HumanLayer is an API and SDK that lets AI agents contact humans for feedback, input, and approvals. Our customers use HumanLayer as a building block in AI agents that safely and reliably do risky things like manage cloud infrastructure and database migrations.

Our mission is to enable the safe deployment of AI systems by making human oversight a seamless part of any AI workflow. We're looking for passionate builders who want to shape the future of human-AI collaboration.

Our Hacker News Launch reached over 350 points and almost 200 comments, and TechCrunch Highlighted HumanLayer as a top 4 Enterprise AI startup in the F24 batch

One day in the not-too-distant future, people look back and point to an AI product or experience and say "that was the first thing that kind of felt like AGI". We believe a tool like HumanLayer will play a significant role in making that experience happen.

Here's what a few YC Founders had to say after trying HumanLayer:

Ever since I got hands-on with HumanLayer, I’m asking my whole team to think more about Agentic AI workflows - I used to think agents were not worth the effort to get them to production-grade reliability, but now I'm stoked on what is possible when you bring humans into the loop

Vaibhav Gupta, Founder @ Boundary (YC W23)

Hot take: If you're serious about AI you don't want someone making the "hard AI parts go away"

You want someone making the NON CORE PARTS go away so ALL YOU DO is work on the hard parts.

This is why I'm excited to try @humanlayer_dev
