Supply chain visibility should not require weeks of email chains.

Sourcing engineers and procurement managers waste days chasing supplier responses, validating certifications, and mapping Tier 2 and 3 relationships. TierWire eliminates that friction by compiling verified capability profiles from public records.

No self-reporting. No surveys. No delays. Just structured data on every automotive supplier that matters.

How TierWire Works

1

Identify Suppliers

We map the complete active roster of Tier 1, 2, and 3 automotive suppliers across North America, EMEA, and Asia. Updated continuously as new OEM relationships are disclosed and supplier registrations change.

2

Compile Public Records

We aggregate data from SEC filings, certification databases, patent registries, regulatory filings, trade databases, and published OEM supplier lists. One structured profile per supplier with sourcing-grade accuracy.

3

Structure and Deliver

Capability profiles are normalized, cross-referenced, and updated in real time. Search by capability, location, OEM relationship, or USMCA eligibility. Export as CSV for integration into your procurement workflow.

What Makes TierWire Different

✓ No Self-Reporting

Suppliers don't fill out forms. We compile profiles from disclosed public records. No incentive to inflate capabilities or hide risks. Data reflects reality, not marketing.

✓ Continuous Updates

Public records change. OEM relationships shift. Patent filings arrive. We update profiles in real time. Your intelligence is never stale.

✓ Sourcing Grade Accuracy

Every profile is verified against multiple sources. OEM relationships cross-referenced. Certifications confirmed. Locations validated. Built for procurement teams.

✓ Structured Data

Not unstructured web results. Standardized profiles with indexed capabilities, compliance flags, USMCA eligibility, patent trends, and OEM relationship data ready for search and export.

Built by Supply Chain Practitioners

TierWire was founded by automotive supply chain engineers and sourcing managers who spent years chasing incomplete supplier intelligence. Every RFQ process began with hours of manual research. Tier 2 and 3 visibility required calling OEM account managers. Compliance tracking meant spreadsheets that fell out of sync within weeks.

We built TierWire to solve what we experienced firsthand. Public records exist. OEM relationships are disclosed. Certifications are verifiable. Patents are published. The data should work for procurement teams, not against them.

Today, TierWire is used by sourcing teams at OEMs and Tier 1 suppliers across North America to move faster, source smarter, and see risks before they become supply chain crises.
