If I remember correctly, presenters will get an email with instructions for the presentation and it has links to some templates. For references, I think you can use any of the previous discovery summit presentations, for reference purposes I would try to use fairly new presentations.
What JMP (+ steering committee) is looking for is explained on the discovery summit's call for content pages. For example call for content for Europe 2027 is open, Discovery Summit Europe 2027 - Call for Content
Ah, ok, got it ... thanks a lot for pointing this out to me
