01 · How it works
A decentralized conference
Tech Week doesn't happen in a single venue. It's thousands of independent events, hosted by the startups, investors and companies that make up each city's tech community.
- 01
One week in each city
Tech Week comes to Boston, New York, Los Angeles and San Francisco once a year, and each city gets a week of its own.
- 02
Hosted by the community
Every event is planned and run by someone in the community, from panels and dinners to hackathons and happy hours.
