ShareASale, part of Awin, hosts 21 000+ merchants with a strong base of lifestyle and review‑site publishers. It is valued for low monthly fees, simple UI, and rapid onboarding—ideal for DTC brands and niche e‑commerce stores.
Uppercut.co, in contrast, optimises for few‑but‑high‑value SaaS deals, screening affiliates for domain expertise instead of open enrollment. While ShareASale offers a legacy XML feed, Uppercut exposes a modern REST API enabling deeper CRM and billing integrations for SaaS revenue teams. Stripe‑handled 30‑day payouts further boost cash flow compared with ShareASale’s NET‑60 schedule.
