The platform

Four products, one private account

From a full business phone system to autonomous agents to AI in your pocket โ€” all running through the same self-hosted gateway, on hardware we own.

Simple usage pricing, and it scales with you: volume discounts based on usage โ€” the more your team runs through the platform, the better your rates. Talk to us about high-volume pricing.

Why Nexus

Everything you need to ship AI at scale

One account replaces a tangle of provider SDKs, billing logic, and rate limits โ€” across the gateway, the studio, and your phone.

๐Ÿ”€
Multi-modal routing

A single, consistent API for text-to-speech, speech-to-text, image, video, and text generation โ€” swap modalities without changing your stack.

โš–๏ธ
Intelligent load balancing

Requests are balanced across providers by real-time latency and cost, so you always get the fastest, most economical result.

๐Ÿ“ˆ
Simple usage levels

Pick a level โ€” Low, Medium, High, or Max โ€” and stop babysitting a token meter. Predictable monthly pricing across every modality.

๐Ÿค–
Agent orchestration

Run concurrent agent sessions with personas and a coordinator. Build autonomous workflows on top of the same metered gateway.

๐Ÿ›ก๏ธ
Privacy-first by design

We never read or store your data. Only metering metadata is recorded โ€” your prompts and outputs never touch our logs.

๐Ÿข
Never cut off

Go over your usage level and you're simply slowed down โ€” never hard-blocked. Upgrade any time for full speed.


How it works

Live in three steps

1
Create an account

Sign up and pick a usage level that fits your workload.

2
Drop in your API token

Point your existing client at Nexus. One endpoint, every modality.

3
Ship & watch usage

Track tokens, latency, and cost per provider in your dashboard in real time.


For business & hospitals

Want the whole stack on your hardware?

We're AI experts. We'll deploy the gateway, calling, studio, and a branded mobile app onto infrastructure you control โ€” for a one-time integration cost โ€” so nothing ever leaves your walls.

๐Ÿฅ
Privacy-bound by default

For clinics, law firms, finance, and agencies who legally can't put data in someone else's cloud. Self-hosted, audited, on metal you own.

๐Ÿ”ง
We set it up

A fixed integration cost gets the full stack installed, tuned, and running on your hardware โ€” then it's yours to run.

AI experts on call

From model selection to voice latency, we've built this end to end. Lean on us for the parts that are hard to get right.
