Now taking Q1 2026 engagements

AI, installed by a senior operator.
Not another tool rollout.

An ex-SVP, VP, GM or CEO — with twenty-plus years of operating experience — spends 90 days inside your business, backed by a configured AI agent stack. One workflow, in production, at the end. Fixed fee. Outcomes agreed up front.

01The gap

Three-quarters of mid-market firms use AI. Only 14% have it in the work that matters.

Not because tools are missing. Because the senior person who could point them at the right processes, connect them to real data, and get the team to actually use them isn't in the building.

01Blocker

No internal tech leadership

No CTO, no Head of IT to own a sustained AI programme. The owner ends up doing it in evenings.

02Blocker

No Big Four budget

£200k+ engagements don't justify themselves at £5–25m revenue. The math doesn't work.

03Blocker

No senior advisor on call

No fractional CIO, no strategist to sanity-check the next decision. You're on your own.

02Why tools aren't enough

A licence is not a workflow.

ChatGPT, Claude, Gemini, Copilot are tools.

Powerful ones. Someone still has to work out which processes to point them at, connect them to your data, adapt them to your voice, and get the team to actually use them.

The firms winning with AI had a senior person inside.

Someone who could translate operations into prompts, judge outputs, and hold the change through the messy middle. Most £5–25m businesses don't have that person.

Series-X sells the senior person.

The agent stack is their leverage — not the product. You buy judgement, delivered at speed the incumbents can't match.

03The engagement

Four things make a Series-X engagement different.

No junior consultants. No vague timelines. No surprise invoices.

01Principle

A senior human in the room

Not a junior consultant. Not a chatbot. A named operator with 20+ years of relevant experience leads every engagement.

02Principle

An AI agent stack does the heavy lifting

Analysis, content, integration, automation — handled by configurable agents under the operator's direction. Speed and depth a small team alone couldn't match.

03Principle

90 days. Fixed fee. Fixed scope.

No change orders. No expense passes. No surprise extensions. The commercial contract mirrors the delivery contract.

04Principle

Outcomes signed up front

We name the success criteria before any work begins, and close out against them — not against effort.

04The model

Senior operator up front. AI doing the repeatable work behind them.

The client meets one person. Behind them, a configured AI agent stack compresses months into days — workflow, integration, knowledge, content, monitoring. Agents never speak to the client. The operator directs, reviews every output, and applies judgement to everything that matters.

Big Four

Analysts supervised by a partner you see twice. 9+ months. £200k+.

Series-X

Senior operator + AI stack. 90 days. Fixed fee. Same seniority every day.

07Fit

We're picky about fit. It's how the model holds up.

This is for you
  • You're owner-managed, £5–25m revenue, growing.
  • You have no CTO and no Head of IT.
  • You don't have a Big Four retainer.
  • You don't have a fractional CIO or CTO.
  • The owner is personally sponsoring the change.
This isn't for you
  • You have internal tech leadership running an AI roadmap.
  • You already have McKinsey or Faculty on retainer.
  • You want headcount cut — we don't do that.
08Use cases

Productised workflows we install — not bespoke from scratch.

Each one is a named workflow with a baseline, a target, and a way to measure it on day 90. Drawn from the operations of the businesses we focus on.

09Industries

The UK markets we know cold.

Scored across six criteria — willingness to pay, urgency, AI fit, fragmentation, referability and our access. Three anchor verticals lead.
