With Johann Kautsky and Hermann Burghart he established the cooperative enterprise of "Brioschi, Burghart und Kautsky, k.u.k. Hoftheatermaler in Wien", which employed dozens of carpenters, blacksmiths, mechanics and clerks in addition to their painters; among whom were Georg Janny, Leopold Rothaug [de], Ferdinand Brunner and Alfons Mucha. The studio received many orders from abroad as well as locally. Among their regular customers was the Metropolitan Opera in New York.
