The verdict
If your company already runs on Webex or Cisco and you organise hybrid conferences with several tracks, pick Webex Events. If your events are a marketing or education programme that mixes webinars, on-demand content and some in-person sessions, pick BigMarker.
For a small team, both may be more platform than you need. Ask each for a live demo and a written quote that reflects your attendee numbers, formats and events a year. Webex Events may be bundled in some Webex Suite agreements, so check yours. Confirm that your CRM is supported and how fields map before you commit.
