In 1993 Apteker co-founded Internet Solutions, South Africa’s first Internet service Provider (ISP) in 1993. With thousands of employees, it became one of the country’s most successful post-apartheid businesses, winning numerous technology awards. Apteker has written a number of papers, published both locally and internationally. In February 1994, he presented a paper in San Jose, California, on Distributed Multimedia to the International Society for Optical Engineering. This paper was subsequently published in the SPIE/IEEE Proceedings.

Since 2000, Apteker has been one of the leading independent film producers in South Africa. His films include Material, Tell Me Sweet Something and Cold Harbour. Etc. etc. Despite critical and popular acclaim within South Africa, some of the films have failed to find the wider international acclaim that many feel they deserve. Apteker’s involvement in the South African comedy club scene has led to several comedians appearing in his films, most notably Riaad Moosa, Joey Rasdien and Vincent Ebrahim from the BBC’s The Kumars at No. 42 who appeared in the film Material.

In 2002, Apteker sponsored and produced the successful Laugh Out Loud fundraiser, South Africa’s largest stand-up comedy TV show which raised half a million Rand for the Reach for a Dream foundation.
