Our History

The beginning of the adventure
The founding of ALTER SOLUTIONS originated with Louis and Mathieu in a small office in Versailles. The premises quickly outgrew their space, as did the team, capitalising on the exceptional and historic working environment hosted by Versailles.
Our Digital business unit
Our digital activities continued to gather momentum, especially in IT development. The challenges and implications associated with the digital transformation of businesses were on the rise, which is why this business unit was created.
Our Cyber business unit
Aware of the risks arising from this digital transformation and fascinated by defensive security, it was an obvious choice to create this business unit. It quickly gained momentum in France.
A European aspiration...
Our European adventure kicked off with the opening of two subsidiaries: ALTER SOLUTIONS Portugal, with an office in Lisbon, and ALTER SOLUTIONS Benelux, with an office in Brussels. At the same time, a Nearshore Development Center was created at our facilities in Portugal.
...that gathered pace
We pursued our European expansion with the inauguration of offices in Düsseldorf, Germany. At the same time, a Nearshore Development Centre was set up at our premises in Portugal.
Growth in Portugal
To be even more accessible for our customers, we opened a new office in the North of Portugal, in Oporto.
Proud to be Europeans!
This time, we set out to conquer Warsaw with ALTER SOLUTIONS Polska and Marta’s teams. And we set up new offices in Germany and Portugal.
New offices?
Absolutely! First of all in Spain, with the opening of the new Alter Solutions office in Madrid, but also our first office in the African Continent, in Morocco. And have we mentioned Berlin? What a year!
Part of the act digital group
In 2022 Alter Solutions also became part of act digital Group, a digital consulting company with over 20 years experience, and offices in the USA, Brazil, Canada and Serbia.
