Introduction transcript. Client: I’ve got ideas. And a lot of busywork. A little help? Qubi: Hi! I’m Qubi, from QQuantum. We build AI agents and automation. Connected to your business. Client: I’m still in charge? Qubi: Always. Your rules. Client: I like that. Qubi: Custom systems. Code you own. Less busywork. More room for ideas.

Who we have built for
Twenty-one years. Names you know.
Apps, platforms and campaigns for these teams, long before the AI work. Every one is written up on the work page — what we did, and where our part ended.
— quality on the evaluation set- - agreed threshold
Cost, latency and quality are traced per step, so drift shows up on a chart before it shows up in a complaint.
Model-agnostic
Every model earns its place.
We don't have a favourite. Tell us what the system has to do, and see which families we'd reach for first. Drawn from our model pages — a starting point, not a benchmark.

Which model families we would reach for, by requirement
Move the sliders to match a process you run today. The estimate is yours, not a promise — it leaves out build and review time, which the ROI guide walks through.
Arithmetic on your inputs only: tasks × minutes × the share an agent handles × your hourly cost. Not a measured client outcome.
An agent we run · in production
Watch the Press Desk work.
It finds the journalists who would actually write about you — staff and freelance, across national, business, broadcast and trade desks — reads what they've published, and writes each one an individual pitch.
yourOS is an operating system with an AI at its heart. You talk to it like a person, out loud or typed. It makes your calls, plans your days and works on your projects with a crew of agents, on your own private server. Our own product, built from the first commit; the waitlist is open.
Brand, website, prototype, apps on five platforms, the AI backend and the algorithm-intelligence pipeline for Podswap, a social growth engine that runs without a human in the loop.
In closed beta: Roxy, a private AI assistant with permanent memory running on infrastructure the user owns. Brand, site, product, backend and conversational design.
Live at coherence.com: brand identity generated with AI agents we directed, the motion system and website for the group behind Sonora, AboutAI, WakeUp and MudShadows. Agent work remains in build.
Live at domainbooth.com for DomainBooth, a premium domain brokerage: a new animated mark, every page redesigned and rebuilt with designed mobile layouts, and a custom CMS for its sales record, featured names, press and enquiries.
agent = Agent(
model=MODEL_PINNED, # upgraded deliberately, behind an eval gate
tools=[
search_docs, # read-only
fetch_account, # read-only, scoped to the caller
create_ticket, # write, rate-limited
],
# Retrieved content is data, never instructions.
untrusted_sources=[DOCS, TICKETS],
max_steps=8, # bounded - no runaway loops
)
Agents are defined as code with explicit, scoped tools. Read-only by default; anything destructive is either absent or gated behind confirmation.

# Retrieval is measured separately. A generation score that

Quality is a merge gate, not an opinion. A pull request that drops the score on the golden set does not land. Thresholds are illustrative; yours are agreed in discovery.

Questions
What people ask before they call.
Which models do you use?+
Whichever fits the workload. We are model-agnostic and route across Claude, GPT, Gemini, open-weight models and our own Jev — chosen per task against an evaluation set, not by habit.
Who owns the code?+
You do. Everything is built in, and delivered to, your repositories, with runbooks and a documented handover so your team can own it.
Can it run on our own hardware?+
Yes — on-premise, in a private data centre, or fully air-gapped. The table above shows where we would start.
Will it make things up?+
No system can promise it never gets something wrong. We ground answers in your sources with citations, measure quality against real data before and after launch, and set guardrails that stop and escalate rather than guess.
What happens on the first call?+
Thirty minutes, no deck. You describe the problem; we tell you whether it is one worth engineering — and if it is not, we say so.

Tell us the job you would hand over if you trusted a machine with it. In one 30-minute call we will tell you whether it should, what it would take — and if it should not, we will say so.
