Become a Sponsor
Get in front of Seattle's next generation of founders. Back the builders.
The Opportunity
Seattle is ready
Seattle has the second-largest software engineer talent pool in the US, and the highest college-educated workforce among major American cities.
Thousands of talented engineers at Microsoft, Amazon, Google, and Meta are ready to take the leap and start building their own companies.
The timing is right
- Tech layoffs are pushing people to reconsider their paths
- AI is creating greenfield opportunities and a wave of solopreneurs
- Founders want to plug in, and don't know how
Startup Day is the on-ramp for Seattle's potential startup energy.
400+ Founders and Future Founders
We approve every attendee to ensure the right people are in the room
These people are hard to reach and fragmented. There's no conference, no Slack, no meetup where 400+ serious founders show up in one room. Startup Day is that rare moment when they're open and ready for partners, tools, and support.
