Agentic MMM in Action: The World’s First End-to-End Workflow for Ecommerce and Retail webinar is now available on demand.
In this 45-minute live session, we showed how Sellforte AI connects campaign measurement, budget simulation, and media execution into one unified workflow without switching tools.
You'll see how incrementality measurement tells you which campaigns actually drove sales, how scenario planning lets you model budget decisions before committing, and how budget recommendations execute directly in Google or Meta Ads with guardrails you control.
Below is the complete Q&A from the live session, covering how Sellforte handles incrementality measurement, cross-channel budget optimization, model accuracy, AI reliability, and the guardrails that keep outputs grounded in real data.
Meridian is a modeling library, whereas Sellforte provides an end-to-end workflow that connects measurement, optimization, and execution into an automated SaaS solution.
Unlike in-house MMM tools that focus mainly on reporting on quarterly/monthly basis, Sellforte operationalizes automated daily insights into concrete recommendations that can be activated in ad platforms.
Compared to in-house solutions, Sellforte reduces time-to-value, leverages built-in experiment-calibration, and removes the need for large dedicated data science teams while maintaining transparency and control.

Yes. Recommendations are based on marginal incremental ROAS across all included channels. The optimizer continuously reallocates budget to balance marginal returns, ensuring investment flows to the highest-performing opportunities.
The user can create “planning groups” where the system only optimizes spend within a planning group, but not across different planning groups. This way the user can have different miROAS targets for paid search, paid shopping and paid social channels.

The MMM model and optimization tools are built in the "traditional way". The AI is an additional layer in the technology stack, using the MMM results and the optimization tools, as illustrated in the image below:

As mentioned in the previous questions, the AI is an additional layer that sits on top of models and optimization tools built in the "traditional way". That means that all outputs from the AI are traceable back to source data, dashboards and optimization tools within Sellforte.
The AI has specific safeguards and instructions for each prompt type and analysis. As an example, it is forced to use Sellforte Optimizer tool to answer questions about budget optimization across channels.
Seasonality is taken into account in campaign-level recommendations in cases where the platform is allowed to scale spend based on targeted cost or efficiency levels, such as Target ROAS.
We are currently working on including seasonality for campaigns that are using fixed spend limits, such as "daily spend".
Yes, Sellforte can measure all media, including digital channels, offline channels, and own media (such as email, SMS).
Sellforte can also measure the impact of all media to sales in all channels, such as ecommerce, physical stores and marketplaces.
Model validation metrics, such as R² and MAPE are available in the Model Validation view (see screenshot below).
We have not yet developed a skill for the AI to access model validation metrics so that they can be requested from the chat, but this is a great idea, and we'll add it to the backlog!
Sellforte's Next Gen modeling approach uses vastly more data, compared to traditional Marketing Mix Models. The core method is an advanced version of Bayesian Marketing Mix Model that is calibrated with experiments and other data that can be used in forming informative priors. This method is complemented with causal attribution, pre/post analysis of bidding parameters changes, and channel/campaign -specific additional data that reveal info about level of saturation.

We are also very happy to share more: book a short discussion with Sellforte.
The system uses orchestration with multiple agents rather than simple prompting. Under the hood of Sellforte AI, there are different agents answering questions. As an example, Media Planner Agent is built specifically to answer future-looking optimization and forecasting questions using Sellforte Optimizer.
