ShowUp.ai: AI that makes your webinar registrants actually show up

I built ShowUp.ai after running webinars for the School Business Manager UK community — a 11,000+ member professional network. Our first webinar: 47 registrants. 5 showed up. That's a 10% attendance rate on a topic our community genuinely needed. I tried everything. Better reminder emails. More posts. Personalised messages. Nothing moved the needle consistently. Then I started treating each registrant like a lead, not a ticket. Instead of one generic reminder, I sent 8 different content types — an insight, a poll, a case study, a thought-provoking question, a clean join link. Each one designed to give them a reason to care, not just remember. Our next webinar: 35% attendance. The one after that: 42%. The difference had nothing to do with the topic or the speaker. It was entirely what happened in the 7 days between registration and the event. I built ShowUp.ai to automate exactly that — so any webinar host can get the same result without spending 3 hours writing reminders every week. Would love feedback from anyone running webinars — what's your current attendance rate and what have you tried?
