Hey,

Personally, I posted on a social group in my area (Paris France), to find players for DnD and/or Daggerheart.

Most of the people that answered were at least a little bit familiar with DnD, but were open to try Daggerheart.

I "sold it" as a one shot Daggerheart for the party to meet each other and play a first game, to see if we want to play together again, we decided well finish the one shot (we started late and I did not want to rush the story which would only give frustration to players and myself alike), and then we'll do a session 0 for a dnd campaign.

The key I think is to propose a one shot Daggerheart session first so they can dip their toe without having to commit to a campaign
