SYPHA was founded in 1989 to provide consultancy, research and publishing services for the professional audio, video, broadcast and film industries.

Its founder members, Yasmin Hashmi and Stella Plumbridge, are highly-qualified electronics engineers whose experience of consultancy includes projects involving industry, government and education. Within the media environment, we have experience in writing, commissioning and editing for many leading trade publications, and first began publishing our own specialist equipment guides in 1990.

Having recognised a need in the residential systems industry for those who can understand, explain and apply technology, we responded by launching HiddenWires in 2003, a trade magazine for the home automation industry, which is now owned by the IML Group. In 2013, we expanded in to the building control market with KNXtoday, a trade magazine for KNX home and building control.
