Suitors, Inc.

 was a business run by Iris Wildthyme, who was actually working for Madame Binky. Suitors, Inc. manufactured robots known as Suitors, which were part of a plan to capture elderly human women and bring them to Pussyworld.

The original Suitors were identical in appearance to the Fourth Doctor and were programmed not only for housework but also for "wooing and courting and...what not", according to Maude. There was also a version of Suitor that resembled the Third Doctor and was programmed for fighting.

The Fourth Doctor, Romana I and K9 Mark II investigated Suitors, Inc. Sarah Jane Smith and Harry Sullivan also investigated the business. (PROSE: Suitors, Inc.)
