calculator 3.9/10

Competitive room is reduced by 3 recorded alternative(s); the wedge must stay narrow and differentiated.

Feasibility

A-to-F safety grade for vetting contractors before you hire 4/10

Feasibility is weak for a high build if the MVP is limited to the first measurable workflow.

Electric code calculator 6.2/10

Feasibility is thin for a moderate build if the MVP is limited to the first measurable workflow.

Revenue and GTM

A-to-F safety grade for vetting contractors before you hire

Revenue: $250K-$2M ARR potential if the wedge proves budget urgency and becomes a recurring workflow.

GTM: Start with manual concierge output, direct outreach, and community proof before paid acquisition.

Execution: Execution is high; the main constraint is staying narrow enough for a first proof loop.
