Promotty is an app that brings together discounts and loyalty cards from local businesses. To grow, it first needed to bring businesses on board, starting with burger restaurants.

Together with the founders, we created UBC (Ultimate Burger Championship), a year-round ranking of burger restaurants across Spain. Restaurants climb through customer votes and events. I designed the brand, the website, and the voting and membership flows inside Promotty's existing app and merchant dashboard.

Role: Product Designer (sole designer) Timeline: December 2025 to June 2026 Result: 70 paying member restaurants across 12 cities in five months

A brand that borrows from combat sports: black, red, wide type and a hexagonal badge for each restaurant.

Voting in one tap. A QR code in the restaurant pre-selects province and venue, so the customer only confirms.

The restaurant profile, designed as a page owners wanted to share: position, awards, featured burgers and locations.

Everything UBC needed to launch and stay active: printed QR materials, social content and event identities.
