The AI OS is the custom layer we build above your existing stack. It coordinates your CRM, docs, spreadsheets, email and databases into one place where work actually gets done. Your team stops switching tabs and starts approving decisions. Less busywork, fewer missed handoffs, and a system that improves the longer it runs.

Rohan Mehta · Hindustan Times ![Aashish Pahwa, founder of Koso](/assets/aashish-CARnh3o6.webp) The human behind the AI ## Want to know the human behind this AI system? Hi, I'm Aashish Pahwa. I founded Koso to build AI the way good software has always been built, bespoke, opinionated, and engineered around the people who actually use it. Before this, I spent a decade building digital products, growing brands and writing about the internet for millions of readers. I've shipped editorial platforms, marketing engines and consumer apps. Koso is the place where all of that meets custom AI. Every engagement runs through me. If you work with Koso, you're not getting a sales pod and an account manager. You're getting a small team that thinks like founders and a direct line to the person who started the company.

How is this different from buying an AI SaaS? Off-the-shelf tools solve one generic problem. We build software around the workflow, the data and the moat that only your business has. You own the code, the agents and the roadmap. How long until something is in production? Who owns the code and the IP? What about data and security? Which models do you use? Available for new builds ## Let's Build Your Custom AI Tell us the workflow, the product or the moat you want to put AI behind. We will tell you exactly what it takes to ship it.
