David Spiegel

Product + Growth in San Francisco.

I find where products lose people, and fix it.

I work at the intersection of growth, monetization, and UX — across AdTech, DTC healthcare, and startups. I studied psychology at NYU, so I start with behavior and intent before features.

Available for workconsulting, product, or growth with startups.

Building

  • Obeagle

    Omegle, but for dogs. A fun one.

  • AdTech AI eval

    One of the first AI evals for an AdOps workflow — synthetic tasks with deterministic verifiers.

  • AEO platform

    An AI-search-optimization platform. In development.

About

I think a lot about behavior and intent — most product problems are really attention, motivation, or friction problems wearing a costume. I care about UX and the small stuff, and I’d rather build a rough version of something than write the perfect doc about it.

Years ago I tried to build an app called Pearup in college. It never launched, but it’s what made me want to get good at this.
