AI Product Demos

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

We built an AI agent that sells, onboards, and supports users automatically through live, personalized walkthroughs. It replaces traditional sales demos and support with AI-driven conversations that guide users exactly where they need to go in a product, saving time for both buyers and sellers.

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

We live in Los Angeles, CA, and plan to keep the company based here after YC.

Explain your decision regarding location.

We've stayed in LA because it's where we know the market and our early customers, and it keeps the team lean and focused without distractions from bigger tech hubs.

Frequently Asked Questions

Is this the real Primer YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Primer's public data (launch notes, founder backgrounds, product description). It shows how a company like Primer would present itself to YC, not the text they submitted.
