Six areas. One architecture.

We build business-critical systems, demanding integrations, data platforms and fine-tuned open-source models on your own infrastructure. Every part is designed to carry the others, and one lead architect answers for the delivery of each.

  1. Custom ERP, CRM and operations systems

    Internal systems for sales, quoting, order-to-delivery chains, production and warehouse control and field work. We replace scattered spreadsheets and rigid off-the-shelf software with one clear system.

  2. Custom AI, fine-tuned models and your own infrastructure

    We train and fine-tune open-source language models on your own data and rules. We deploy AI agents, internal knowledge search (RAG) and document automation directly on your own infrastructure (on-prem or private cloud), with full ownership of your data.

    Example view: the AI agent suggests, a person approves.

  3. Demanding API integrations and finance automation

    Two-way interfaces between CRM, ERP, online stores and back-end systems. We also build automated reconciliation and invoicing pipelines for payments (for example Stripe, card terminals and platform sales) and for accounting systems (Fennoa, Easor, Procountor).

  4. Data architecture, analytics and management views

    Automated data pipelines, central databases and clear views for management, sales and finance. We bring the data of different systems together so that decisions rest on the real figures.

From a review to a long partnership.

Every engagement starts from a written scope and price. You can start with a defined review or the first delivery phase, without a heavy commitment.

  1. Architecture and systems audit

    A tightly scoped review, architecture plan or critical fix when the current system holds growth back or a major system decision is ahead.

    Scope and price: A fixed price or an agreed cap on hours before work starts.

  2. Phased system delivery

    A new custom system, a replacement for old software, or an integration and AI project, delivered in controlled, tested phases.

    Scope and price: A fixed price per phase against a written scope. Each phase is accepted into production before the next.

  3. Support and ongoing development

    A long-term technical partnership for a system in production: monitoring, security, updates and new features at an agreed service level.

    Scope and price: A predictable monthly fee at an agreed service level (SLA), or a development allowance.
