Gounaki had worked with many artists even before her Popstars debut. She worked with Henning Wehland on his voice for his bands' recordings
Fly Eyes of his band
H-Blockx. After that Gounaki coached, arranged and produced the vocals of
Sandra Nasic, singer of the band
Guano Apes for ''Don't Give Me Names
and Walking on a Thin Line'' and was their steady tour coach and friend during their worldwide tours ( 1998–2002). In 2001, Gounaki became the vocal coach of the German TV show
Popstars. Her work helped the winning band
Bro'Sis selling over 1,500,000 copies of their debut album
Never Forget within three days. Later, she extended her work to different countries. In 2003, she moved to
Athens to become the vocal coach of the Greek version of Popstars and to work on the vocal-production of the winning band
Hi-5. During that time, she also worked on the German Popstars show, which took place in
Orlando, Florida US and created the two bands
Preluders and
Overground. After finishing that production, Gounaki went to Greece to arrange and to produce the Christmas CD of Hi-5, ''Mia Nihta San K'iafti''. After this, Gounaki was one of the judges on the Greek TV Show
Eurostars. The show was won by Apostolos Psihraimis who was supposed to represent the country in the
Eurovision Song Contest 2004. However,
ERT internally chose superstar
Sakis Rouvas and sent him to the Eurovision Song Contest in Istanbul, where Rouvas finished in third place, equalling Greece's best result up to that point. When she returned to Germany, Gounaki coached, arranged and recorded the new Popstars band Nu Pagadi. Gounaki cooperates with music producers and musicians such as
Greg Manning,
Toni Cottura or
Marc Mozart,
Lou Bega,
T.M.Stevens, Leslie Mandoki,
Uwe Fahrenkrog-Petersen, Thorsten Brötzmann or Peter Ries and works for major record companies like
Sony BMG or
Universal Music. However, she took a break for nine months to spend more time with her family. In October 2005, Gounaki published a book called
Singen? Kann jeder! (Everyone can sing), which she had written while she was on hiatus. The following month she took up studies at the
University of Munich to study architecture. Together with German
Pop Idol Alexander Klaws and German singer
Jeanette Biedermann, Gounaki returned to television with the show
Beste Stimme gesucht (Best voice wanted) on
KI.KA, a German TV channel for children. The show scouted for children with a talent for singing. Gounaki also worked very closely with Jeanette Biedermann during her
Bad Girls Club Tour 2006 as her voice coach. Her next TV project as vocal coach and a vocal-producer was a Swiss audition show called Musicstar in winter 2006/07 on SF1. ==TV==
