Zlatin Tsvetkov
Zlatin Tsvetkov is the founder of ShiZi Improv Theater, the premiere longform improv theater in Sofia, Bulgaria. A pioneer of the Bulgarian improv scene, he co-founded the country’s first improv company and took part in Sofia’s very first improv show back in 2009.
Zlatin graduated the National Academy for Theatre and Film Arts in Sofia in 2005. His career spans over two decades in theater and television, including a three-year run as co-host of a morning show on Bulgarian National Television.
Between 2015 and 2018, Zlatin deepened his improvisational craft in Chicago, completing the 5-week Intensive and 2-week Advanced Intensive at the renowned iO Theater. He also trained with The Annoyance Theater (Chicago) and The Showstoppers (London).
In 2010, Zlatin led Bulgaria’s first-ever improv class and soon after founded the ShiZi Training Center. There, he developed a comprehensive, year-long curriculum spanning 7 levels and advanced groups. The training center now hosts around 160 students, with Zlatin actively teaching five days a week.
Zlatin’s passion for improv lies in its elusive, ephemeral nature — where the process itself is the ultimate goal. He chases the synergy between freedom of expression, deep partner support, and confident stage presence. Equally drawn to the ethereal, interwoven structure of The Harold, the raw truth of theatrical improv, and the over-the-top fun of improv games, Zlatin embraces every facet of the form.
