1. Dreamforce

#1 Technology Industry Event
Former Vice President Al Gore, Grammy-winner Will.I.Am, and N.B.A. all-star Andre Iguodala walk into a tech conference. That’s not a joke; it’s just a partial slate of speakers on the schedule for Salesforce’s annual gathering, Dreamforce. The event takes over downtown San Francisco each fall with more than 180,000 registrants. (To put that number in perspective, Dreamforce is more populous than the capital of Rhode Island.) In addition to the scheduled trainings and conference speakers, it’s also a prime networking event. At the end of the week, festivities wrap up with a celebratory concert. Past performers include U2, the Foo Fighters, Alicia Keys, and Lenny Kravitz. Next: September 25-28, 2018

3. Apple Worldwide Developers Conference

Some conferences take the bigger-is-better approach; the Apple Worldwide Developers Conference prefers exclusivity, offering admission to software developers chosen annually through a lottery. (Registration typically occurs around March.) In 2018, 6,000 people attended the expo to watch Tim Cook reveal Apple’s latest software updates. After the big reveal, developers move to breakout sessions where they can pepper Apple engineers with questions. Next: June 2019
