Comment by Florian Hardwig on A24 website

That’s a misunderstanding: the A24 logo is custom drawn by Grand Army around 2016. It doesn’t use a font.

Via is a font that was started in 2021/2022 by Jacob Poindexter, based on the A24 logo. He describes it as his “typographic tribute to [his] favorite A24 films”. (I’m linking to an archived snapshot because Jacob’s website is currently inaccessible.)
