Sellforte

Sellforte is a marketing measurement and optimization platform designed for retail and ecommerce brands. It unifies incrementality testing, marketing mix modeling, and attribution correction into a single always-on system. By combining these three foundations, the platform eliminates contradictions between separate workstreams and provides a unified view of media investments across markets.

The platform features an Experiments Hub that unifies geo lift tests, conversion lift studies, and A/B tests to establish causal truth, which then feeds back into the marketing mix model to sharpen accuracy. It uses an always-on causal Bayesian marketing mix model to fill gaps across channels and calculate marginal returns on ad spend. Additionally, Sellforte applies calibration multipliers derived from experiments and models to correct attribution, delivering true incremental return on ad spend at the campaign and ad-set level.

Sellforte supports closed-loop optimization by measuring total spend and incremental sales, planning budget changes through scenario simulations, executing approved recommendations directly via API connections to ad platforms like Meta, Google, and TikTok, and tracking real outcomes against modeled counterfactuals. The platform also includes Sellforte AI, which connects the operating system with specialized agents for incrementality testing, media planning, and media buying. It integrates with over 500 data sources, including major ad platforms and data warehouses such as Snowflake and BigQuery.

Sellforte suits enterprise teams and retail brands seeking multi-market measurement, scenario modeling, and scalable budget optimization.
