Cassandra vs Triple Whale: an AI platform built for commerce, or an AI marketing brain for growth teams
Triple Whale describes an AI platform for modern commerce: its Moby agent can act in connected ad accounts, and Compass unifies attribution, MMM and GeoLift tests. Cassandra, an AI marketing brain, also does the work, deciding with a Bayesian MMM checked by geo experiments.
The difference is where decisions come from. Triple Whale says Moby works on first-party measurement, real-time business data and live benchmarks. Cassandra checks every move against its forecast.
What Cassandra is
An AI marketing brain for growth teams.
- Connects to the ad accounts, the store or CRM, and analytics.
- Measures what each channel, campaign and ad adds, with a Bayesian MMM checked by live geo experiments.
- Does the work: plans to the growth target, moves budgets, adjusts ads, makes new ads, writes reports.
- Your rules: the team decides what runs on its own and what waits for approval.
- Improves: every move is checked against its forecast; what worked shapes the next plan.

When Triple Whale is the better choice
Per Triple Whale's own pages:
- One ecommerce platform: data from every ecommerce and retail channel, with attribution, MMM, incrementality, creative tools and Moby.
- Daily attribution: seven attribution models, and multi-touch attribution powered by the Triple Pixel.
- Agent beside your analytics: Moby acts on Facebook Ads, Google Ads and more.
- Attribution, MMM and tests together: Compass, listed as an add-on, included on Enterprise; per Moby 2, an add-on to any plan.
What each one says it is
- Triple Whale: an AI platform for modern commerce that sees the business in real time and acts on the go-ahead.
- Moby, its AI agent, can act in connected ad accounts.
- Compass unifies attribution, MMM and incrementality; its homepage points to GeoLift tests to validate incremental impact.
- Cassandra: an AI marketing brain that measures with a Bayesian MMM checked by geo experiments, then does the work.
How each automates the ads
- Moby, Triple Whale's AI operator for ecommerce, can scale budgets, pause underperformers and launch campaigns.
- Automations run in two modes: Ask every time, or Let Moby decide.
- Approval: per Moby 2, most actions are queued for your approval before they run.
- Moby Media Buyer: the Moby 2 FAQ says it runs ad campaigns across Meta and Google today, with more platforms coming soon.
- Cassandra moves budgets, launches, pauses and adjusts ads, within the rules the team sets.
Where decisions come from, and how each learns
- Triple Whale says Moby sits on first-party measurement, real-time business data and live benchmarks from thousands of brands.
- On Enterprise, its pricing page says Moby orchestrates the loop between MMM, incrementality and live campaign data: "Every test sharpens the next budget allocation."
- Compass, per its Moby 2 page, is a closed loop that calibrates weekly.
- Cassandra decides from a Bayesian MMM checked by geo experiments, checks every move against its forecast, and plans from what worked.
How each measures: the model and geo tests
- Triple Whale's MMM: its own proprietary statistical model, with channel budget recommendations and spend simulations.
- Priors: its help center offers GeoLift experiments and pixel attribution as priors.
- GeoLift holdouts: regions are matched and a synthetic control estimates what would have happened without the change.
- Any channel with data in Triple Whale can be set up for a geo holdout, per Moby 2.
- Cassandra runs geo experiments beside its Bayesian model; each result checks that channel's figure.
What each publishes about pricing
- Tiers, as listed on 16 October 2026: Free, Foundation, Automate, Enterprise.
- Paid tiers: 12-month subscriptions, priced by annual GMV and package.
- Free plan: first and last click attribution; no credit card required, per its Moby page.
- Ad actions on paid media are listed from Automate.
- Compass: an add-on, included on Enterprise; Moby 2 says it is an add-on to any plan.
- Cassandra: start free with your website and data, or book a demo. Paid plans scale with yearly ad spend.
Questions to ask both vendors
- How is the model built? Method, assumptions, and how uncertainty is shown.
- Which channels were tested, and when?
- How does a test change the model? See one channel before and after.
- How would a channel that adds nothing show up?
- Which figures does the agent act on? See one budget change and its numbers.
- What does the tier with the model, tests and ad actions cost at your scale?
What our numbers need
- A channel needs enough spend history, and variation in that spend, before the model can read it.
- Geo experiments need regional structure: a single-market business with no comparison group cannot run one.
- Tests need a few weeks to return a readable result.
Cassandra learns what drives growth with a Bayesian marketing mix model checked by geo experiments, then does the work, within the rules you set. Start for free with your website and data, or book a demo.
What running both involves
- Label each report's scope: "share of tracked conversions" and "share of total revenue" stop looking contradictory.
- Split the questions: budget planning reads the model; journey reporting reads attribution.
- Give each agent a lane, so two agents never change the same campaigns.
How to choose
- Triple Whale: an ecommerce brand that wants one platform for data, attribution, creative, measurement and an AI agent.
- Cassandra: a growth team chasing a bigger target with the same people, working from a model checked by geo experiments.
- Both: keep daily commerce analytics and add Cassandra for the growth plan and the work that follows.
Questions
What is the difference between Cassandra and Triple Whale for marketing mix modeling?
Triple Whale describes an AI platform for modern commerce whose Compass unifies attribution, MMM and GeoLift incrementality tests. Cassandra, an AI marketing brain, measures with a Bayesian marketing mix model checked by live geo experiments, then does the work.
Does Triple Whale have a free plan?
Yes. Its pricing page lists a free plan with first and last click attribution, and its Moby page says no credit card is required. Compass is listed as an add-on, included on Enterprise; its Moby 2 page says it is an add-on to any plan.
Can Triple Whale's MMM use test results?
Yes. Its help center describes an option to include GeoLift experiments as priors in the model, and an option to fill priors from pixel attribution.
Does Triple Whale run geo experiments?
Yes. Its help center describes GeoLift holdout tests, and its Moby 2 page says any channel with data in Triple Whale can be set up for them.
What are alternatives to Triple Whale?
Other measurement platforms include Northbeam and Rockerbox. Cassandra, an AI marketing brain, is another option: it measures with a Bayesian marketing mix model checked by live geo experiments and does the work, within the team's rules.
Can Triple Whale's AI agent run my ads?
Yes, according to Triple Whale: Moby can scale budgets, pause underperformers and launch campaigns, after approval or within an automation's rules. Its Moby 2 FAQ says a Moby Media Buyer runs ad campaigns across Meta and Google today, with more platforms coming soon.
