SENIOR QUANT UX RESEARCHER

I help product leaders make decisions they can defend.

Most product decisions are made on gut feel, internal opinion, and whoever speaks loudest in the room. I replace that with rigorous quantitative research designed around your specific question and delivered within days.

I'm Svenja Pieritz. My background is in cognitive science and I've spent 7+ years embedding inside product and strategy teams at companies ranging from fast-growth startups to Telefónica and Kiwi.com. I work exclusively on high-stakes decisions: pricing, feature validation, messaging, churn analysis. The choices where being wrong is expensive and being right needs to be provable.

Decision Sprints: a fully managed quantitative research engagement that ends with one clear, executive-ready recommendation.

WHAT I DELIVER

Conjoint analysis, MaxDiff, logistic regression, predictive modelling. The same methods Netflix, Amazon, and Google use to de-risk their bets.

METHODS

Heads of Product, Heads of Digital and marketing leaders at mid-to-large mainly non-tech companies facing decisions too important to get wrong.

WHO I WORK WITH

You get a recommendation, not a data dump. Evidence you can put in front of a board. No analyst overhead, no months-long agency engagement.
