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 AI-powered consumer intelligence tools, and used them to find a market gap: consumer tech had largely ignored older adults. So we built Hotline, a team of friendly experts seniors can call, text, or email for help with anything: tech, travel, everyday life.

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 acquired by Airtable.

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, psychology, and design.

Before Bayes, I was a product manager at Twitter. I worked 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.
