Payments Strategy Breakdown by Dwayne Gefferie

Payments Strategy Breakdown is a Substack by Dwayne Gefferie that analyses where the payments industry is heading and what that means for companies building in it.

Recurring themes Recent posts look at legacy processors such as Fiserv, Worldline and TSYS using AI to modernise their platforms, Stripe's position among AI merchants and in B2B payments, PayPal's unbundling strategy, and the comeback of US debit networks. Other pieces cover digital goods, prediction markets and cross-border payments, plus deep dives into agentic commerce frameworks and growth strategies of fast-growing fintechs.

Structure The archive is organised into Strategy Breakdowns, technical frameworks and rails discussions, and shorter Notes, with an about page for the author. Posts from July through October 2026 are visible, with likes and comments under featured articles.

Why payments people read it It is a strategist's view rather than news: who is gaining share, which rails are being rebuilt and why. PSP and acquirer product leads can test their roadmap against it, while merchants with digital-goods or marketplace models can see how providers may reposition. Posts are in English.
