Solution

AI integration and modernisation of existing applications

AI delivers value where it accesses your own data: documents, product catalogues, customer cases. That requires a modern, well-integrated application landscape. We integrate AI functions into existing systems and modernise legacy applications that stand in the way.

Starting point

With cleanly connected data, AI delivers real value

The bottleneck is rarely the model; it is scattered data and legacy applications without interfaces. If you want to use AI, you first need to know where the data sits and how it can be accessed securely.

That is why AI integration and modernisation belong together: only a clean, connected application makes AI functions reliable.

Typical signs

  1. Staff search through large document collections by hand.
  2. The shop search only finds products when they are spelled exactly.
  3. A legacy application can hardly be extended or secured any more.
  4. Contracts are printed, signed and scanned back in.

Scope of services

From data preparation to AI search, we implement everything

  • AI search in documents

    Semantic search across internal document collections based on Google Gemini and Vertex AI, as in our own product DocuSearch.

  • AI search in the shop

    Customers find products by describing them in natural language instead of using exact terms.

  • Electronic signature under eIDAS

    Experience from our own signature platform MySign: we integrate eIDAS-compliant signatures into CRM processes.

  • Replacing legacy applications

    Refactoring and gradual migration to microservices, without interrupting ongoing operations.

  • Cloud migration

    On Azure, AWS, Google Cloud or with Infomaniak in Switzerland.

  • Data protection and security

    Hosting location, access rights and data flows are defined and documented before implementation.

Operation

After go-live, we keep running your solution

Maintenance, security updates and further development after go-live, hosting in Switzerland (Infomaniak) or in the EU, developed in our development centre, certified to ISO 9001, 14001, 27001 and 45001. We build nothing that we would not also run ourselves.

  • ISO27001ISO 27001: Information security
  • ISO9001ISO 9001: Quality management
  • ISO14001ISO 14001: Environmental management
  • ISO45001ISO 45001: Occupational health and safety

Approach

From the first conversation to operation in four steps

  1. Analysis

    We record use cases, data sources and data protection requirements.

  2. Architecture

    We define the model, hosting and interfaces and break legacy applications down into stages.

  3. Implementation

    We start with a clearly defined use case and measure it by its actual benefit.

  4. Operation

    We continuously maintain and develop models, interfaces and infrastructure.

Customer portal and cloud migration for an energy supplier

2channels on one platform: self-service portal and app, connected to SAP and Dynamics

  1. Problem

    The customer portal was based on a legacy PHP application that could hardly be extended any more. Self-service for web and app was required.

  2. Solution

    Java microservices on Azure with Kubernetes replace the legacy application and connect SAP and Microsoft Dynamics. Content comes from Adobe Experience Manager.

  4. Result

    Customers handle onboarding, invoices and payment themselves, on the web and in the app.

FAQ

Frequently asked questions

Mainly Google Gemini via Vertex AI. Which model fits depends on the use case, the hosting location and your data protection requirements.

We define and document the hosting location, access rights and data flows before implementation. Our development centre is certified to ISO 9001, 14001, 27001 and 45001, and we take into account the requirements of the revised Swiss Federal Act on Data Protection.

In stages: functions are moved to new services one after another while the legacy application keeps running. This is how the REEA Group replaced the legacy PHP application behind an energy utility's customer portal with Java microservices on Azure.

An electronic signature under the EU eIDAS Regulation. Our experience with it comes from the REEA Group's own signature platform. On this basis we integrate signatures into CRM processes so that contracts are signed without switching media. We work out with you which signature level your contracts require.

With a clearly defined use case for which the data already exists, such as search in documents or in the shop. The AI potential analysis shows which case is suitable as a starting point.
