# Automation & Agent Build with Ninsei Labs

> For when you have a real process to automate or an agent to build. We go deep on the workflow, the systems it touches, and what "done" looks like. I'll tell you what's feasible now, what isn't yet, and roughly what it costs. Bring the messy details. That is where the design happens.
