Evessio is an event platform with registration forms, ticketing, onsite check-in, an attendee app, attendee email, and exhibitor tools. It is available on the web and iOS and is made by Evessio, headquartered in Sutton, Surrey, United Kingdom. Its listed theme options vary in how much branding and code customization they allow. Starter applies a customer logo and brand colours to an existing theme and includes Evessio content types, without CSS or JavaScript customization. Custom work allows targeted changes to an existing theme, including CSS adjustments to layout and style and JavaScript behaviour tweaks, within an agreed time budget. Custom theme provides a fully branded theme with extensive CSS and JavaScript changes; typical delivery is listed as 6–8 weeks. Evessio is a paid product and pricing is available on request. These theme choices give event teams options for working with an existing design or specifying more extensive changes alongside the platform's event tools.
