Kadrion Studio

Custom software, built with product discipline.

We design focused business applications, B2B platforms, automations, and integrations for organizations with a clear problem and the means to solve it properly.

Present a projectOne client project at a time

An independent software studio

K / STUDIO

The discipline of a product company, applied to your project.

Studio is a complementary Kadrion activity, not a general-purpose agency. We take on one client project at a time, and only when the problem, scope, budget, and working relationship match our expertise.

A request is reviewed before any proposal. Sending one is neither an accepted order nor a quote.

Three ways to work together

From a sound decision to a dependable solution.

Indicative starting points. VAT not applicable, article 293 B of the French General Tax Code (CGI). Final scope and price are agreed after review.

  1. 01

    Technical audit and written scoping

    A structured assessment before committing to a build.

    €1,500–€3,000

    • Review of the need, constraints, and existing setup
    • Architecture, risks, stages, and estimate
    • A clear, actionable written deliverable

  2. 02

    Custom solution development

    A defined, fixed-price build with explicit acceptance criteria.

    From €7,500

    • Business applications, portals, and B2B SaaS
    • Automations and integrations
    • Agreed scope and acceptance criteria

  3. 03

    Optional maintenance

    Ongoing corrections and small improvements within an agreed allowance.

    €500–€1,500 / month

    • Corrections and minor improvements
    • Contractually agreed monthly allowance
    • Hosting, monitoring, and urgent work priced separately

A good fit

  • A business application replacing a fragile manual process
  • A customer, partner, or member portal
  • A focused B2B SaaS product
  • Automation or integration between existing systems
  • A team with a clear outcome, budget, and decision-maker

Usually not a fit

  • An undefined idea looking for automatic pricing
  • A build below the stated starting budget (an audit and written scoping remain possible)
  • Staff augmentation or permanent on-site presence
  • A build that depends on constant meetings
  • An urgent rescue without time to understand the system

How an engagement works

Clear decisions, mostly in writing.

  1. 01

    Qualification

    You describe the problem, expected outcome, context, timing, and budget. We assess whether the project fits Kadrion Studio.

  2. 02

    Scope and proposal

    When the fit is sound, we clarify the boundaries, risks, deliverables, acceptance criteria, schedule, and fixed price.

  3. 03

    Build and handover

    Work progresses through documented checkpoints. Delivery includes the agreed solution and the knowledge needed to operate it.
