The copyright line in your event footer uses the current year and the Company Name saved in your event settings. HeySummit updates the year automatically.

Company Name and Brand Name are different
Company Name is the formal event company name used in the footer and other event content. If you want a shorter customer-facing name in places such as an email sender label, use the separate Brand Name field in the same Event Settings panel.
