Hello!

My name is William Simon Wolf / שמעון זאב, but I go by willium online. You can find me on 𝕏, LinkedIn, and GitHub.

Most recently, I founded Gestalt. We built tools for AI-powered customer segmentation, enrichment, and market analysis to help consumer companies better understand their customers, and used them ourselves to find product opportunities.

As we worked with consumer data, we kept finding the same blind spot: consumer technology had almost entirely ignored older adults. It's a real problem with strong demographic tailwinds, and one we felt personally. So we built Hotline, a team of AI experts reachable by regular phone call, text, or email.

My previous startup, Bayes, built tools for visual exploratory data analysis and interactive data storytelling. We used declarative visualization grammars and constraint-based optimization to automatically find the best visual encodings for any dataset. Bayes was backed by Y Combinator and Amplify Partners, and was acquired by Airtable in 2021.

Bayes was rooted in my earlier research at UW's Interactive Data Lab, where I contributed to Vega-Lite and worked at the intersection of statistics, ML, and design.

Before Bayes, I worked at Twitter on Trust & Safety, building data-driven enforcement systems for misinformation, election interference, and harassment.

Erstwhile, I cut my teeth on product marketing and analytics at Oscar Health, international development research at the Harvard Kennedy School, visual data journalism at FiveThirtyEight, social products at tbh, mobile canvassing at Change.org, and what would become UberEATS at Uber.

I studied Computer Science with an emphasis on Data Science at the University of Washington in Seattle.

I ocassionally write essays about the things I'm thinking about. I'm always on the lookout for co-conspirators, thought partners, and friends.

I love to travel and meet strangers, and I'm an avid tea-drinker, beach-runner, weight-lifter, sunset-watcher, and book-reader.

If you'd like to, please don't hesitate to reach out.
