Your suppliers have suppliers you've never seen.

Apvyne maps the tier-2 and tier-3 concentration risks buried in your bill of materials—before a single-source bottleneck becomes a production shutdown.

The blind spot

The risk hiding below your Tier-1 contracts

Standard supplier qualification covers the vendors you pay directly. But when four of your contract manufacturers all source from the same PCB component supplier—and none of them mention it—your BOM carries a concentration risk no contract language protects against.

Sub-tier BOM Mapping

Trace every line item in your bill of materials through two and three supplier tiers. Identify single-source nodes before they become bottlenecks.

Concentration Risk Scoring

Each supplier cluster gets a concentration score based on cross-customer dependency, geographic overlap, and financial health signals.

Spend + Risk Overlay

Know which of your highest-spend supplier paths carry the most sub-tier concentration—prioritize where due diligence actually matters.

From BOM data to board-ready risk view

01

Connect your data

Bring your ERP spend data, supplier master, and BOM files. Apvyne maps the structure.

02

We trace the network

Apvyne maps each component in your BOM through two and three supplier tiers, identifying shared sub-tier nodes, single-source dependencies, and geographic concentration clusters—none of which appear in standard Tier-1 SRM data.

03

Act on what you find

Prioritize high-concentration spend paths, model diversification scenarios using your actual spend cube, and export board-ready risk reports that speak in financial exposure terms—not just supplier count.

We'd done a thorough Tier-1 supplier review before our annual board risk briefing. Apvyne ran the BOM against our sub-tier graph and surfaced twelve concentration paths we hadn't seen—four of them traced back to the same PCB laminate supplier. That wasn't in any scorecard.

We were qualifying a new contract manufacturer through a standard RFP process. Apvyne mapped the winner's sub-tier network before we awarded the contract—and found they shared two critical component suppliers with three of our existing CMs. That's a sole-source risk we would have missed entirely.
