Kate Sieker with yesAZ and Phoenix Startup Week

PHX Startup Week is a grassroots event led by #yesphx community members and facilitated by the yesAZ foundation. Organizers and speakers contribute on a volunteer basis, and all revenue from ticket purchases and sponsorships goes directly to hosting the event.
PHX Startup Week began in 2014 and quickly became Arizona’s largest entrepreneurial event. The week is packed with informative, inspirational speaker sessions and limitless networking opportunities for startup founders, teams, investors, and supporters.
Our goal is to collaboratively accelerate Phoenix’s diverse entrepreneurial hub and ensure all innovation and ideas thrive by bringing voices from all corners of the metro together to connect, learn, accelerate and empower.
