Type: SaaS | Level: Hard | Category: Finance, Marketing Analytics
A platform for marketing and finance teams to build, compare, and maintain multi-touch attribution models. Connects ad platform, CRM, and product data to compute revenue attribution across channels using configurable models.
Unique niche feature: Implements a "model disagreement detector" that compares first-touch, last-touch, linear, and data-driven attribution outputs for the same cohort and surfaces channels whose ROI assessment changes most dramatically depending on the model chosen, highlighting where model selection risk is highest.
Monetization: Per monthly attributed revenue tracked. Data team subscription with model versioning.
