Expertise

Integration is in our DNA.

Since 2003 our founder Daniel Ivanovic has worked on mission-critical integration platforms, and for more than 18 years with Microsoft BizTalk Server. Today we look after BizTalk environments in production, make them faster and more stable, and replace them when the time comes. Microsoft recommends Azure Logic Apps as the successor. We assess with you whether that path fits and carry out the replacement with containerised .NET services. The same experience goes into our APIs, data platforms and AI-driven processes.

Is it a fit?

When IvaltiCare is the right choice.

We specialise in a small number of topics. This list helps you decide whether a conversation is worthwhile.

What we do

  • Your BizTalk Server is unstable or slow, or nobody in-house knows it well enough any more.
  • BizTalk has to be replaced and you need a decision on which path fits. We give you a neutral assessment of Azure Logic Apps, the path Microsoft recommends, and carry out the replacement with .NET.
  • SAP, EDI partners, online shop, warehouse and in-house applications need to exchange data reliably.
  • A .NET application that has grown over the years needs to be modernised without operations coming to a halt.
  • Your data is spread across systems and you need dashboards or AI features built on it.

What we don't do

  • Workplace IT, networks, printers and telephone systems. An IT support company is the better choice for that.
  • IT security as a stand-alone engagement, such as penetration testing.
  • Web design and online marketing.

About

Lean by design.
Senior by default.

IvaltiCare is deliberately not a corporation. That is precisely what makes us a strong choice for corporations. We combine the dependability of a personally led firm with the reach of a well-coordinated partner network.

Under the leadership of managing director Daniel Ivanovic, we deliver demanding projects independently and with continuous senior-level involvement, from initial concept through to live operation.

Daniel Ivanovic leads every project personally, from the first analysis through to handover. For cover and peak workloads, IvaltiCare works with experienced BizTalk and .NET developers from its own network. That keeps a project staffed during holidays or illness.

The Care in our name is a commitment: we look after things. The systems, the projects, and the people who work with them.

Frequently asked

Good to know.

What does IvaltiCare GmbH do?
IvaltiCare is an IT consultancy based in Leverkusen, Germany. We look after and modernise Microsoft BizTalk Server, connect systems such as SAP, EDI partners, online shops and in-house applications, and develop software in .NET and C#. The company was founded in 2013 and is led by managing director Daniel Ivanovic.
Where is IvaltiCare based, and where do you work?
Our office is at Adolf-Kaschny-Straße 1-5, 51373 Leverkusen, Germany. We work remotely and on-site, mainly in Germany, Austria and Switzerland. In Leverkusen, Cologne, Düsseldorf and Bonn, on-site meetings are possible without a long journey.
How big is IvaltiCare?
IvaltiCare is deliberately small. Daniel Ivanovic leads every project personally, from analysis through to handover. For cover and larger projects we work with experienced BizTalk and .NET developers from our network.
Do you work remotely or on-site?
Both. Depending on the project we work remotely or on-site with you, primarily across the German-speaking region.
What does a first conversation look like?
Non-binding and free of charge. You outline your situation, we assess it and tell you honestly whether and how we can help. You speak directly with the managing director, not a sales funnel.
Do you also replace legacy systems that have grown over the years?
Yes. We modernise integration and software landscapes step by step and during live operation, for example by replacing BizTalk Server with modern .NET, clean APIs and containers.
What size of company do you work with?
From upper mid-market to large enterprise. We are strongest where IT landscapes are demanding, have grown over many years and are business-critical. We support smaller companies on clearly defined integration or development projects.
Do you really use AI in production?
Yes. We integrate AI and language models along concrete business processes and turn data into dashboards that support decisions. Not for its own sake, but for measurable value.
How do you handle confidentiality?
Discretion is standard. Confidential collaboration including NDAs is a matter of course for us, the way major clients expect.
