# Custom AI development

Gateway Global is a London AI company that designs and builds custom AI for real work: AI agents that finish tasks, voice AI, on-device and hybrid AI, and the secure infrastructure and integrations underneath.

Last updated 25 September 2026

## What we build

- **AI agents** that complete tasks end to end.
- **Voice AI**, from the technology behind Prime Assist.
- **On-device and hybrid AI** with model routing, from Prime Edge AI.
- **Secure AI infrastructure.**
- **Integrations** with the systems you already use.
- **Data pipelines** with privacy engineering built in.

## What makes our builds different

- **Designed for production from the start**, not rebuilt after a prototype.
- **Safety and security reviewed** before launch.
- **Results measured** against goals agreed with you.

## Questions people ask

**Which AI models do you use?**

We choose the model for each task, and explain why we chose it.

**Can you work under our security requirements?**

Yes. We review your security requirements at the start of a project and design to them, following the same principles as our own secure AI infrastructure.
