As answered by people managing FullStackToolkit and Kasumi.
Kasumi's answer:
Built-in offer marketplace where affiliates can discover offers ranked by real cross-affiliate earnings. Flat $9.99/month pricing with no per-event metering or feature tiers. Everything is included from day one. Real-time conversion pipeline visibility shows earned, pending, and paid conversions automatically. No other affiliate tracker has the marketplace built in.
Kasumi's answer:
Cost. Competitors charge per event, which scales fast with volume. Kasumi is flat rate. One customer moved from event-based billing and saw a 90% cost reduction. You get full features without upgrades. Setup is fast. Postbacks take minutes, not days. The marketplace alone saves time and brings in new affiliates.
Kasumi's answer:
Built for performance teams frustrated with expensive, bloated affiliate trackers. Kasumi strips out the excess and delivers core tracking functionality. Clicks, postbacks, attribution, reporting, fraud filtering. All at a price that makes sense. The built-in offer marketplace came from seeing affiliates waste time finding good offers.
Kasumi's answer:
Performance marketers, media buyers, and affiliate managers running campaigns at scale. Networks and affiliate managers managing multiple offers and partners. Anyone tracking conversions who wants predictable costs instead of surprise overages from per-event billing.
Kasumi's answer:
