We aren't scheduling live demos of Luma now. But you can try out most of the functionality of Luma on our website.
You can sign up and create an event on the free plan. You can also see a variety of events and calendars on lu.ma/discover.
Luma Plus is a paid plan that has some improvements over the free plan like zero processing fees, more admins on a calendar, increased sends, and the features listed here lu.ma/pricing. But the vast majority of features are available on the Luma Free plan.
If you'd like more help, you can email us at support@lu.ma.
