Over the past five years, Google has brought top startups from around the world to Silicon Valley to showcase their technology and meet investors and mentors.

The North American Demo Day features startups nominated by North America-based partners in the Google for Entrepreneurs Partner Network.

Teams from 12 North American cities were picked by Google based on proven traction, team strength, sustainability, and growth potential in their market.

Thirteen startups will get to make their pitches in front of top-dollar investors on June 8 at Google Demo Day — an invitation-only event in San Francisco.
