Experts in IT and data security since 1992
mantau is our latest development at EXEC IT Solutions GmbH. We designed the group manager primarily for the digital networking of groups in non-profit organisations.
For more than 30 years, we have specialised in the development of secure solutions in the areas of risk management, fraud prevention, business processes, and encrypted data transmission and communication.
Well-known credit institutions as well as large, international telecommunications companies trust us. And we now use our know-how and our techniques for mantau as well.
Non-profit - a cause close to our hearts
It is a matter close to our hearts to support the cooperation of predominantly volunteer-based organisations with our current digital possibilities. Our aim is not only to make work easier in terms of communication and organisation. The use of modern tools can also make voluntary work and membership more attractive in general.
Our team benefits from many years of personal experience in voluntary work gained in various associations, initiatives, and church organisations.
Our experience with the collaboration tool "Cocuun" and its practical applications with customers in various organisations additionally contributed to the development of mantau.
The team behind mantau - and contacts
mantau is just the name. But one for an extraordinary app development. Behind it are people, experts from EXEC IT Solutions GmbH.
Together, we have collected the wishes and needs of various non-profit organisations, gathered experience and knowledge, forged ideas, designed and finally coded. And we did it with a lot of heart and soul! Together we continue to work with full commitment to constantly improve mantau for you.

Satisfied customers of the product generation Cocuun
mantau is brand new: concept, user experience, design, functions, technology. But the idea is based on our Cocuun solution, which is well established in the market. After five years, it was necessary to create a new product generation, to incorporate all experiences and customer requirements - and to develop it on a new, modern and powerful technological platform that would make us independent of third-party development technologies. We called the project forward-looking "mantau", as in "let's go"!
The mantau team is co-organiser of the
Stuttgart Non-Profit Forum (SNPF)
We have been actively involved in the organisation of the SNPF since 2020.
The Stuttgart Non-Profit Forum has set itself the task of being a networking, information and help platform for those responsible, decision-makers and advisors from non-profit organisations in the areas of organisation, law and taxes. At face-to-face events, online webinars, newsletters and blogs, NPOs receive important information, help and tips from experts.
Within this framework, we have - in addition to the state of Baden-Württemberg - also funded, for example, an extensive study by the SNPF that examined the "future viability of non-profit organisations".
There for you in the West and East.
EXEC IT Solutions GmbH has its headquarters in Rhineland-Palatinate - and an office in Berlin. So we are also happy to be there for you on site.
