He was their communications guy.  Still lists himself as an Iconomi employee on his LinkedIn.

Iconomi's communications have sucked ass for quite a while now, and Jaka had not said a single thing in over two months.

Jaka's unannounced departure from the company explains why he hadn't said anything in over two months.

Iconomi's failure to replace Jaka and have somebody in charge of communications explains in part why the team's communication has been fucking horrible.

I wanna know how the conversation went down.  "Hey our comms guy quit.  Should we look for a replacement?"  "Nah, communication is overrated.  I know we promised transparency but fuck it."
