In their own words
Cassandra
Cassandra is a web-based marketing measurement platform for teams deciding how to invest in growth. It combines marketing mix modeling with incrementality testing, including instant incrementality and performance incrementality reporting. Its models examine how paid media, organic activity, and offline or brand campaigns contribute to business outcomes. Teams can use budget scenario planning and forecasting before committing spend, as well as ROI reporting. Listed data sources include advertising platforms such as Google Ads, Meta Ads, and TikTok Ads, alongside commerce, email, and CRM services including Shopify, Klaviyo, and Salesforce. Scheduled files can bring in data from sources without an API, and custom connectors can be built for a model. Essentials starts at €2,700/mo and includes up to three MMM models and five incrementality experiments per year; it has a six-month minimum commitment. Complete and Scale also require six months, while Enterprise pricing is custom. A 14-day trial is available without a credit card. Cassandra is based in Milan and says it achieved SOC 2 compliance in 2024.
Keen
Keen is an AI-native marketing operating system for measuring media spend, building weekly buying plans, and forecasting the likelihood of reaching business goals. Its approach uses Bayesian econometrics, informed priors, and pre-built response curves that Keen says update as data grows. The platform says it separates marketing lift from external macroeconomic shifts, measures ROI across brand and commerce, and can quantify long-term brand effects. Its plans connect measurement to revenue and profit goals and can account for seasonality, media costs, budget floors, and inventory limits. Forecasts include goal probabilities, revenue ranges, and risk analysis; Keen claims up to 95% accuracy. Access options include SaaS, an MCP and headless API, or a managed service. The API can bring benchmarks, priors, plans, and forecasts into existing tools and receive actual results to trigger replanning. Keen lists integrations with 275+ tools and partners, including HubSpot, AWS, Snowflake, Meta, Google, TikTok, and Shopify. Pricing is on request, and a 14-day trial is listed.
