Our Team

Anne Rab

Anne Rab has been working as an actor, director, and theatre educator since 2010, initially based in Leipzig, Germany. She is part of the leadership team of Momenta, Leipzig’s international festival for improvisation, and is a long-standing member of Theaterturbine.

In 2017, she moved to Vienna, Austria, where she continues to teach, direct, and perform regularly within the Viennese improv community. She also works internationally, teaching, performing, and developing new improvised formats and shows.

Her interest in improvisation began over 15 years ago in a clown ensemble creating stories without words, and this work continues to drive and fascinate her today. She explores non-verbal improvisation and teaches bodywork to actors, improvisers, and anyone interested in discovering new ways of expression.

She also loves to perform with a number of duo partners, including Sarah Arndtz (Heroes), Ursula Anna Baumgartner (Bemme & Melange), and Jim Libby (The Messengers), and is a passionate advocate for greater community awareness within the world of improvisation.

Heyfa discovered improvisation in 2009 and has been exploring it ever since. She trained with Ludi IDF and the Impronautes, while also experimenting with transmask, mime, and clown. After co-founding the troupe Les Kontrefaçons in Paris, she later joined the Capitaines de la BIM in Brussels.

She is particularly passionate about long-form improvisation and performs a wide variety of formats, including DIXIT Impro. One of her core projects is Trouble, a feminist format that holds special significance in her artistic work.

Alongside her performance practice, she is actively involved in shaping the improv community: she is part of the team behind the Wonder Impro Festival in Paris and co-organised Mahdia Improvise in Tunisia.

As a member of the Mediterranean collective Sabir, she brings a strong commitment to cultural diversity and inclusivity into her work. She leads workshops for all levels, focusing on storytelling, status, physical connection, and the professional applications of improvisation.
