Happy Anniversary Digital Systems 4.0!

5 years ago in the beautiful city of Plovdiv a new company was born.

The founders had a dream and they had the drive. They knew how to build an outstanding team and lead them on challenging journeys. Even more importantly, they knew how to collaborate and become a trusted partner.

With a few completed projects under our belt and a few more ongoing right now, we have plenty of ideas for the future.

Thanks to all our friends and collaborators for the support over the last five years!   Наздраве!

Cheers to the next 5 years!

Goodbye MobiSpacers!

For those of you who followed our MobiSpaces journey in the past 3 years, we would like to share with you that our project work has now been completed.  The final review on 16 October 2025 in Genoa presented us with an opportunity to highlight all our project achievements which could benefit thousands of citizens as well as researchers and organisations in big numbers.

Thank you project partners for the collaborative work with our DS4 team.  And thank you Matteo Falsetta for your vision, leadership and support.  Throughout the project you were encouraging us to ‘keep pushing’; at the end of the project your message to us was no different:  

‘And remember … KEEP PUSHING … always!!!’

Promise Matteo, we will.  And we know that you will too.

We also know how to celebrate our achievements as the photo from the recent Impact event in Rome shows below 🙂

Until we meet again MobiSpacers!

MobiSpaces Impact Event: Advancing European Mobility Data Innovation – Rome – 23 June 2025

Last week the DS4 team had the pleasure to attend the MobiSpaces Impact Event: Advancing European Mobility Data Innovation held in the beautiful building Spazio Europa in Rome.

It was a wonderful opportunity to take part in this final event which presented and demonstrated the innovations developed during the lifetime of the project; their results empowered 5 real life scenarios including smart cities, transportation systems and maritime operations.

Technical and use cases partners engaged in fruitful discussions with other leaders and researchers in the field of data-driven innovations including AI, data spaces and sustainable transport.

The photos below show Petia in action early in the morning getting ready to meet and greet the participants at the registration desk.

Photos also show Zhilber networking with the other fellow participants; that included smiling in front of the cameras of course 🙂
