DevFest Seattle 2026

We're back at Pioneer Square Labs, timed to the Art Walk right after. Three short talks, a panel, and drinks on us. Ana Marini is an education-focused product designer who's been building Lumi, a personal language-learning project, with AI as a design partner. She'll walk through the messy middle of that: what actually happens to your thinking, your judgment, and your creative process when AI becomes part of how you learn and make. Kaelig Deloumeau-Prigent is a design engineering leader who has spent fifteen years building design systems at Shopify, Salesforce, Intuit, and the Financial Times, and co-chairs the W3C Design Tokens Community Group. He'll show how Claude Design, Claude Code, Storybook, and Playwright combine into one agentic workflow that revamps a product's UI from head to toe, design system included, walking through the OpenID Foundation's Conformance Test Suite redesign from user research to the shipped UI. Shuyuan (Sylvia) Ding is a product designer at PenChecks Trust who spent this year going from designer to design engineer, owning both the design and the implementation. She's built a component end to end the way that job works now; AI, engineering collaboration, and QA feedback all in the loop, set against the old model of a detailed handoff and stepping away. Then we open it up. Madison Joslyn moderates a panel with all three presenters, built on your questions. Bring some. Want to present at a future Volume? Get in touch.

Explore the psychology behind AI and its influence on human judgment with Seattle University Marketing Professor Mathew Isaac, Ph.D.

About Event For one night only, the power dynamics are changing. Partners from Madrona, PSL, Foundations, and Tola Capital are stepping out from behind the term sheets and onto the roast stage, where professional comedians will spend the evening reminding them that founders have notes, too. More names to come. No keynotes. No pitch competition. No discussion of market timing, founder-market fit, or why "now is the perfect time." Just investors, comedians, cocktails, and a room full of people who know exactly what a polite rejection email looks like. What to Expect Drinks and networking to start, followed by a live roast of Seattle's venture community. Each investor gets a chance to respond. We expect confidence. We do not expect recovery. Who Should Attend Founders, operators, angels, investors, and anyone who enjoys startup culture enough to laugh at it. Presented By J.P. Morgan, Cooley, and KBF Advisory. We are grateful to all three for making the night possible. Founders get the entertainment, investors get the feedback. Details Thursday, October 8 | 6:00 PM Downtown Seattle Free to attend, venue details provided to approved guests.
