Flatiron BID and General Assembly are offering free tech classes for three Tuesdays this summer, beginning July 30.

Classes include an Intro to the NYC Startup Community, The Art of the Pitch and Intro to Google Analytics.

The first class will refresh newcomers to the startup scene on the exciting tech world in New York City, including people, companies, blogs and incubators. The second class teaches participants how to effectively sell a product, and the last class focuses on understanding Google Analytics.

All classes are free, but registration is required. Space is limited.
