Connect with Developers Building the Future of Web and AI

Since 2012, CascadiaJS has brought together developers building the modern web. Rooted in the JavaScript ecosystem and evolving alongside AI, CascadiaJS connects the engineers, tools, and ideas shaping the next generation of software.

CascadiaJS connects sponsors with highly technical developers who evaluate tools, share recommendations, and influence technology decisions at their organizations.

Unlike massive conferences where hundreds of exhibitors compete for passing traffic, CascadiaJS offers a high-trust environment for meaningful conversations. Demonstrate your technology, gather feedback, share expertise, build relationships, and get your products considered when teams make technology decisions.

More face time. Better conversations. High value from every sponsorship dollar.

Testimonials

Onebrief on LinkedIn
What a week at CascadiaJS.

A huge thank you to the CascadiaJS team for putting on such a fantastic event and to everyone who stopped by our booth, attended Jeff Otaño's lightning talk, or connected with us at the networking mixer. It was great to connect with so many thoughtful, curious engineers and sharing what we're building at Onebrief.

A few moments that stuck with us:
⚡Jeff's talk on building AI platforms engineers actually trust sparked some great conversations with people tackling similar challenges in their own organizations
🤖 Great conversations about how teams are using AI and how we’re applying it across our product and engineering organization
🕺 One attendee even brought over a dancing robot they'd built as a side project. It may have been one of the coolest things we saw all week

If we met you in Seattle, or if the conversations above sound interesting to you, we're hiring. Check out our open roles in the comments.
