The largest and most established fintech category, covering merchant-acquiring processors, ISOs, and payment facilitators. Scaled processors (Fiserv, FIS, Global Payments) sit alongside modern platforms (Stripe, Block/Square, Adyen, Toast) that bundle payments into vertical software. Revenue scales with payment volume and the shift to digital spending. The defining trend, integrated payments embedded in industry software, has reshaped distribution and driven heavy M&A.

Characteristics

  • Scale-driven: payroll is only 17% of revenue, so the cost base is assets, not headcount
  • Moderate strategic-buyer pool: 87 firms exceed 500 employees, so a scaled asset has buyers, but not many
  • Largest, most established fintech category.
  • Integrated payments (payments in vertical software) is the key trend.
  • Revenue scales with digital and card-based spending.
