PLSIC's sponsorship surfaces are the named events and programs the standards body convenes. An underwriting commitment supports a defined surface for a defined period, with named recognition on that surface and nothing more.
This is not ongoing engagement, not a directory listing, and not a standards-input track. Those belong to other PLSIC programs.
Sponsors underwrite. Strategic Partners co-develop. Preferred Vendors sell.
A Sponsor underwrites a specific surface for a defined period in exchange for named recognition on that surface. A Strategic Partner contributes substance over time (curriculum, research collaboration, convening) in exchange for aligned brand surface on what they helped build. A Preferred Vendor is in the operating vendor program: ongoing listing-and-engagement, three-year founding lock, directory presence, and at Elite a standards-input track.
Many Elite Preferred Vendors also sponsor named surfaces. Some Strategic Partners also underwrite. The relationships are named separately on each surface.
