  Banyan is a privacy-first, item-level receipt data infrastructure platform that
  acts as middleware between merchants, banks, fintechs, and merchant service
  providers so they can securely share and enrich transaction data without
  bilateral contracts. Merchants send receipt and item detail to Banyan (via
  REST API or batch), and financial institutions submit card transactions to be
  matched and enriched with SKU-level line items, powering products like
  card-linked offers (CLO), expense management, and receipt display inside
  banking apps. Banyan has processed over 21 billion receipts across a network of
  40,000+ merchant stores and 5,000+ financial institutions. Founded in 2013,
  backed by Battery Ventures, Fin Capital, M13, TTV Capital and others, and
  acquired by Bilt Rewards in March 2025. The public developer platform at
  developers.banyan.com exposes an OAuth2 REST API (api.banyan.com/rest/v1) plus
  a webhook egress surface for enriched transactions and offer redemptions.
