IBM Plex is an open source typeface superfamily conceptually designed and developed by Mike Abbink at IBM in collaboration with Bold Monday to reflect the design principles of IBM and to be used for all brand material across the company internationally. Plex replaces Helvetica as the IBM corporate typeface after more than fifty years, freeing the company from extensive license payments in the process. Version 1.0 of the font family had four typefaces, each with 8 weights (Thin, Extra Light, Light, Regular, Text, Medium, Semi-bold, Bold) and true italics to complement them.
