AI Lab · London · In partnership with AI Overlords

Voice AI, GCP and agents
shipped in 4-6 weeks.
Not 4-6 months.

People-centered AI products and consultancy. We ship the lab's own product line and the same team delivers custom builds for your business — never one at the cost of the other.

Voice agents, GCP builds, custom RAG, CI/CD pipelines, and multi-agent architecture — deployed by our team, owned by yours. Our product line (SOS.VU, cam.vu, CALEL Legion, Aquaman) funds the lab and stress-tests every technique before we bring it to you.

PRE-VU Consultancy Agent · Voice AI

Talk to our voice AI. Ask anything about PreVU Labs.

Voice-first · typed fallback if you prefer. Ask about the four consultancy pillars, any of the 13 products, or how we work — the agent can book you a discovery call or open the intake form when you’re ready.

Consultancy · ship-first pattern

How an implementation runs.

4-6 weeks typical. Scope in week 1, build weeks 2-3, QA + evals in week 4, ship in weeks 5-6 with a founder-narrated runbook. Every engagement produces a case study, a live surface, and code your team owns.

Let's work together.

Voice AI. GCP. Custom agents. RAG. CI/CD. Shipped on-site or cloud — you own the code.

Products fund the lab. The lab funds the ambition.

From the lab

Writing from the workbench.

What we are shipping, what we are learning, what we would build differently. Written from the desk, not the deck.

Why we ship Voice AI in 4-6 weeks, not 4-6 months

Turn-taking sub-350ms is table stakes. Warm human hand-off is table stakes. What makes the difference between a demo and a working production agent is the eval loop — and how tight the scope was on day one.

Where GCP earns its price and where it doesn't

Vertex AI, Cloud Run, BigQuery, Firestore, Pub/Sub. Where each earns its cost line and where it is a tax you pay for convenience. Coming soon.

Multi-agent handovers · how CALEL Legion routes work between LLMs

Handover ladders, state monitors, and how to stop drift between agents built on different LLMs. Coming soon.
