Indie Hackers Meetup - Ideas of content

Hello 👋,
With @Vianney we are organising the Indie Hackers meetup in Paris.
I was wondering if you had best practices concerning the program / agenda of the meetup?
Usually do you have one or two speakers presenting something?

Btw if you are in Paris on Nov 15th, feel free to join: https://www.eventbrite.fr/e/billets-paris-indie-hackers-meetup-s01e02-52206423819
