AI is changing how we build and innovate. Nearly 60% of the code our engineers produce is now coauthored with AI—roughly twice the industry average, by our estimate. This isn’t just an efficiency story. It means our teams are shipping faster, iterating more quickly, and delivering more improvements to guests and hosts than we could before. We’re converting AI adoption into real product wins, and we’re just getting started.
The clearest example is customer support. For guests who contact support through our AI Assistant, over 40% of issues are now resolved without a human agent—up from roughly a third in Q4 2025—with significantly faster resolution times. We saw our cost-per-booking decrease about 10% year-over-year in Q1—a meaningful trajectory we expect to continue as we further improve AI customer support this year.

I was recently contemplating opening as many support tickets as possible at these companies, purposefully being difficult so that the case cannot be “solved” by a bot. Then, I’d start automating the creation of these tickets with AI and report back what percentage of my fake tickets were able to fool their AI without human intervention.
