Stella helps companies measure the true incremental impact of their advertising across channels like Meta, Google, TikTok, CTV, audio, and more.

It answers questions like:
What revenue would have happened anyway?
What revenue was actually caused by ads?
Which channels and campaigns are truly worth scaling?

Stella does this through three complementary tools:

Incrementality Testing
Designs and analyzes geo holdout and inverse holdout experiments to directly measure causal lift. This is the gold standard for proving whether ads drive incremental revenue.

Always-On Incrementality
Runs continuous causal analysis on live campaigns to give directional, day-to-day reads on incrementality. It helps teams spot waste, validate performance, and catch misleading platform ROAS quickly.

Media Mix Modeling (MMM)
Uses long-term historical data to estimate incremental contribution by channel and guide budget allocation decisions at the executive level.
