You can find The Futur's prints here — I think it's the same font they use in their videos.
At first, I thought they were using Futura, but the a
's don't match.
Then, after going through some identifiers, the closest I could get was Adobe Fonts' Neue Haas Grotesk. But Brandon Grotesque — which seems to be a rebranding of Akzidenz Grotesk1 — also seems to be a good fit. Neue Haas Grotesk isn't mentioned in their Typography Manual Video so I suspect it isn't the correct font.
I'm pretty new to design, so if you can mention the tools and techniques I'm lacking in order to identify this font, I would really appreciate it.
1 Which some people told me was also rebranded as Helvetica.
