I build product and data organizations that turn complex decisions into real outcomes.

For over 15 years I've led product and data teams at Hearst, Viacom, and venture-backed health and consumer technology companies, including as Chief Product Officer. I'm focused on roles where product, data, AI, and organizational change come together.

Background

Product, data, and organizational change.

I've spent my career at the intersection of product, data, and organizational change, building platforms and teams that have to work together across disciplines. My experience spans digital media, multi-tenant platforms, data and AI products, and consumer health.

Currently, I serve as VP of Product for U.S. and International brands at Hearst Magazines, leading strategy across a global portfolio that includes Elle, Esquire, Men's Health, Delish, and Cosmopolitan. I work with regional CEOs and editorial leaders to drive engagement, personalization, and data innovation across diverse markets.

Before Hearst, I built and led product teams at four venture-backed healthcare startups, including Parsley Health and Vori Health, where I served as Chief Product Officer and developed AI-powered patient engagement tools and a computer vision physical therapy app. Earlier, at MTV/Viacom, I built their first social data team and created patented machine learning products that supported 500+ brands and generated over $50 million in new revenue.

Advisory

Selective, senior, specific.

I advise a small number of leadership teams on AI strategy, data platforms, and product organization. I'm selective: the best fits are teams with a hard, specific problem, not teams still deciding whether AI is worth exploring.

Hands-on engagements (positioning, content systems, site and product builds, measurement) run through my studio, NiceSalt.
