Co-founder of HNC Software (San Diego, UCSD-adjacent), whose 1992 Falcon
Fraud Manager — a neural-network system for real-time card-fraud scoring —
became, via FICO's 2002 acquisition of HNC, the seed of infrastructure FICO
itself states was used in approximately 65% of all credit card transactions
worldwide as of 2008. He matters to the vault because his commercial work is
the largest, least-credited destination found so far for 1980s connectionist
research that academia had largely written off — a fact the vault has now
confirmed at Tier 1 rests entirely on FICO's own disclosures, not on any
recognition of Hecht-Nielsen's or HNC's role.

- 2026-08-02: HNC's own founding 1992 Falcon patent (US 5,819,226) cites
  Hecht-Nielsen's own 1992 book chapter, "Theory of the Backpropagation
  Neural Network," as background for the exact technique the patent
  commercializes — his name sits one citation beneath the company he
  co-founded ([[claim-us-patent-5819226-is-falcon-fraud-managers-founding-patent]]).
  The same patent independently confirms the architecture the vault had
  only inferred about his company's product: feedforward, trained by
  supervised backpropagation, multilayer
  ([[claim-hnc-1992-falcon-patent-names-network-architecture-as-feed-forward]],
