[ The challenge ]

Your business doesn't run like off-the-shelf software.

Spreadsheets, emails, shared files, a patchwork of tools, manual re-entry…

A single application.

When your existing tools no longer fit the way you're organised, custom business software brings all your processes together in a single application.

We design the solution around your real-world constraints.

[ Custom-built ]

Software designed around the way you work, not the other way around.

We build software for every kind of process, from the simplest to the most specific. Each application is designed around your business rules, your approval workflows and the way your teams work.

Operations management

Bring your teams' day-to-day operations together in one place.

Administration

Automate administrative tasks and approval workflows.

Case management

Keep documents, information, statuses, history and actions in one place.

Scheduling

Manage resources, availability, field interventions and deadlines.

Activity tracking

Give every team a clear view of its activity.

Back-office

Manage your users, data, content, rules and settings from a single interface.

Replace the software that forces its way of working on your teams!

We digitise as many of your own business processes as needed: approval workflows, business calculations, regulatory tracking, etc.

[ Growth ]

Software that grows with your business and its needs.

We design architectures that can evolve with the changing needs of your business.

You can start with a focused scope, then add new modules step by step.

  1. Phase 1

    A first functional scope that addresses your most pressing needs.

  2. Phase 2

    Connection to your existing tools and process automation.

  3. Phase 3

    New modules, users, sites or entities added as you grow.

  4. Phase 4

    Fine-tuning, maintenance and continuous improvement.

[ Workflows ]

We turn your processes into smart, secure workflows.

Your software can automate each step of a process, however complex it may be.

Example

Each step can include:

  1. Request
  2. Check
    • Business rules
    • Conditions
  3. Approval
    • Approvals
    • Signatures
    • Human input
  4. Processing
    • API calls
    • AI automations
  5. Notification
    • Notifications
  6. Archiving
    • Documents

[ Back-office ]

We build back-offices that are easy to pick up.

We build admin interfaces tailored to your needs, reliable day to day and designed for your teams.

Among other things, you can manage:

  • Users
  • Roles and permissions
  • Business data
  • Documents
  • Workflows
  • Statuses
  • Notifications
  • Settings
  • History logs
  • Dashboards
  • Exports
  • Imports
  • Business rules

Every feature is designed around the way your organisation works.

[ Integrations ]

We connect your software to your existing systems.

Your business software can become the central hub of your information system.

We integrate the tools you already use:

Your business software

  • ERP
  • CRM
  • Accounting software
  • HR tools
  • Business software
  • Databases
  • APIs
  • SaaS services
  • In‑house systems
  • Connected devices

When standard integrations fall short, we build the APIs and connectors you need.

[ Built-in AI ]

We add intelligence to your business software.

AI can be built in wherever it delivers real value.

For example:

  • Automatic document classification

    Invoices, contracts and delivery notes sorted as soon as they arrive.

  • Data extraction

    Amounts, dates and references read from PDFs and scans.

  • Intelligent search

    A record found by asking in plain language.

  • Report generation

    A service report drafted from field notes.

  • Email processing

    Incoming requests read, qualified and attached to the right record.

  • Decision support

    The relevant information gathered when a request needs approval.

  • Anomaly detection

    Duplicates, amount discrepancies and unusual entries flagged.

  • Internal assistants

    An assistant that answers your teams from your own procedures.

  • Workflow automation

    Steps chained with no re-entry, with human sign-off when needed.

AI becomes a feature of your application, not a standalone tool.

Have an AI use case that isn't listed here?

These use cases are only examples.

We build AI in wherever it saves your teams time: assistants and agents, image analysis, forecasting, schedule optimisation, etc.
