Jacquemus: The awkwardness of these forms indicates that they come from pure geometry, or from a template such as Plaque Découpée Universelle, a stencil system patented by Joseph A. David in 1876. Dries Wiewauters’ PDU is based directly on letters drawn from that stencil. It’s not a match for this sample, but it’s close. See also Garaje and Normal Bold. That said, given that the font seems to lack kerning, it may not have that rigorous a process story. It’s likely a freebie by an amateur.
Braun: This logo is an example of custom lettering, not a typeface. As far as I know, no font was developed before the logo was drawn. (Though perhaps at some point Braun, or someone else, made a typeface based on the logo’s letters.) For available fonts in this style, see Kunst, Refrigerator, and my own WPA Gothic.
Finally, Komu offers a single type family with two variants: flat curves, and round ones, so you can have both styles!
