Hi HN! It’s been three years since we launched LangChain as an open source package. Since then, we’ve evolved into a broader platform for agent engineering (LangGraph, LangSmith). Our tools now power AI teams like Replit, Clay, Harvey, Vanta, Cloudflare, Rippling, Cisco, Workday, and many more. Our goal has always been to figure out what the agents of the future look like, and then build tools to help make them real.

Today we’re excited to announce new funding (at a $1.25B valuation) to allow us to continue building the platform for agent engineering, as well as new features and products.

And what I’m most excited about today is that we’re launching a number of new features and products: an insights agent in LangSmith, 1.0 releases of LangChain and LangGraph, and a no-code agent builder. We’ll talk a lot more about these throughout the week.

I’m excited to see how you like these new releases and get feedback. I'll hang out in the comments here for a while to answer any questions folks might have.
