La Factoría is a Panamanian Reggaeton and Reggae en Español group led by Marlen Romero better known by her stage name Demphra. Initially the group was formed by Marlen Romero (Demphra), Johanna Mendoza (Joycee), Edgardo Miranda (MC Joe) and Pablo Maestre (DJ Pablito). Eventually Joycee, Joey Montana and DJ Pablito left the group, however, Demphra decided to carry on with the project.

In 1999 Demphra joined Panama Music where she launched her first solo album, "La Willa Demphra". The disc was a complete success in her home country Panama including songs as: “El Muslo”, “Tilin Tilin”, “Ush”, among others.
