Descripción del empleo

Fourvenues is a tech platform born from within the entertainment industry, which gives it a first-hand understanding of what venues actually need to run their business. The platform brings everything under one roof: online ticket sales, guest list management, VIP reservations, a fully integrated POS system for the bar and box office, real-time capacity tracking, and a built-in CRM to truly understand your audience. What makes it stand out is how it connects all these touchpoints, from the moment someone buys a ticket to what they spend at the bar, generating cross-referenced data that lets owners see exactly which events perform best, which customer profiles spend the most, which promoters actually deliver, and where money is being left on the table. The result: smarter decisions, less manual work, tighter control over the business, and a smoother experience for both staff and guests.
