Alt HorizonAI ConsultancyUK

AI adoption that pays for itself. Without defaulting to the cloud.

Most AI projects fail at the economics and governance layer, not the demo layer. We model all three options — cloud, self-hosted, hybrid — then recommend the one that survives cost, compliance, and operational reality.

01 · The problem

Three places AI adoption stalls.

Most AI projects don't fail at the demo. They stall between "we picked a tool" and "it pays its way." The teams we see struggling have usually skipped one of these.

Click each to expand

01 Unpredictable costs

Token-based pricing means your bill scales with usage, not value. A successful pilot can become an unbudgeted line item within a quarter.

Symptom · runaway opex

02 Data sovereignty and compliance

If your data is regulated, sensitive, or commercially valuable, "send it to someone else's API" is a decision, not a default. Most teams make it by accident.

Symptom · audit findings

03 Tooling without a thesis

Copilots, agents, RAG, fine-tunes. The market sells answers before the questions are clear. We start with where value is created, then choose the tooling.

Symptom · pilot fatigue

02 · Consultancy

Three engagements. Honest scopes.

A typical engagement runs from a half-day Assessment through to live, measured deployment. Scope scales with ambition.

Scope · 01

Discovery Sprint

03 · Delivery

Five phases of delivery.

After the discovery week. Same five phases on every engagement, whether you're scoping a single use case or a portfolio. Each phase has a deliverable, and a failure mode worth knowing in advance.

01 Assess

Use-case longlist, current state, data sensitivity. Stakeholder interviews and a risk-appetite conversation with the commercial owner.

02 Prioritise

Score each longlist item on impact, effort, and residual risk. Quick wins separate from strategic initiatives. The top 3–5 go to modelling.

03 Model

TCO and ROI across cloud, self-hosted, and hybrid. Assumption ranges, not single-point forecasts. The model that has to survive a finance review.

Deliverable · Cost / ROI model

04 Implement

Phased delivery. Milestone-based, ROI-gated. Governance and security set up before go-live, not after.

Deliverable · Live solution + baseline

05 Measure

KPIs from Assess, reported against. Quarterly review of the ROI model. Outcomes documented as the input to the next decision.

In production with Reef

Horizon Platform. The operational surface, when you want one.

Engagements don't require it. When it's there, the work becomes live, measurable, and yours. One dashboard for agents, tickets, alerts, change workflows. Policy, usage, and ESG controls underneath. Self-hosted, no data leaves your perimeter.

  • 01Your data stays inside your perimeter. Always.
  • 02One operations surface for Windows, Linux, macOS, and containers.
  • 03Adoption that can't outrun governance. Policy enforced at the edge.
  • 04Security posture in the same view as AI workflows. One audit trail.

04 · Outcomes

What measurable AI looks like.

Below is a live deployment of Horizon Platform — Reef, a workspace booking platform, running in production on Alt Horizon-managed infrastructure. The shape of the proof a CFO or CTO will expect, with a real customer on the other end of it.

Reef · Workspace platform

Workspace platform on Horizon, self-hosted in the UK.

Reef helps people find places to work and helps venues fill empty seats. The application, the database, and the operational surface all run on Alt Horizon-managed infrastructure — single-tenant, UK-resident, with Horizon Platform handling agents, telemetry, and policy. No customer data leaves the perimeter. Performance and cost metrics from this engagement will be published here as they're signed off.

05 · Tokenomics

Price your AI workload, honestly.

Cloud, self-hosted, and hybrid priced side by side on your own assumptions, then ranked on real UK numbers. Below is a sample workload, drawn from the tool's live matrix.

Talks to its neighbours

Your scenario carries forward via URL state. Hand it to the ROI article and the calculator pre-fills with your inputs — cost grossed up to include the ops & governance overhead that's usually the bigger half.

06 · Resources

Decision lenses. Not hot takes.

Practical writing on AI adoption for people who have to defend the decision afterwards. Frameworks, benchmarks, and the questions that come before tooling.

01 How we work out ROI with AI

A defensible model in four moves: volume, sensitivity, deployment, payback. With the maths shown. The mistakes that quietly break most ROI cases, called out by name.

02 Do I really need AI?

Five questions that usually decide whether AI is the right tool, before tooling choices are even made. Sometimes the answer is "not yet". That's a defensible decision too.
