Hi, I'm Will.

I build safety products at Meta Superintelligence Labs and co-founded Arc AI, a gamified strength training and running app. Knowing how to use AI is the single biggest advantage you can have right now. I started Compounding to share what's actually creating real value in my life, so the people I care about don't get left behind.

Three ways I can help you

01

The Compounding Newsletter

The AI workflows I actually use. Written for people who make things, not productivity systems.

02

Arc AI

App I co-founded for strength training and running. I use it every day and you probably should too if you care about your health.
