The API for LLM tool use

What is your company going to make? Please describe your product and what it does or will do.

We are building an API that enables product, design, and engineering teams to integrate, connect, and automate large language model tools easily. It standardizes how multiple LLM-powered tools are accessed and used in workflows, making it faster to build and operate AI features rapidly.

Where do you live now, and where would the company be based after YC?

We live in New York City, NY and plan to keep the company based there after YC.

Explain your decision regarding location.

We have a small founding team based in New York City, and we want to continue growing here because of our existing network and operational base.
