In a bid to become the go-to avatar company of the metaverse, Ready Player Me has raised a $13 million funding round led by venture capital firm Taavet+Sten.

The company creates tools for developers to sell in-game wearable items expressed as non-fungible tokens (NFTs), adding a layer of interoperability to the bustling virtual fashion space as Nike and others rush in with their metaverse bets.

Ready Player Me’s ultimate goal is for users to be able to maintain a consistent avatar and identity across virtual worlds, serving as a “connective passport for the metaverse,” according to a press release.

The company says it already has over 1,000 companies using its items on their platforms. According to the press release, media conglomerate Warner Brothers, designer fashion company Dior and sportswear brand New Balance have all partnered with the company for future involvement in the metaverse.

“Building a good avatar system takes six months, 12 months of time,” Ready Player Me CEO Timmu Tõke told CoinDesk in an interview. “So we take that pain away from developers by doing the work for them. We want to unify the outer layers of virtual worlds to make for a smoother user experience.”

The funding round included participation from GitHub co-founder Tom Preston-Werner, Konvoy Ventures, Samsung Next Ventures and Tiny VC.
