At ImprezzAI, we're working hard to help companies both measure the efficacy of their advertising efforts, and advertise more efficiently by optimizing their campaigns to maximize their return on ad spend.

I led programmatic advertising and data science at CarGurus: two teams that I scaled from 2 to about 25 people during my tenure. Algorithmic Traffic Acquisition (aka Programmatic Advertising) uses online ads to bring valuable traffic to CarGurus as efficiently as possible. Everything is done in-house programmatically via our algorithms and our partners' APIs. This gives CarGurus the flexibility to develop solutions tailored to their needs and data, and has allowed them to compete and win in the auto vertical. Components of the system we built include the following: - multi-touch counterfactual attribution model - Bayesian approach to understanding performance at an atomic (e.g. keyword) level - real-time performance-based bid adjustments and budget reallocationData Science is a research team that finds value in data all over the company (not restricted to advertising). Here are some example projects: - generate real-time recommendations based on users' shopping behavior - measure the impact and interaction of TV, radio, and online advertising using modern causal inference techniques - estimate the long-term conversion rate of hundreds of millions of keywords - improve our understanding of the fair market value of a car
