The problem
KaBuM! wanted to build a dedicated hub for Brazilian gamers that would bring competitive play directly to their customer base. Their goal was to give customers a reason to keep coming back and to establish KaBuM! as the home of grassroots esports in Brazil.
Launching KaBuM!GG with API-powered tournaments
KaBuM! is the largest e-commerce platform in Latin America, specializing in tech and gaming products. Esports isn’t new territory for them — they entered the competitive scene in 2013 with their own League of Legends team and have been building credibility with gamers ever since. KaBuM!GG is the next step in that journey: a dedicated gaming arena designed to bring competitive play directly to their customers.KaBuM!GG was built as a fully branded gaming arena on Challengermode, giving their customers a dedicated home for competitive play. Challengermode powers the competition infrastructure: tournaments, ladders, leaderboards, prize automation, and live data. As participation grew, so did the scale of the competitions. Automated prize distribution and on-site player support meant the team could run bigger events without adding headcount.
11% sales lift and 200,000 gamers reached
The numbers tell a clear story. Over twelve months, KaBuM!GG reached more than 200,000 unique gamers and converted nearly 7,000 of them into active competitors. Online store sales rose 11% during active competition periods — a direct signal that engaging customers as players, not just shoppers, drives purchasing intent.KaBuM! ran the full spectrum of competition formats: single-elimination tournaments, ongoing ladders for consistent engagement, and leaderboards that kept players coming back week after week. Each format served a different audience and a different point in the engagement cycle. Together, they created a platform that gave Brazilian gamers a reason to return to KaBuM! even when they weren’t shopping. The 11% sales lift validated the core bet: competitive gaming is a customer acquisition and retention strategy, not just a brand play.
From e-commerce to esports ecosystem
KaBuM!’s esports roots go back to 2013, when they fielded their own League of Legends roster. In 2014, that team did something no Brazilian squad had ever done: they qualified for the League of Legends World Championship. It put Brazilian esports on the global map and cemented KaBuM! as more than a retailer — they were part of the community.KaBuM!GG extends that legacy to the entire customer base. The initiative was built specifically to support and strengthen esports in Brazil, creating a solid community around the brand. The platform gives every KaBuM! customer — not just the pros — a place to compete, improve, and belong. Shoppers become competitors. Competitors become loyal customers. The e-commerce flywheel and the esports ecosystem reinforce each other, and KaBuM! sits at the center of both.
