Today we’re excited to announce several new speakers for Seattle 2.0 Startup Day, the one-of-a-kind entrepreneurial boot camp to be presented by GeekWire on Sept. 22 in Bellevue.

And a quick reminder: Early bird rates for the conference end tomorrow, so be sure to grab your tickets now.

This annual event, now in its fourth year, is a must-attend conference for anyone thinking about launching a new company, or looking to improve their existing startup. It’s a chance to learn directly from startup vets — people with extensive experience launching and running their own tech companies, multiple times in some cases.

We’ve already announced speakers including Box CEO Aaron Levie, who just pulled in $125 million in venture capital for the file-sharing and data storage company; and Jordan Weisman, the legendary game designer whose company raised more than $1.8 million on Kickstarter to bring back the classic Shadowrun franchise.

Adam Tratt

New additions to the lineup include Adam Tratt, the CEO of Giant Thinkwell, which just launched the new presentation technology Haiku Deck; Aviel Ginsburg and Adam Schoenfeld of social media analytics company Simply Measured; and entrepreneurial vet Brenda Spoonemore, who is now co-founder and CEO of Dwellable, the vacation rental search site.

They join a roster that includes wireless industry vet Mary Jesse of Ivy Corp.; BigOven‘s bootstrapping Steve Murch; fast-growing zulily‘s Darrell Cavens; and GeekWire chairman Jonathan Sposato, the former Picnik CEO and the only person to have sold two companies to Google.

These startup vets will deliver a series of fast-paced talks — packed full of lessons learned, tips and insights from their own startup experiences. More background on all of these speakers is available on our Startup Day event page.

Aviel Ginsburg

This annual event was started by Marcelo Calbucci of Seattle 2.0 four years ago, quickly becoming a mainstay of the startup scene. GeekWire is proud to carry on the tradition, while putting several new spins on the day — including live versions of two favorite GeekWire features.

The first is Elevator Pitch, inspired by our web video series of the same name. Throughout the morning at Startup Day, a handful of entrepreneurs will pitch their ideas to investor judges, get valuable feedback, and audition for a chance to present to the entire Startup Day audience. (No extra charge but space is extremely limited; choose ticket type “entrepreneur + elevator pitch” when you register).

In the afternoon, we’ll bring you a live version of our Startup Resource Center.  Select attendees can get the answers to everything they wanted to know about finance, law, sales, marketing, PR, team-building, design, user experience, but were afraid to ask. Choose a category and enjoy a 1:1 meeting with best-in-breed advisors. (This is a first-come, first-served perk offered at registration, so don’t hit snooze on that alarm clock or you may miss out).

And to cap the day, we’ll have a big after-party open to all attendees.

More information and registration available here. Wednesday is the last day for early bird rates.
