Custom AI agents · Claude enablement

Agents that do real work, without degrading your standards.

We build custom AI agents that run in production, and we get your team using AI to a standard you can trust. Hands on, embedded with your team, whatever size organisation you sit in.

Custom agents and Claude enablement, delivered hands on. Led by a CTO with 10+ years in applied AI delivery.

The gap we work in

The problem is not adoption. It is what happens when adoption scales.

Almost every rollout starts well. A handful of early adopters push agents hard, output climbs, and leadership sees the numbers. Then more of the team comes on board, and quality starts to slip — not because the technology failed, but because nobody decided how the organisation would maintain its standards as usage grew.

That is the gap we work in. We help you turn your standards into shared infrastructure, so the productivity gains you were promised actually arrive, everywhere, and hold as you grow.

What we see go wrong

The failure patterns are predictable.

We have observed an increasing number of Claude rollouts and spotted some common failure patterns. It is rarely the technology — it is scaling with no strategy for maintaining standards. Three come up again and again.

01

The review bottleneck

A large engineering org rolled Claude out and PR volume climbed. The cost landed on code review: senior engineers drowning, quality slipping below the pre-Claude baseline, some refusing to review AI-generated work at all. Throughput looked great until the people who keep the codebase healthy stopped absorbing the cost.

02

Confident, unchecked output

Claude lets non-technical teams produce knowledge work at speed — proposals, commercial terms, analyses in minutes, not days. But confident, polished slop rides along with it, more than anyone has time to verify. We routinely see documents go out with hallucinated clauses and out-of-date pricing. The volume hides the errors until one reaches a client.

03

Standards trapped in people's heads

The most common one. A few power users learn what good looks like, but that knowledge never becomes shared infrastructure. Everyone else starts from zero, so the rollout works for some and not others.

The fix is the same in every case: decide how you will maintain standards before scale forces the question. That is exactly what the Claude Skills Playbook lays out.

What we do

Three engagements. One standard of quality.

A narrow focus, on purpose — custom agents and Claude enablement, delivered hands on, rather than a little of everything.

01

Custom Agents

We build agentic systems that do real work in production, tailored to your workflows, and not just for engineering. Research, analysis, and drafting agents for operations, legal, finance, and marketing teams. Agents that work across your codebase and tooling. Agents embedded directly inside your own product and connected to your data. We build on whichever agentic harness fits the job, and we build hands on, alongside the people who will actually use the work, so they can run and extend what we deliver rather than depend on us to keep it alive. Not demos. Systems your people and your customers rely on.

Claude Enablement

Get your organisation onto Claude and Claude Code with the guardrails that keep quality high. We help you design the rollout: how teams adopt Claude for Enterprise, how engineers work with Claude Code day to day, and how you set standards, review processes, and version control so the work stays consistent as more people come on board. The outcome is adoption you can trust — not a tool that quietly drifts.

Workshops

When Claude is rolled out across a team, the failure is rarely that people refuse to use it. It is that most never learn to use it well. Volume climbs, quality slips, and your most experienced people get buried reviewing work they cannot trust on sight. Our workshops close that gap. Hands-on sessions, not slideware, and not limited to engineering: we work with product, operations, legal, marketing, and leadership as readily as with developers, because the biggest gains often sit outside the engineering function. Teams leave producing work to your standards and in your organisation's voice, not the model's default.

Public sector · Workshop → build

From a workshop to a build: an expert public-sector team

The IT and engineering teams inside a privacy-first public-sector organisation were curious about AI agents but wary, with real questions about the technology's limitations, the risks, and the impact on their work. We started with a workshop that took them from the origins of the technology, through its current state, to its honest limitations, and answered the strategic questions directly in a Q&A.

That session built confidence across the organisation. Its service development and innovation team then commissioned us to architect an internal software research agent: one that reads across their codebase, issue tracker, documentation, and process logs to help engineers find context and diagnose problems, without their code ever leaving a governed environment. We designed the architecture end to end, including the tooling integrations, guardrails, and governance their strict privacy requirements demanded.

"John delivered an outstanding presentation to our team on the topic of AI Agents. He conveyed a complex subject, from its origins and current state of technology to its limitations, in a simple, clear, and easily comprehensible way. We were particularly impressed by his expertise during the subsequent Q&A: well-founded and practical answers to strategic questions, and to the concrete impact of AI on our organisation. We wholeheartedly recommend him as an expert and thought leader."Head of Innovation · public-sector organisation
SaaS · Embedded agent

An AI agent embedded inside a live SaaS platform

A software company wanted an AI agent working directly within their product — connected to their platform rather than bolted on beside it. We built and embedded the agent so it runs as a native part of the user experience, in production.

Community · Patterns in the wild

What the wider community is building on these patterns

The methods we teach are being put to work well beyond our client base. A six-person startup in Berlin used our Always-On Agent approach to run shared, multi-user agent sessions connected to their mail and databases, and adapted our Recursive Language Model pattern to build a complex tender-analysis workflow.

"It was your 'Always On' video that really helped us figure out how to manage sessions for our small team. It feels much smoother working as a team now."AI startup founder · Berlin

The strategy layer most rollouts are missing.

If you are rolling Claude out across your organisation, the hardest problem is maintaining standards as you scale. These free resources give you the foundation we build on with clients.

The Claude Skills Playbook

Your standards cannot live in people's heads. The Playbook is a practical guide to turning them into shared infrastructure: how to build and govern Claude Skills across a growing organisation so quality holds as more teams adopt them. This is the strategy layer most rollouts are missing — the one that decides whether a rollout works for everyone or just for a few.

Mastering Claude Skills

From First Principles to Organisational Scale — our self-paced course covering everything from the fundamentals to deploying Claude Skills across an organisation. It is the same thinking we bring to client engagements, made available to individuals and teams who want to learn the method directly. 40+ practitioners have enrolled so far.

"I really enjoyed it. For me, it covered everything needed to get started with skills. The explanation of the different levels was especially helpful, and being 'forced' to implement a first skill was exactly the right push."AI Researcher · Fraunhofer

Why us

About Brainqub3

John Adeojo, Founder and CTO of Brainqub3

Brainqub3 is led by John Adeojo, a CTO with more than ten years in applied AI delivery. We build custom agents and help teams use them to a standard they can trust. We are platform agnostic: we have delivered systems on Claude, NemoClaw, Codex, and other agentic harnesses, and we use whichever fits the job in front of us. When the choice is ours, we reach for Claude, because we believe it is the strongest foundation for agentic work: a serious safety posture, deep documentation, and a fast-maturing skills ecosystem.

We embed with your team and build alongside the people who will actually use the work. You get senior, hands-on delivery — not a strategy deck and a junior to execute it. We keep our focus narrow on purpose, and we publish openly so our thinking is out in the open rather than behind a sales deck.
