The profiles we work with

Data science and modelling
Bayesian models, response curves, priors, diagnostics. The point is not to stack models but to ship one a marketing team can challenge.
Media strategy
Working alongside brand teams: framing the data, reading the results, holding the budget arbitrations that follow. You need to have seen media plans up close.
Product engineering
Connectors, data pipelines, web platform, MCP server. A lot of heterogeneous data to make usable, and an interface that has to stay readable.

Spontaneous application

Write to us with something you have measured, built or arbitrated, and what you would want to do here. One concrete example beats a cover letter.
