Netlify @ Barcelona
The Netlify leadership team is in town to meet Barcelona’s AI builders and developers. A live Agent Runners demo from PM Vanessa Ramos, a fireside chat with CTO Dana Lawson and CPO Wade Wegner on where the web goes next when agents do the building, then drinks and a mixer with the whole Netlify crew in Poblenou.
