Custom applications with artificial intelligencefor companies that want to grow without growing their structure

Tecnea builds custom web and mobile applications that integrate artificial intelligence into a company's processes: orders, documents, customer service and management control. We have been building them since 2016, from Madrid and Gijón, for companies across Spain, with private AI compliant with the EU AI Act and GDPR. The code developed specifically for each project, and the data, remain the client's property.

Code ownership set out in the contract
Pilot (proof of concept) in 2 to 4 weeks
Private AI, hosted in the European Union

What we build

Applications that do the work, not just describe it

  • B2B portals with chat and voice ordering

    Your customers place orders by speaking or typing, and the system validates them against the real prices, stock and terms in the ERP. Never a figure made up by the AI.

  • Assistants over your company's documentation

    Contracts, case files, manuals and procedures searchable in natural language, with the source of every answer and per-person access control.

  • Automatic reading of invoices, delivery notes and reports

    AI document recognition, validation against the order and posting to your management system, with human review of exceptions.

  • Document generation

    Reports, proposals, legal documents and communications from your data and your templates, reviewed by the responsible person before sending.

  • Dashboards and management control

    Sales, site, production or service data in real time, without asking anyone for a report.

  • Integrations

    ERP, CRM, email, WhatsApp, e-signature and third-party platforms. AI is of little use if it is not connected to where the work happens.

How we build it

From the process to software in production

  1. 1 to 2 weeks

    1. Understand the process

    Who does what, with which data and where time is lost. We define the scope of the pilot and its price.

  2. 2 to 4 weeks

    2. Pilot

    A real application with real users on one process. Deliveries every two weeks and continuous adjustment.

  3. 8 to 12 weeks

    3. Product

    Integrations, permissions, security, training and documentation. EU AI Act and GDPR compliance is built into the design, not added at the end.

  4. monthly

    4. Maintenance and evolution

    Support, improvements and new use cases within the monthly fee, with no per-user licences. The code developed for your company is yours by contract; Tecnea's own components on which it is built remain Tecnea's and are used within the service.

Price

Between €5,000 and €20,000, fixed price per phase

That is the usual range for developing an AI application at Tecnea, excluding VAT, from an application on one process to a complete one integrated with your ERP. Before that, a proof of concept (pilot) from €850 is the first investment: it shows the base of the application on real cases, validates the solution technically and refines the requirements, so the scope of the full project is closed with less uncertainty and less cost. Afterwards, a monthly fee from €250 for the duration of the contract covers the service infrastructure, the AI provider account, maintenance and evolution, with no per-user licences.

  • Proof of concept (pilot): from €850
  • Complete application with integrations: up to €20,000
  • Monthly fee from €250 for the duration of the contract: infrastructure, AI and maintenance

Guarantees

What stays yours, in writing

The questions a demanding buyer would ask before signing, answered in advance:

  • Ownership of the source code, prompts, configurations and documentation developed specifically for your project is set out in the contract, with clear clauses, in your company's favour. Tecnea's own components on which it is built remain Tecnea's and are used within the service.
  • Infrastructure dedicated to your company and the AI provider account, contracted and operated by Tecnea and included in the monthly fee for as long as the contract lasts.
  • Complete technical documentation of the system, delivered with it and kept up to date during the contract.
  • Your data stays yours: hosted in the European Union or in your environment, never used to train third-party models.
  • No lock-in to an AI vendor: the application can switch models without being rebuilt.
  • Intellectual property and exit terms defined in the contract; no per-user licences.

Technology

How it is built

Web and mobile applications with TypeScript and Next.js, PostgreSQL databases, and language models from the main providers hosted in the European Union when personal data is involved, or private models when the data requires it. The application does not depend on one provider: the model can be swapped without rebuilding it. Every model call is logged: what was asked, with which data and what was answered.

Why custom

The solution is not ChatGPT

Generic AI tools do not know your prices, your customers or your processes, and your team ends up copying and pasting company data into them. A custom application integrates AI where the work happens, with your data and under your control. It is the difference between going faster and doing it better.

Why a company earns more with a custom application

Where

Madrid, Gijón and all of Spain

Headquarters in Madrid (Velázquez 27) and an office in Gijón, at the Science and Technology Park. We build remotely for companies across Spain, with in-person meetings in Madrid and Asturias when the project calls for it.

Frequently asked questions

What we get asked before starting

Who owns the application's code?+

Your company's, by contract: ownership of the source code, documentation and data developed specifically for your project is set out in the contract with clear clauses. Tecnea's own components on which it is built remain Tecnea's and are used within the service. There are no per-user licences.

Which artificial intelligence models do you use?+

Whichever solve each task best: models from the main providers hosted in Europe, and private models when the data is sensitive. The application does not depend on one provider and the model can be swapped without rebuilding it.

How much does a custom AI application cost for a company?+

In most cases, between €5,000 and €20,000 excluding VAT, depending on the process and the integrations. We work with a fixed price per phase: the proof of concept (pilot), from €850, is the first investment and we only continue if the result justifies it. Afterwards, a monthly fee from €250 for the duration of the contract covers infrastructure, the AI account and maintenance.

How long does development take?+

The pilot, a proof of concept, is ready to demonstrate two to four weeks after the process is defined; the complete product, in production, eight to twelve.

Does it integrate with my ERP?+

Yes. We integrate with ERPs and management systems from different vendors, via API or file exchange when there is no API. The integration is defined in the diagnosis.

Does the application comply with the EU AI Act and GDPR?+

Yes, and it is documented: register of AI systems, legal basis for processing, data location, transparency towards users and human oversight in the decisions that require it.

Who will work on my project?+

A senior, stable team: the business analysis, documented, drives the development, and the same team maintains the application afterwards. No rotation, no middlemen, and everything documented so the project never depends on a single person.

What if we want to switch providers in three years?+

Yes. The code developed for your company is yours and another provider can continue it, and the application does not depend on a specific AI provider. When the contract ends, the fee stops with the notice set out in the contract; the infrastructure, the AI provider account and Tecnea's components are part of the service and are either replaced or their continuation is agreed, on the terms set out in the contract. There are no per-user licences.

Which application does your company need?

Tell us about the process you want to improve and we will tell you whether an AI application makes sense, what the pilot's scope would be and how long it would take. No commitment.
