Within

Within (Within Unlimited, Inc.) is a Los Angeles virtual-reality studio founded in 2014 by Chris Milk and Aaron Koblin, both alumni of Google's Data Arts team. Andreessen Horowitz (a16z) led the company's 2016 Series A. Within builds Supernatural, a VR fitness service for Meta Quest headsets that pairs live human coaches with rhythm-mapped workouts set in 360-degree virtual locations; its earlier work spans immersive 360 video and AR (Clouds Over Sidra, Wonderscope). Meta Platforms acquired Within in February 2023 after the FTC's challenge to the deal failed, and it now operates as a Meta studio. Within is a consumer VR product company and publishes no public developer API, OpenAPI, SDK, or developer portal; its primary domain within.com is currently parked. This profile is retained as an a16z portfolio lead with no API surface to enrich.

Within is profiled on the APIs.io network. Tagged areas include Company, Virtual Reality, Fitness, Consumer, and Immersive Media.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
XR & Graphics (XR, 3D, GPU graphics)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
