Hi, I'm Timothy Buck
I build AI products for billions of people as a Product Director at Meta. Before that, I brought privacy and encryption to the same scale.
AI for People
I believe AI should give people the power to accomplish their goals and help them be better friends and family members. I brought Meta AI to Instagram, Facebook, and Messenger: chat, voice, personalization, and creative tools used by hundreds of millions of people. Now I lead agentic AI across Facebook and Messenger: AI that gets things done for you. We recently shipped Muse, and we’re growing it and integrating it more deeply into both apps.
End-to-end Encryption
Project Armadillo began with me and 3 other people in a room. After rebuilding hundreds of features top to bottom, more than a billion people can now know that only they and the person they're talking to can access their personal messages and calls.
Privacy Features
I believe people should be in control of their digital lives. I shipped privacy features across Instagram, Facebook, and Messenger: app lock, editing sent messages, turning off read receipts, and Message Delivery Controls that let you decide whose messages reach your Chats list, your Message Requests, or are blocked entirely.
Before Meta
I grew up in the Blue Ridge Mountains of North Carolina. I worked as a self-taught engineer to help pay for college. After graduating with a degree in International Business, I worked at HP, became Head of Product at a fintech startup, and co-founded Nicer, a product studio that still runs today. Going from zero to something real (and learning when to walk away) shaped how I build products and teams.
Beyond Work
I live in San Francisco with Alyssa Guerrero.
Sometimes you'll find me helping her with Frenzy Faire, her retail store of handcrafted and vintage goods in North Beach.
I've read a book each week for over a decade and keep a list here.
I enjoy travel photography and sculpt at our neighborhood pottery studio.
