Decompose anything
From LLMs to EVs — break products into upstream categories, materials, and tradeable inputs layer by layer.
supply chain intelligence
See what your product is really made of.
Vein traces any product or service down to raw, tradeable elements — surfacing hidden chokepoints, tickers, and upstream dependencies investors and operators miss.
Why Vein
Spot chokepoints
Surface concentration risk — single-source fabs, rare-earth refining, HBM packaging, and other bottlenecks.
Link to markets
Tickers and trend notes at each node, with optional validation against live market data sources.
Share & collaborate
Public trace links, workspaces, side-by-side compare, and portfolio overlap for teams.
