Shaachi builds AI-security products that let teams adopt LLMs on sensitive data — safely, and provably.

Our flagship, Gatekeeper, is a security proxy that sits in front of the OpenAI and Anthropic APIs. On each call it redacts sensitive data (PII/PHI) before the prompt leaves your environment, screens for prompt-injection, and produces an audit-ready evidence packet — the record you hand to an enterprise customer's security team to show data was protected and every AI call is accountable.

The problem we solve: a health-tech startup ships an AI feature on patient data, then an enterprise customer's security team asks, "What happens to our PHI before it reaches the model — and can you prove it?" The deal stalls in review. Gatekeeper unblocks it.

We began as an AI SDR product — still serving sales teams today — and pivoted into AI security when we saw how many teams were blocked from shipping AI on regulated data. Our focus now is helping health-tech and other regulated builders move from "we can't put sensitive data near an LLM" to "we can, and we can prove it."
