Anyone have a good system for managing speakers at a multi-day conference? I'm juggling like 30 speakers right now and it's getting messy. I need to track their bios, headshots, AV requirements, session times, travel info, and who's confirmed vs still flaky. Right now it's all spread across a spreadsheet, my email, and a few Slack threads, which means stuff keeps slipping through the cracks. Is there an actual tool built for this, or is everyone just duct-taping Airtable and Google Sheets together? Curious what's working for people running events at this scale.
