How we operate

Strategy. Build. Run.
One team, the whole way.

Most consultancies hand off after strategy and disappear before delivery. We don't — the same team owns the path from whiteboard to live system.

  1. [01]

    Strategy

    2–3 working sessions

    We diagnose where AI moves the needle and sequence the bets your team can ship this quarter.

    A roadmap you can defend to the board — not a deck.

    You leave with the plan
  2. [02]

    Build

    Milestones, shipped weekly

    Bespoke applications, automations and integrations, built into your stack and instrumented from day one.

    Working software in production, not a pilot in a drawer.

    Handed over, or operated by us
  3. [03]

    Run

    On the SLAs you name

    We monitor, iterate and improve the systems we ship — for as long as you want us there.

    A system that keeps paying back as it compounds.

    You stay in control either way
Why teams pick us

Accountability, in writing.

  • 01

    Strategy-to-run accountability

    The people who scope it build it and run it. Most firms hand off after strategy and vanish before delivery — we don't.

  • 02

    Dual-jurisdiction delivery

    One team across UK and EU/Nordic — Horaizon Ltd & ApS. GDPR-native EU delivery without a second vendor.

  • 03

    Founder-engineers, hands on

    Founder-level engineers on every engagement, on the keys — not a layer of account managers.

  • 04

    Proven under hard constraints

    We ship production AI under regulated, GDPR-grade data rules. If we can ship under those, we can ship yours.

  • 05

    Built to be audited

    Workflows your operators can read; every step logged, evaluated and explainable.

  • 06

    No vendor lock-in

    Yours to own, fork and self-host. We earn the renewal, never trap it.

What we do

Four engagements,
one process.

Shaped to your scope, timeline and ownership. Build engagements typically run 6–12 weeks; cost scales with scope, integrations and who operates it.

  • AI strategy

    Where AI moves the needle, in what order, at what cost.

    Board-ready roadmap
  • Build & integrate

    Bespoke apps and automations, milestones shipped weekly into your stack.

    Production software
  • Proof of concept

    A focused prototype that tests the bet before you commit the budget.

    Go / no-go, with numbers
  • Expert consultation

    A working session with a founder-engineer on a decision you need to get right.

    A clear answer, no pitch
