Services

Build a product end to end, or advise a team on its agent-native architecture.

Build

The six lifecycle phases. We take the product from idea to production, then keep it running.

01

Discovery

Frame the product before the first line of code, so the budget builds instead of correcting.

Deliverable
A scoping document: scope, user journeys, technical risks and a detailed estimate.
Typical duration
2 to 3 weeks
From
€3,500per project
Service details
02

Product design

An interface that holds together, carried by a design system your developers can keep alive without us.

Deliverable
A design system delivered as code — tokens, components, states — and the screens that use it.
Typical duration
3 to 5 weeks
From
€6,000per project
Service details
03

Web development

A fast web application that holds up over time, with the tests and delivery chain to match.

Deliverable
An application deployed across three environments, with its tests and operations documentation.
Typical duration
6 to 12 weeks
From
€12,000per project
Service details
04

Mobile development

An iOS and Android app from a single codebase, published on both stores.

Deliverable
An app published on the App Store and Play Store, with its release pipeline automated.
Typical duration
8 to 14 weeks
From
€15,000per project
Service details
05

Infrastructure & security

Infrastructure described as code, and Zero Trust access that does not rest on a text message.

Deliverable
Infrastructure reproducible from the repository, and admin access with no shared password.
Typical duration
3 to 6 weeks
From
€8,000per project
Service details
06

Maintenance & evolution

A product kept current, watched and fixed, with someone who answers when it breaks.

Deliverable
A monthly engagement: fixes, security updates and evolutions, with a written response time.
Typical duration
Monthly engagement, no minimum term
From
€1,500per month
Service details

Advise

On a product that already exists. We deliver an audit and a migration plan, not an application.

01

Agent-Native Architecture Advisory

Make an existing product agent-operable without rewriting it — and without opening more than it should.

Deliverable
An audit of what exists and a staged migration plan, each stage shippable on its own.
Typical duration
2 to 4 weeks
From
€9,000per project
