Subversive: concrete and connected experience, in the age of plausibility

The board wants to achieve something with AI.

Three levels all work on it, and each sees a different solution.

We provide alignment.

So the outcome you get is the one you wanted.

What we do

Concrete and connected experience, in the age of plausibility.

AI can make any plan or prototype look plausible. We carry the work from the boardroom to the build ourselves: we work out with you what AI should and shouldn’t do in the business, then build it, one piece of work at a time. The advice comes from the people who have to make it work.

Pick the one that sounds like your week.

Writing

Read us before you ring us.

Untangle.

Why we don’t start with AI

Put AI on a tangle and you get a bigger one, faster.

A firm picks up a tangle as it grows: the shared inbox, the bid library, the claims spreadsheet, the old system only one team understands. It eats the time meant for the good ideas. Ask around, and somebody may already be pasting customer emails into a free chatbot. Nobody chose it. That’s one more knot.

Step one: business analysis and architecture

An agent can only follow a process somebody can draw.

So we draw it first. The people who do the work sit round a big sheet of paper with us, and we draw each job as a line, as it runs today. An agent will trip wherever two lines cross, so we straighten those crossings before any agent goes in.

We know from building new capability inside brands and businesses that the better built the engine, the faster it runs.

What step one gives you

You get a one-page plan before any agent goes in.

It says which jobs the agents do, who is accountable for each, and which stay human. It names the tools your staff may use, keeps customer data inside your own systems, and sets out what each agent may see, what it may do on its own, and where its work goes.

Read the guide: Who checks the AI

Refine.

Step two: refine it

The demo is the easy part.

We fit an AI agent to one real process and refine it on live work, with the people who run it, until it saves them time and they trust what it does. It goes no further until then.

Build.

Step three: build it in

We build it in properly, so your own team can run it without us.

An AI agent drafts the tender responses from your past bids. The bid lead reads and signs each one before it goes. Pricing stays human, every step the agent takes is logged and can be undone, and the weeks that went on drafting go on the bids worth winning.

How it works

Untangle the work, and the business starts to move.

  1. Step 1UntangleWe map the process with the people who run it. Then a written plan: the jobs agents should do, who is accountable for each, the ones that stay human, and which AI tools your staff may use.
  2. Step 2RefineWe take the process with the most in it and refine an agent with the people who run it, on real work, until it fits the way your business runs.
  3. Step 3BuildWhat fits goes in for real, built by us for your business, and the person accountable signs it off. Every step it takes is logged, and can be undone.
  4. ThenThe next oneThen the next process, and the next, each one checked.

What you get

A straight answer, from the person who’ll build it.

Dave sits outside your org chart and builds what he recommends, so the view you get is the one he would act on himself. Over twenty-five years he has been the engineer, the architect and the product lead for international brands, and CXO and acting CTO for startups. When a job needs a specialist, and some do, we bring one in and tell you who it is. They work to Dave, and we answer to you for what they do, so there is nobody extra for you to manage.

And when you need more than Dave, we build out a resilient team just for your needs, from our pool of partners, all of whom we have worked closely with.

The record

A dull answer to an expensive problem is usually the right one.

Twenty-five years designing things people use

From Ordnance Survey to startups finding their feet.

All sounds very corporate?

Well, Dave has worked with solopreneurs, mentored MBA students and been in the founding team of several startups, and is working on two now.

He works in enterprise too, but it isn’t where he comes from. He has worked across all kinds of industries.

“Not the conference nonsense, but the reality.”

Seven people who have worked with him, in their own words.

“David actually listens, which already puts him ahead of most people in enterprise AI. He gets what it really is too, not the conference nonsense, but the reality.”

A lot of it is admin with better marketing, and he doesn’t try to dress it up as something magical.

“He can go deep on engineering as a full-stack developer, then turn around and sketch out a clean UI that people enjoy using, then step back and think through where the product should go next.”

What stands out most is his ability to take something technically complicated and makes it very easy to understand. Dave also has a range you don’t see often. Having one person who sees all of that strengthened our team and made our products better.

“In diverse roles ranging from CXO to acting CTO and operating in a fast-paced start-up environment, David proved himself a huge asset.”

He consistently delivered top-quality work for tough taskmasters and demonstrated a breadth of strengths with both the skill and passion to apply them effectively to help meet changing business needs.

“His attitude, knowledge and attention to detail soon helped bring things back online.”

From there Dave worked with us for 6 months on a consultant basis, always on hand to help with any problems, questions or challenges big or small.

“We use David for any key projects that we have and to also sense check thinking and direction, he has an excellent broad knowledge of tech.”

These projects were successful due to a combination of factors but key were David’s experience, knowledge, skill and work effort. I can’t praise him highly enough. I trust David implicitly.

“Dave worked just as effectively with the senior leadership team as with mentoring the junior staff.”

I was always impressed with Dave’s exceptionally broad skill set and his ability to work at all levels, from solving strategic problems to getting into the detail and rolling up his sleeves to get things done.

“His skills range from Art direction to hacking low level repositories to fix annoying bugs”

Having worked with Dave for over 15 years on and off in various roles and various configurations, I can only say one thing, he is a juggernaut of Digital knowledge and capabilities. His skills range from Art direction to hacking low level repositories to fix annoying bugs, he has caught problems that others haven’t even imagined exist and built solutions that were ahead of their time.

How we start

Start with a day.

Your first day

A workshop or a discovery day: a day on how your business runs and where AI could help. You keep the written notes, whatever you decide next.

Then a first piece of work. Or keep us on: three months to begin, then month by month.

We quote for the job, once we know what it is.

A larger organisation? Start here.

On your own? Your first hour is free.

The long version, for small businesses

1 of 3

How much of us do you need?

A retainer. Three months to begin, then month by month.

Partnerships

Starting something new? We’ll be your technology partner.

For founders with a venture and nobody to build it. We plan it and we build it, with you. Terms are open to a discussion, but it’s an offline one.
