Karmik

From a Weezevent page to a real management tool

Context

Karmik was operating on a generic Weezevent page with no branded website: practitioners using Weezevent to manage bookings, participants had a non-branded experience, no way to control the brand message or user journey.

Challenge: Build a complete custom platform that replaced Weezevent and created the branded booking experience practitioners wanted. The solution needed smooth booking flow, automated payments and emails, and a back-office for independent management.

Results

• Professional brand presence : Branded booking experience replacing generic Weezevent
• Weezevent replaced : Complete custom platform now managing all sessions and payments
• Faster bookings : Performance-optimized site converts better than previous solution
• Independent operations : Practitioners manage sessions and content without technical help
• Local visibility : Ranking on wellness + location queries in Belgium
