Cassandra

What Cassandra does for Shopify brands

• ●Incrementality testing separates channels driving new sales from ones taking credit
• ●Cut spend on zero-incrementality channels, reinvest in high-return ones
• ●Automated mmm replaces manual attribution modeling & channel reporting
• ●Geo-experiment design built in, no analyst required to set up tests

Overview

Cassandra is an AI marketing platform for growth teams that combines marketing mix modeling and incrementality tests to measure what drives sales. It then carries out budget moves, ad launches, creative and reporting in the brand's ad accounts, within rules the brand sets. It connects to Shopify and other ad, CRM and analytics sources.

For Shopify brands

• ●Connects Shopify sales data with ad platform spend in one dataset, by campaign and by day.
• ●Moves budgets, launches and pauses ads and writes reports in ad accounts, with approval steps the brand chooses.
• ●Measures each channel's contribution with marketing mix models and geo incrementality tests to guide budget allocation and forecasts.

How it works

The brand adds its website, connects its data and receives a growth plan, then approves actions that Cassandra carries out within the brand's limits. Cassandra compares results with the plan seven days later. The Guided plan includes a six-week onboarding with a Cassandra marketer.
