Summary & changes
Sponsor banking links distinct creditors, issuers, technology providers and asset buyers. New product-level evidence clarifies those roles, alongside Parafin’s proposed Stripe transaction and the limits of announced embedded-banking adoption.
Version note: Added product-specific Lead, WebBank, Celtic, Column and Cross River roles; Parafin’s September 30 proposed acquisition and cumulative funding measures; and the announced Q4 Core Bank/Tekion rollout and Lead’s illustrative agent controls. Older evidence is dated explicitly; existing economics, regulatory context and historical revisions are retained. Checked October 4, 2026 UTC.
