Services

When an off-the-shelf product won't do, we build it. From diagnosis to a system in production, with the same engineering as our products.

Custom software

Systems built around the way your company works, not the other way around.

Who it's for

Companies with their own process that spreadsheets, generic systems or ready-made tools can't handle.

What we deliver

  • Web systems and portals, internal or for your customers
  • Dashboards and tools for day-to-day operations
  • APIs and back ends for apps and integrations
  • Migration from spreadsheets and legacy systems to something maintainable
  • Deployment, monitoring and support for what we deliver

Integrations and AI automation

Your systems talking to each other, and repetitive routines off your team's plate.

Who it's for

Teams that retype data between systems, depend on repetitive manual tasks or want to use AI with their own company data.

What we deliver

  • Integrations between ERPs, CRMs, e-commerce and internal systems via API
  • Automated routines: imports, reconciliations, reports and notifications
  • AI agents that look up and prepare work with your data, with human confirmation
  • MCP servers to connect your systems to AI assistants
  • Webhooks and queues for processes that can't fail silently

How a project runs

  1. 01

    Conversation and diagnosis

    We understand the problem, the process and the systems you already have.

  2. 02

    Proposal with a fixed scope

    What will be delivered, in what order and what is left out, in writing.

  3. 03

    Short deliveries

    Every stage ends with something working that you can test.

  4. 04

    Production and evolution

    We ship it, monitor it and keep evolving it if it makes sense.

We don't sell ready-made packages or list prices: every proposal starts from the diagnosis.
