UIMessage is an IntrSI product. We built its message router, media pipeline, call signaling, group-call server, relay and encryption ourselves. Owning that stack lets us inspect and improve its privacy and performance trade-offs directly.
Independent by design
When you control the whole system, you control the trade-offs. We choose privacy and quality first, every time — and we can move fast when it matters.
We build the tools we wish existed, and we sweat every detail.
