Muller later co-founded, together with ex-Beach Boys Manager and lyricist Jack Rieley, the multi billion dollar internet company JFAX,[2] later renamed to j2 Global (Nasdaq: JCOM), which initially allowed its users to receive fax and voicemail through their email, one of the first unified messaging systems.

Muller released his first solo album under the name J. just after the fall of the Berlin Wall, still under the East-German state record label AMIGA.

The first single's video of the album for the song "Big TV Star" caused some controversy as it portrayed the mainstream media as "Fake News".

The album included collaborations by, among others, Adam Marsland, Roger Joseph Manning Jr. of Jellyfish, Nuno Bettencourt of Extreme, and Jack Rieley of the Beach Boys.

Muller released another solo album as Count Jaye in late 2022 called "You Belong To You" on his label Flasher Factory.

"[11] Aron Gibson of BandRumors wrote about the first Count Jaye album: "Jaye Muller, the charismatic German songwriter, frontman and accidental tech pioneer who shot to fame in the early 90s with his seminal record We Are The Majority, is back..." "Muller, who had made waves across Europe on shows like MTV Europe and who also made a splash on American TV..." "The rocky but Beatlesque sounding songs are “raw and dirty” indeed but are also well crafted.
