Expertise

One framework, five technical areas.

The framework covers the stack end to end. The studio assembles it around your project: every area combines into a single product, delivered fast and built to measure.

We start with the most costly point of friction. The rest only comes once the first building block has proven its worth.

Let's talk
05 areas
  1. 01.

    Custom business software

    The tool that replaces the shared spreadsheet, double data entry and procedures that only live in one person's head. Designed around how you actually work, not a generic template you have to work around.

    • The data model and business rules are written with you, before the first line of interface.
    • Delivery comes in standalone modules: each one is useful on its own, without waiting for the next.
    • Migrating what you already have (spreadsheets, a previous tool) is prepared, repeatable and checked before the switch.
  2. 02.

    Back office and operations

    Admin interfaces that hold up under daily use: search, bulk editing, roles and permissions, action history, exports. Your teams spend their whole day in them, so they are designed that way.

    • Search, filters and bulk editing built for real day-to-day volumes.
    • Roles and permissions per team, and an action history to know who changed what.
    • File imports and exports run in the background, so a large batch never blocks anyone.
  3. 03.

    Built-in AI agents

    Chat and voice agents connected to your data and your business actions. They do more than answer: they prepare the work, carry out what can be carried out, and report back.

    • The agent calls verified business functions; it does not improvise a query on your database.
    • Permanent deletions and publications are confirmed before they run, and every action is reported.
    • The interface still works by hand: AI speeds up the work without ever holding your business hostage.
  4. 04.

    APIs and integrations

    Your existing tools keep running. We connect them through documented, authenticated APIs instead of rewriting everything, and gradually take over what needs to be taken over.

    • Documented APIs, authenticated by token, with separate rights for each caller.
    • Connecting to the tools already in place comes before any idea of a rewrite.
    • Whatever needs replacing is replaced module by module, with no downtime.
  5. 05.

    Security review and pentesting

    On request, we test the security of your website or application within an agreed scope. The quote is prepared quickly, and every review ends with findings you can act on.

    • Targets, limits and terms of engagement are authorised in writing before any test.
    • The review covers exposed surfaces, configuration, authentication and permissions, with targeted tests suited to your application.
    • You receive a prioritised report with the relevant evidence and recommended fixes.
Cathy

Your site is edited live, with an agent.

Every page of this site can be edited from the page itself, with Cathy, the agent that works alongside the signed-in admin: click a piece of text to fix it, describe a change and watch it land on the page. The tool, the Atelier, is reserved for the team that runs the site. The demo shown here reflects how it really works; it does not run it here.

Cathy's panel and editable fields open on the /services page in the Atelier.

4 étapes

Security review: how it works

A review or a pentest is requested from the contact page. Nothing is tested without a written, authorised scope, and everything ends with a report you can have fixed, by us or by someone else.

  1. 01.

    You describe the target

    From the contact page: the website or application, what worries you, what must not be touched under any circumstances. An address and two lines are enough to get started.

  2. 02.

    We reply with a quote

    The quote states what will be checked and how (configuration and code review, access checks, targeted tests or a pentest), and what is excluded. You know what you are buying before you say yes.

  3. 03.

    We work within the agreed terms

    Targets, limits and terms are authorised in writing before any test. A pentest only takes place on explicit request, within those terms and that scope, never beyond.

  4. 04.

    You receive the report

    Prioritised findings, the relevant evidence, and a recommended fix for each one. It is written to be followed by the team that maintains your tool, whether that is us or not.

The infrastructure carries its own certifications.

Hultra relies on Vercel, Convex and Cloudflare to host, serve and protect your projects. Each one publishes its own attestations: here is what each one actually displays, without crediting anyone with one they do not hold.

Vercel

  • ISO/IEC 27001:2013
  • SOC 2
  • PCI DSS
  • HIPAA
  • GDPR / Data Privacy Framework
  • TISAX
