Building Developer Infrastructure at Scale : Office Hours with Jim Everingham

February 3, 2026

Office Hours

Meta’s first internal AI agent went from zero to thousands of engineers using it daily. That doesn’t happen by accident. On Tuesday, February 25th at 5:30 PM Pacific, the person who built it, Jim Everingham, will explain how.

Jim is the CEO & co-founder of Guild.ai. Previously, he led Meta’s developer infrastructure organization & was responsible for building Meta’s first internal AI agent, work that moved from experimentation to real adoption across engineering teams.

Before Meta, Jim built developer platforms at Instagram & Yahoo, giving him a unique perspective on what scales, & what creates long-term friction.

During this Office Hours, Jim & I will talk about :

• Building Meta’s First Internal AI Agent : What it took to drive real adoption inside a large engineering organization, including integration into developer workflows, trust, & reliability challenges.
• AI Agents in the Real World : Where agents are delivering value today, where they break down in production, & which design patterns survive beyond demos.
• Scaling Developer Infrastructure : Lessons from building platforms at Meta, Instagram, & Yahoo, including early decisions that compound versus those that quietly create long-term friction.

This session is designed for founders & engineering leaders who are actively building & deploying AI systems today. The goal is a candid, grounded discussion focused on what actually works in production & what mistakes are hardest to unwind later.

If you’re interested to attend, please register here. As always, submit questions through the registration form & I’ll weave them into the conversation.

I look forward to welcoming Jim to Office Hours!
