The company behind Decentraland is Metaverse Holdings.
Decentraland is an Ethereum-based 3 Dimensional virtual platform, basically, a Metaverse where you can buy or sell lands/plots.
Decentraland was created by Argentinians Ari Meilich and Esteban Ordano, and has been in development since 2015. When it launched in 2017, parcels of digital land sold for about $20, and mana tokens sold for $0.02. The game’s first map, Genesis City, was made up of 90,601 parcels of land.
