Six teams participated in the NPSL Members Cup, formerly known as the NPSL Founders Cup, a competition that ran from August to October 2019 after the conclusion of the regular 2019 NPSL season. It was intended to lead to a new professional league beginning play in the spring of 2020.
Several other clubs were initially announced to be part of the tournament. California United Strikers FC officially announced on Twitter that it had withdrawn from both the Founders Cup and subsequent league on March 1, 2019 and were replaced by Napa Valley 1839 FC on March 7, 2019. On June 27, 2019, Oakland Roots SC announced its intent to join the upcoming National Independent Soccer Association (NISA) in fall 2019, where they joined Cal United. They would therefore be dropping out of the tournament "to focus on NISA as (their) preferred path forward."
When the competition officially re-branded on July 24, 2019, ASC San Diego, Cal FC, FC Arizona, Miami FC, and Miami United FC had been removed, Miami FC joining NISA, while the Michigan Stars FC had been added. On August 15, Chattanooga and Detroit City were both announced to be joining NISA in the spring of 2020. Michigan Stars were also confirmed to be joining NISA on September 21. And New York Cosmos ended up later joining, in 2020.
