There is a diverse group of passionate and very successful entrepreneurs creating the products and services that drive the WordPress economy. PressNomics is a 3 day event for these folks to collaborate, learn, and relax.
There have been 5 events, the most recent in April 2017, which have brought together the best and brightest in the WordPress business community. These events have also raised over $40k for various charities, but primarily for childhood cancer research. The event is hosted by Pagely and supported by commercial entities in the WordPress ecosystem.
Simply: The best unofficial WordPress conference ever.
