01 • Rented

Six tools. Six fees. None of it yours.

Most stacks are rented end to end. The data sits in someone else's product, behind someone else's pricing. This is an illustration, not your stack.

02 • Reviewed

Keep, replace or build. Tool by tool.

We map what you pay for and decide in writing. Some tools should stay exactly as they are, and the Review says which.

03 • Owned

The pieces worth owning, in infrastructure you control.

Built to a written scope, with an approval step and an audit trail. Handed over with the documentation to run it without us.

How we work

A person stays
in the loop.

Try the approval gate. This is a live demo and nothing leaves the page.

Approval gate • live demo

Nothing consequential happens until a named person approves, edits or rejects it. Every decision is logged.

InputOne invoice export

RulesWritten, versioned

GateA person decides

OutputWaiting for a decision

Draft reply to supplierTwo lines on invoice 1042 differ from the agreed price list. Please confirm the prices.

Status: Waiting for a person

Bounded

One agreed scope before any work starts. Fixed price once feasibility is confirmed.

Controlled

Your infrastructure, your data, a human approval step before consequential actions, and an audit trail.

Handed over

Everything is documented so your team can run it without us.

The Review

From a list of tools
to a written decision.

The Review is a written look at your subscriptions and the workflows around them. It excludes code.

You send the tools you pay for

A list of subscriptions and the workflows around them. Sanitised exports are enough.

We write it up

For each tool: keep, replace or build, and what a replacement would cost to run. Two to three business days.

You decide

Some tools should stay SaaS, and the Review says which. If a piece is worth owning, it becomes a scoped Pilot.

The Starting Question

“What are your five biggest subscriptions, and which feels overpriced for what you use?”

Most software waste is not abandoned tools. It is the core tool everyone uses daily that quietly climbed from £30 a month to £1,200 as your team added seats, contacts, or connectors. We map what you pay for, identify the pieces worth owning, and tell you plainly what to keep.

Honest Boundaries

When we'll tell you
to keep the SaaS.

Self-hosting adds hosting, maintenance and security work, so some tools should stay SaaS. We say so, and the Review shows the numbers either way.

Fast-Changing Interfaces

Tools where third-party UI standards evolve weekly are cheaper to rent than to maintain locally.

Dedicated Compliance

Workflows requiring global certifications belong on specialised vendors.

Negligible Seat Fees

When an existing service costs less than a single engineering maintenance day per year, renting is rational.

Engineering Capabilities

What we build
& hand over.

Four bounded disciplines where owning the technical infrastructure produces immediate operational control.

Core System

Platform Engineering

Production-ready servers, automated backups, zero-trust secrets management, and containerised deployments on hardware you control.

Platform Engineering →

Integrations

Custom Software & APIs

Deterministic webhooks, reliable API bridges, database extractors, and automated business logic without recurring per-seat penalties.

Custom Software →

Interfaces

Websites & Web Apps

Lightning-fast static frontends, headless web apps, and internal operator portals built with semantic accessibility and zero bloat.

Websites & Web Apps →

Ongoing Care

Monthly Engineering Plans

Dedicated monthly senior engineer hours for updates, security patches, maintenance, and new workflow expansions.

Typical Candidates Only

Workflows we scope.

Two representative operational bottlenecks where manual handoffs and multi-seat licensing accumulate significant friction.

Healthcare Staffing

Timesheet to payroll to client invoice: where do the numbers diverge?

When field shifts produce manual spreadsheets, payroll adjustments, and billing discrepancies, an owned pipeline reconciles hours, calculates overtime and margins, and presents a human approval gate before invoicing.

Property Management

Maintenance labour to owner billing: where does a work order stop matching the invoice?

Contractor invoices, trade markups, and tenant recharges often stall in email inboxes. An owned workflow ingests work orders, verifies agreed rate cards, flags divergences, and holds an approval checkpoint before dispatch.

Engagement Process

How an engagement works.

Four distinct phases from initial conversation to self-sufficient delivery.

Fit Call

Free • 15–20 mins

A brief technical call to verify whether your stack has pieces worth reviewing. No sales pitches.

Review

£400 / $500 • 2–3 days

A written audit of your subscriptions, run costs, trade-offs, and what to keep, replace or build.

Scoped Build

From £2,500 / $3,000

A 30-day bounded pilot. One workflow built, deployed to your servers, and thoroughly tested.

Handover & Care

£750 / $950 / month

Complete operational documentation, code repository transfer, and optional ongoing maintenance.

Data Sovereignty

Your servers, your data,
zero black boxes.

We never run shared vendor middleware between your tools. Everything executes on infrastructure you own and control.

Zero Third-Party Relays

Your business logic runs inside your cloud tenancy (AWS, Hetzner, DigitalOcean) or on-premise hardware.

Encrypted at Rest & Transit

PostgreSQL databases and secure volume stores use industry-standard encryption with keys you hold.

72-Hour Security Promise

We will notify affected customers by email within 72 hours of confirming any security incident involving their infrastructure or credentials.

Direct Senior Accountability

Founder-led & technically grounded.

Aethonex is operated directly by an engineer. When you book a Fit Call or commission a Review, you speak directly with the person who writes the code, designs the architecture, and handles the deployment. No non-technical account managers, no junior handoffs, and no outsourced delivery.

What owners ask first.

Do you promise savings?

No. We do not publish savings figures or make outcome promises. The Review shows what each tool costs you today and what a replacement would cost to run.

Will you tell me to build everything?

No. Some tools should stay SaaS, and the Review says which.

Where does the work run?

In infrastructure you control. You hold the credentials, the data path and the documentation.

What do you need from me?

A list of the tools you pay for and the workflows around them. Sanitised exports are enough.

Why is the Fit Call free?

The 15 to 20 minute Fit Call is a technical discussion to verify whether your stack has pieces worth reviewing before anyone spends money. If we cannot help, we tell you immediately.

What happens after a Pilot is completed?

You receive the complete source code, deployment scripts, and operational runbooks so your team can maintain it without us. Optional Monthly Engineering Plans are available if you want ongoing senior engineering support.

Send us the tools you pay for.

We will tell you, in writing, what to keep, replace or build.
