Fall Spotlight 2025

The new HubSpot features are here!

HubSpot has always had one clear strength: it combines marketing, sales, service, and data in one platform. With the 2025 Fall Spotlights, this proven foundation is being consistently expanded. New features deepen integration, automate even more data work, and—most importantly—give AI the complete context it needs. The result: AI that is finally truly smart—because it works with complete, linked data.

For me, a team has to be like my current one: you benefit from each other. It's not about hierarchies. I appreciate it when you can get actively involved, when you pull together with motivated, helpful people and look in the same direction. That's what I've found here.

I have the chance to develop further here. In the beginning, for example, I also worked in accounting and administration. When I wanted to work in fewer different areas and focus purely on project management, I communicated this to Thorsten and Monika, the management. My wish was heard! - I really appreciate that.
Katharina Messmer, Project Manager in the Software Development department

I appreciate Monika and Thorsten as bosses and can fully identify with their values and guidelines. I am also very impressed with HubSpot. We have found a cool system that is really fun! The success of the last few years in particular shows that we are doing the right things. I am proud to be a part of it.
