Last week, our People&Talent team initiated our participation in the Company Hour event hosted by University to Business - U2B UMFST Targu Mures, in collaboration with Sebastian Pui, who joined as our technical speaker.

Sebastian delivered an interactive workshop on Artificial Intelligence for second- and third-year Computer Science students, sharing real-life examples, practical tools, and insights on how AI is transforming software development.

We’re always happy to connect with students, share knowledge, and support future tech professionals.

principal33 at E-world energy & water 2026

In February 2026, principal33 will be present at E-world energy & water in Essen, one of Europe’s leading events for the energy and utilities sector.

We’re happy to share that our colleague Cristian Tiu, Account Manager at principal33, will represent the company on-site, engaging in conversations around technology, innovation, and collaboration in the energy and utilities ecosystem.

If you’re attending E-world energy & water 2026 and would like to explore collaboration opportunities or discuss how digital acceleration can support your business, you’re welcome to reach out to Cristian Tiu directly to arrange a meeting during the event.

At principal33, we firmly believe that a company’s role goes beyond business: it is about being present when it truly matters.
One year ago, following the tragic consequences of the DANA storm, we made a donation to support the families most affected, as a sign of our solidarity and commitment to the community.
Today, as Spain faces another devastating tragedy due to the train accident, we once again want to express our deepest support and stand alongside all the families and individuals affected.
In the most difficult moments, being there for those who are suffering is not just a gesture, it is a shared responsibility. From everyone at principal33, we send our heartfelt thoughts, support, and strength.

Christmas Activities at principal33!



It has become a lovely tradition for us to come together in the office before Christmas to decorate the tree with colleagues and their little ones.



This year, we added a fun twist with a gift exchange game (a different kind of Secret Santa) and made sure the kids had some sweet surprises waiting for them.



It’s always wonderful to take a break from work and create holiday memories together.



Now, we’re looking forward to Christmas dinners and more moments to celebrate with everyone!
