👍 Presentations should:
- Teach developers about something new in the web + AI ecosystem
- Tell the story of a problem and how it was solved

- Focus on negatives (All the things I hate about Z)
If you’re uncertain if your presentation qualifies for the conference, submit anyway!
How to Submit a Proposal
First, make sure you’re available to speak at the conference. It will be held on June 7 - 8, 2027.
Talk submissions are done as 2 minute videos. Your goal here is not to produce a perfectly executed mini-talk, it is to describe your talk idea informally. What’s the topic? How do you want to approach it? Why is it interesting? We strongly encourage you to include the following elements:
- Introduce yourself - name, company, role
- Tell us what your talk is about - be concise, big picture
- Explain why it’s exciting - and include details (technologies, techniques, etc)
We won’t make the videos public, so no need to worry about random Internet people seeing them. But we feel this is a good opportunity to start building a comfort level with talking about your idea in front of an audience.
Once you’ve recorded your 2-minute video, just upload it to a public but obfuscated place. Some suggestions: Youtube (mark as unlisted), Dropbox, S3, your own web host.
Please double-check your URL in Incoginto mode, any video we can’t reach will not be considered!
Speaker Perks
If we accept your proposal to speak, you’ll receive:
Full VIP ticket to CascadiaJS
Parking or ride share reimbursement
Invite to Friends of Cascadia dinner
Transportation to Seattle (up to $500 for domestic flights, up to $1,000 for international flights)
Lodging for 3 nights
The selection process
- Jan 10 - The CFP closes
- Jan 17 - Review complete
- Jan 18 - Final decisions made, emails sent out
CFP FAQ
What kind of talks are you looking for?
Sometimes it helps to see what kind of talks we’ve selected in the past! Check out our YouTube Page for all the page talks, and feel free to subscribe to get notified when new ones get posted!
Can I submit if I’ve never spoken at a conference before?
This CFP is open to both experienced speakers and folks who have never given a big conference talk. The criteria we will use for evaluating submissions will be the same, and no added weight will be awarded to folks just because they’ve spoken before. Some of the best talks given at past CascadiaJS events have come from folks giving their first conference talk.
I’ve never done a video submission, what am I shooting for?
If you’re still hesitant about the video, here’s a suggestion. Forget recording for now. Stand up, in a place where no one can hear you, and describe your talk idea out loud. When you’re done, start over and do it again, ten times in a row. With a two-minute limit, ten tries only take about 20 minutes. After your tenth try, you may feel much more confident.
Can I submit a proposal in ASL?
If you would like to deliver your talk using American Sign Language, we are here to support you! Once your proposal has been accepted, we will work with you to figure out the best way to make sure your talk is delivered appropriately to folks in our audience who don’t understand ASL.
For the purposes of the CFP, please record the 2-minute video using ASL and include an attached transcript. Our Talk Review Committee will use both the video and the transcript to evaluate your proposal.

It’s got everything — a dedicated fan base of 10+ years, close family vibes, long held traditions (the best karaoke!), sublime locale, and a flair for the atypical/creative conf sessions.
Def apply + attend! https://t.co/yqrEbh0icL
The reason why @CascadiaJS is one of my favorite conferences is because you can truly feel the passion and care that everyone puts into it. There's a real sense of community, it's amazing 🙌👏💜
