B4 Index · vendor files
The vendor files
11,031 vendor files, drawn from the 20,925 vendors the index tracks. Each file covers what the product is, which categories it serves, funding history, and when the index last verified it alive. Whether to buy any of them — or build instead — is the category question, and the verdict lives in a B4 subscription.
