About Flow Nexus AI

Founder-built. Hands-on.
Hungry to earn your first reference.

Flow Nexus AI is a UK AI agency run by its two founders. We audit your operations, build the AI that fixes them, and manage every system we ship.

What we are

A small UK agency that builds AI systems and stays on them after launch.

We started Flow Nexus AI because most AI work for UK SMEs was being sold one of two ways: a generic SaaS subscription that never quite fits, or a six-figure consultancy engagement that ends at “deployed”.

We do neither. Every system we ship is custom-engineered for one business — yours. We build it with you, ship it in 30 days, and stay on it after launch — because AI workflows are only as useful as how reliably they run on day 90.

Our flagship build is Virtual Clerking for UK education governance — AI-assisted clerking for school and multi-academy-trust boards, with the human-in-the-loop design that statutory governance requires.

The founders

Two of us. Both on every build.

How we work

Audit. Build. Manage. With more substance than the slogans.

Most agencies stop at “deployed”. We stay on each system after launch — that’s where the real work happens.

01

We audit

A 30-minute call with both founders. We map your operations and find where AI saves staff time or captures lost revenue.

Cost / time: Free. 30 minutes. No commitment.

You walk away with

  • A documented map of your current ops, by role
  • The two or three highest-ROI automation candidates, ranked
  • A clear ROI estimate with the assumptions written down
  • An honest answer on whether a build makes sense for you yet

What we need from you

30 minutes of your time, plus access to one or two team members for context.

02

We build

Founder-built, end to end. No contractors, no juniors. We design with your team, not for them.

Time: Most builds are live in 30 days. Smaller workflows ship in 1–2 weeks.

You walk away with

  • A working AI system in your stack — your CRM, your phone, your calendar
  • Voice, persona and escalation rules approved by you in writing before launch
  • A documented data-flow diagram for your auditors and any future engineer
  • A change-log of every prompt, integration, and rule deployed

What we need from you

Sign-off at three checkpoints (design, dry-run, launch) and one or two short calls per week.

03

We manage

Live system, monitored 24/7 by us. Every misroute flagged, every Monday a 5-minute review of what to refine. The system gets better over time without you doing anything.

Time: Ongoing. Cancel any time, your system stays live and your data stays yours.

You walk away with

  • 24/7 uptime + error monitoring on every system we ship
  • Weekly tuning of prompts and escalation rules
  • Monthly written report on volumes, conversions, and what we changed
  • One quarterly review with both founders to set the next quarter's priorities

What we need from you

Five minutes a week to review the management dashboard. Less, if you'd rather.

Why us, why now

The honest case for hiring a new agency.

We’re early. That’s a feature, not a bug. Here are the four reasons it lands in your favour.

  • You talk to us. Every time.

    When you book an audit you get the founders. When we build you get the founders. When something breaks at 9pm on a Tuesday you get the founders. There is no account-management layer to navigate around.

  • Hands-on builds, not contractor passes.

    Every line of every system we ship is designed and written by Archie and Kieren. We're small on purpose. When you scale us, we scale you carefully — not by adding a junior to your account.

  • Hungry. By design.

    We're early. We need a small set of great first references more than we need margin. That means we'll over-deliver on early builds — extra polish, extra calls, extra responsiveness — to earn the case study we'd be proud to publish next year.

  • UK-shaped, regulation-aware.

    Most of our pipeline sits in regulated environments — UK education governance, healthcare front-of-house, accountancy admin. We design with the Academies Financial Handbook, GDPR, and your auditors in mind, from the first conversation.

What we can credibly claim today

  • 30 days

    Most builds delivered in 30 days or less.

  • UK-based

    GDPR-compliant by default. Data stays in the UK.

  • Founder-built

    Every system is designed and shipped by the founders.

  • 24/7 monitored

    Every system we ship is monitored around the clock.
