Self-healing prompt injection defense

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

We're building Silmaril, a defense system for AI native apps and agents that automatically detects and blocks prompt injection attacks. It uses knowledge of the app's context to prevent more threats than current defences and does so with lower latency. Customers connect it to frameworks like LangGraph using just a few lines of code.

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

We live in San Francisco, CA, and plan to keep the company here after YC.

Explain your decision regarding location.

We choose to base in San Francisco to stay close to our customers, partners, and the AI startup ecosystem driving demand for prompt injection defense.
