Best thing to validate

If fabricators adopt it, a lightweight directory could become the go-to search t

Biggest risk

Suppliers may not share real-time inventory, and fabricators may find manual cal

Critical assumption (summary)

Fabricators need real-time inventory across multiple suppliers and would use a web tool for this.

Show objections and continue/stop

Strongest objection

Suppliers won't share real-time data; fabricators already have relationships with a few suppliers.

Continue if

If interviews show fabricators rely on a single supplier, pivot to supplier-side tool.

Pivot if

If no signups and interviews show manual process is fine, stop.

Show score rationale

The keyword suggests a market need, but it's unproven,A directory model might work

Fill the critical gaps (max 2)

“I don’t know” is fine — we give how to get evidence; we never invent interviews or payments.

Q: Do fabricators currently find slab availability a significant pain point?

Determines if there is a real need.

How to get evidence: Conduct 5-10 interviews with US fabricators asking about their current process, time spent, and frustrations.

Q: Will suppliers provide or allow access to their inventory data?

Real-time data is the core value; without it, the product fails.

How to get evidence: Reach out to 3-5 slab suppliers and ask if they would share inventory feeds or allow scraping.

How should I read the score?

Current OPC feasibility score is 5/100. It is an AI-assisted executability check, not a market guarantee. Low scores mean “prove demand first,” not “never build.”

07 Evidence & boundaries

Demand evidence summary

No external evidence; demand is a hypothesis based on the pain of manual search.

External record

None

User-stated

None

Model hypothesis

  • Fabricators currently waste time calling suppliers to check slab availability
  • Suppliers have inconsistent online inventory listings
  • A real-time aggregator would save time and reduce project delays

Known facts

  • Natural stone slabs are heavy and typically sold by suppliers in yards
  • Fabricators need specific dimensions and colors
  • Suppliers have varying inventory

Unverified assumptions

  • Fabricators find it hard to locate slabs
  • Real-time data is feasible to obtain
  • There is a willingness to pay
