I've seen a website called 'This is Five' that used the font so it must be an actual font. Here are any useful details:

- DixonBaxi created the logo
- This is Five used this Unknown font in their logo (Proof: https://www.youtube.com/watch?v=P8GC75g-djA at
- Both Fiver and FiveUSA used the same font and I still don't know it!

Please let me know!
