Hi Tudor,
I've seen a lot of variety but in my field, it is quite normal to put just the name and affiliation. Some people put their job title and a logo (or multiple logos) too. Usually this is when the project has been clearly funded by a funding body and they need to say thanks publicly. I've not seen logos at the end of a presentation but I wouldn't think it was weird if someone did it. Usually, I put my name and email address with a 'thank you for listening' on the final slide. Hope that helps!
