Get to know us a little better

This is the story of Navvia

We are people passionate about helping companies improve business outcomes. For over a decade, our parent company, Consulting-Portal, has proven this ambition by assisting countless organizations design and implement effective IT and business processes that increase business value.

Passion to help becomes passion to empower. Combining our ITSM success with a desire to simplify process management, we built the first cloud-based process software to aid IT Service Management (ITSM) practitioners. We called it ITOptimizer.

Today, ITOptimizer has evolved and become Navvia. This new name reflects our guiding principle of simplicity, as well as the broader process management capabilities of our product and services beyond ITSM. Derived from the roots "navigate" and "via", it illustrates how Navvia empowers businesses with clear navigation to steer their ships to the desired destinations.


Consulting-Portal is founded by chief Navvians David Mainville and Karl Bietsch. As veterans in service management, they have helped countless organizations implement streamlined processes that meet both business and customer needs.


We release the first iteration of our process modeling tool, which is used by our consultants on large client projects.


We release ITOptimizer as a SaaS-based toolkit designed to assist in developing IT Service Management (ITSM) programs.


Our consultants and developers work closely to add a host of comprehensive features and functionality to ITOptimizer. Our product begins to gain industry recognition, and becomes widely used by industry professionals.


ITOptimizer evolves into Navvia - online software that is robust, intuitive and flexible for managing both IT and business processes.

Now + beyond

Focus on improving Navvia's user interface for increased ease of use. Add more functionality to support full lifecycle management and automation. Nurture the growth of the Navvian community before launching a marketplace where Navvians can develop and exchange apps, plugins, templates, best practices, and more.
