https://www.futurefonts.xyz/ is a type foundry where type designers sell fonts in progress.

The first release of a font has the cheapest price and the final release has the final price. However, by buying any previous release you also get access to the final release. So the sooner you believe in a designer, the cheaper it is.

I also like the font that they use for their website: Covik Sans Mono by James Edmondson
