Rival, a startup that develops technology to enable millions of users to create and share 3D content, has come out of stealth and announced it has raised a $4.2 million pre-seed round, led by Speedinvest, with participation from New Renaissance Ventures and high-profile angels.

Rival has created a platform that allows users to browse through immersive 3D short-form content in their spatial computing headset, in a similar fashion to how TikTok or Instagram Reels work with conventional videos.
