Global platforms with EU/APAC volume (Adyen or Stripe Connect better); platforms wanting maximum vendor scale and capital base (Stripe Connect, Adyen, Finix fit); enterprise platforms (Worldpay or Finix better infrastructure depth).
US vertical SaaS platforms (30-500 employees) at the $5M-$50M GMV scale wanting modern PayFac-as-a-service with a focused vendor.
Why we say this
Editorial pulled these weaknesses from Rainforest’s product card in our Top 10 Embedded Payments Software for 2026:
- ! Smallest installed base in this ranking; $20M Series A 2023 capital base limited
- ! US-only geographic coverage
- ! Implementation timeline still being calibrated; PayFac onboarding remains non-trivial
- ! Sales motion still being established at upper-mid-market scale
- ! Brand recognition outside vertical-SaaS payments procurement limited
