A real-world example

Which in-game items should we show this player?

The average game store shows 200+ items but only 3% get meaningful engagement. A game earning $40M in IAP where 80% of revenue comes from 5% of the catalog has massive untapped potential. Generic featured-item rotations ignore that a player who just unlocked a new character class wants complementary gear, not random skins. Personalized stores lift conversion 30-50% but require understanding the intersection of player progression, inventory gaps, and social trends.

How KumoRFM solves this

Graph-learned player intelligence across your entire game ecosystem

Kumo connects players, inventories, the item catalog, and purchase histories into a graph where item affinity propagates through ownership patterns and social influence. It learns that players who own specific item combinations and just reached a new progression tier purchase complementary items at 5x the base rate. The model captures trending items within guilds, seasonal preference shifts, and inventory-gap signals that collaborative filtering alone cannot detect.
