Cassandra vs Smartly: enterprise creative and media automation, or an AI marketing brain that learns
Smartly describes itself as an AI advertising platform that automates creative production, campaign launches and budget allocation for enterprise marketers and agencies. Cassandra, an AI marketing brain, automates the ads too, and decides where to invest from a marketing mix model checked by geo experiments.
Both work with incrementality. Smartly says INCRMNTAL reads it always-on from natural changes in campaign activity; Cassandra builds the measurement into the brain, and what worked shapes the next plan.
What Cassandra is
Cassandra is an AI marketing brain for growth teams.
- Learns: a Bayesian marketing mix model checked by live geo experiments measures what each channel adds.
- Does the work: plans, budgets, ads, creative and reports, within the team's rules.
- Control: the team decides what waits for approval.
- Improves: every move is checked against its forecast.

When Smartly is the better choice
- Enterprise-scale creative. Smartly lists AI Studio, dynamic templates, Dynamic Product Ads and Dynamic Creative Optimization.
- Many campaigns at once. Smartly says teams can launch and manage hundreds of campaigns at once.
- Always-on incrementality. Smartly says INCRMNTAL reads it from natural fluctuations in campaign activity, instead of pausing campaigns.
- Have an MMM already? Smartly says Predictive Budget Allocation can take in a team's MMM and incrementality insights.
What each one says it is
- Smartly calls itself an AI advertising platform, organised in three suites: Creative, Media and Intelligence.
- Its homepage says "Smartly brings AI into every step of advertising".
- Its March and June 2026 press releases say it supports 800+ brands and manages over $7 billion in ad spend globally.
- Cassandra measures what each channel adds, then plans, moves budgets, manages ads and makes creative.
How each one automates the ads
- Smartly Media lets teams launch and manage hundreds of campaigns at once, from feeds and data sheets.
- Predictive Budget Allocation (PBA) shifts budget to top-performing campaigns and channels in real time.
- AI Studio generates and enhances images and video.
- Cassandra moves budgets, launches, pauses and adjusts ads, and makes new ads in the brand's style.
Both automate the ads. The difference is what each move is based on.
Where decisions come from
- Budget goals. Smartly's PBA page describes "integrating incremental and Marketing Mix Modeling (MMM) insights into PBA".
- INCRMNTAL. Smartly says INCRMNTAL's always-on signals inform optimisation inside Smartly.
- The deal. In a press release of 17 March 2026, Smartly announced a letter of intent to acquire INCRMNTAL.
- The FAQ on Smartly's INCRMNTAL page refers to INCRMNTAL as acquired by Smartly.
- Cassandra runs its own Bayesian marketing mix model, checked by live geo experiments, and checks every move against its forecast.
How each one learns over time
- Smartly says PBA learns from your data and adapts in real time.
- Its Synapse announcement describes a shared intelligence and memory layer that helps the system learn from every campaign.
- Cassandra checks every move against its forecast, and what worked shapes the next plan.
- Ask both what counts as a result, and how one result changes the next plan.
Control, approvals and access
- Smartly: Optimization Triggers run the rules a team sets up; the team chooses PBA's goals and multipliers.
- Smartly describes Producer as where teams collaborate to adapt, approve and launch ads.
- The Smartly pages we read invite buyers to chat with its team (as listed on 16 October 2026).
- Cassandra: the team decides what runs on its own and what waits for approval. Every change is recorded.
Questions to ask both vendors
- Where does each budget move come from?
- When a measurement result lands, what changes?
- How is incrementality measured and validated?
- Which actions run on their own, and which wait for approval?
- Can I export the numbers behind each decision?
- What are the plans and pricing for my spend?
Limits worth knowing
- Spend history. A channel needs enough spend history and variation to read.
- Regions. Geo experiments need regional structure.
- Time. Tests need a few weeks to return a readable result.
Cassandra automates the ads too, and its decisions come from a Bayesian marketing mix model checked by live geo experiments. Start for free with your website and data, or book a demo, and ask both vendors the questions above.
What moving between platforms involves
- Your history moves with you. Spend and outcomes by channel are what a marketing mix model learns from.
- Start side by side. Run both on one period and compare where each would move the next budget.
How to choose
- Smartly: enterprise-scale creative and media automation, with always-on incrementality signals from INCRMNTAL.
- Smartly: you want budget allocation to take in your MMM partner's insights, which Smartly says PBA can do.
- Cassandra: an AI marketing brain whose decisions come from a marketing mix model checked by live geo experiments.
