Native LLM = built-in memory from Claude, ChatGPT, Gemini. Tied to one provider, no transparency, no self-hosting.

Self-hosted by default.

KAPEX ships as a Docker container. Deploy in your VPC — AWS, GCP, Azure, or on-prem. Your data never touches our servers. Enterprise adds BYOC and air-gapped deployment.

Early stage?

We're a startup too. If you're pre-seed or in an accelerator, email us — we'll figure out something that works for both sides.
