How to get the most out of Seattle startup events
- Request your Clarify Horizons seat early. It's free, but there are only 150 seats, approved by request.
- Use the free weekly events. The SWELL's Thursday drop-ins, Startup425 coworking days and AI Tinkerers cost nothing.
- Prepare for the next angel round. Watch the Seattle Angel Conference showcase on 12 November, then apply to the next round.
- Host your own event. Seattle Tech Week and Seattle AI Week let anyone submit an event, a cheap way to get in front of founders and investors.
- Don't plan around old events. The GeekWire Summit, Techstars Seattle and Microsoft Build in Seattle are gone; check the date before you book.
