​A curated evening at AngelList HQ for founders and engineers building the agentic era.

​Life after 🦞

​OpenClaw proved agents can work.
It didn't prove they can be trusted.

​The question is no longer "what can agents do?" — but what happens when they touch real tools, real data, real money, and real users with no one watching. The engineering problems are just getting started...

​Constructive Build Night is for agentic builders.

​We'll spend the evening together at AngelList HQ — founders, engineers, and technical leaders building across the agentic stack: the agents themselves, the interfaces they speak through, the infrastructure they run on, and the trust models that make any of it production-ready.

​Short lightning demos from the room, good conversation, and just hanging out and building together.

​There will be lobster rolls. Space is limited.

​What to expect

• ​A curated room of builders

• ​Lightning demos and open conversation on what it actually takes to ship agentic software

• ​Lobster rolls, drinks, and the kind of room where your next cofounder, first customer, or lead engineer might be a conversation away

• ​The first night of a recurring series for people building the agentic era

​Who should be here

• ​Founders building AI agents, products, infrastructure, or developer tools

• ​Engineers working on agent frameworks, voice, backends, data, or tooling

• ​Technical leaders thinking about trust, permissions, reliability, and how agents actually get to production

• ​Anyone building past the demo and into the real world
