WORK HISTORY
CTO @Pebblepost
New York, NY, US
CTO at PebblePost, where I lead engineering, data, and AI across our commerce identity and performance marketing platform.Since 2023, my focus has been the intersection of AI, identity, and incrementality in adtech. My team and I have rebuilt PebblePost’s identity spine – evolving our Graph and Individual ID into a large‑scale, privacy‑first asset that connects intent and $100B+ in annual transactions to measurable business outcomes. That graph now powers Programmatic Direct Mail and CTV, improving reach, match rates, and the quality of every optimization and measurement decision. We\'re diving into privacy-by-design approaches to leverage LLMs and agentic workflows to unlock our unique transaction purchase powered data asset covering the entire US household footprint in a channel agnostic manner including CTV and programmatic direct mail (PDM). The throughline is incremental performance – lift‑based, brand‑verifiable outcomes rather than surface‑level CTR or last‑click metrics.
