Vinay built the models behind every incrementality test Stella runs. Before Stella he led data science at an agency, the person clients called when they wanted proof the marketing was working, after years in data science in London at Contingent and Experify, building the production pipelines that turn raw events into numbers you can trust.
Every holdout Stella runs uses the same methodology, the same statistical guardrails, and the same reporting, whether you're self-serve or working directly with our team. Nothing gets simplified because a deadline moved.
You shouldn't have to take our word for a model, which is the point of a holdout: Stella shows you the counterfactual, the confidence interval, and the assumptions underneath, so you can check the work.
Most measurement tools report what happened. Stella tests what actually drove it.
