Watch any event,
from any angle
Free-viewpoint playback for any event. The crowd already has the cameras — we turn their footage into an experience you can explore.
Technology
The intermediate representation
between world models and reality
Fusion of Shape-Of-Motion and Test Time Inference. We bridge the gap between diffusion models and physics engines to answer: “How do you represent what is real?”
Volumetric Reconstruction
Real-time volumetric reconstruction from uncontrolled, unsynced phone footage. Multiple perspectives fused into a coherent 4D scene.
Free-Viewpoint Playback
Move through time and space. Scrub through an event while freely repositioning your virtual camera. Any angle, any moment.
Crowd-Sourced Capture
No expensive camera rigs. No special hardware. Everyone at an event already has a camera. We turn their collective footage into an explorable 3D moment.
How It Works
From crowd footage to
explorable moments
Capture
Attendees record an event from their phones. Different angles, different times. No synchronization needed.
Unsynced footageUpload
Contributors upload their videos. Our pipeline aligns, calibrates, and preprocesses the footage automatically.
Auto calibrationReconstruct
Our pipeline builds a volumetric model of the event, fusing all perspectives into a single coherent 3D scene.
Video → Model → 3DExperience
Anyone can relive the moment. Move through time and space, choosing any angle, on any device.

Use Cases
Built for every moment
worth experiencing again
Don't view experiences through cameras. Live in them, then experience them again.
Get inside the game
Synchronized cameras around the court turn broadcast sports into explorable experiences. Get courtside perspective.
Everyone contributes, everyone relives
Guests record from different seats and angles. Collect their footage and create an immersive memory of the day.
Live in the moment, relive it later
Stop viewing experiences through cameras. When the venue captures everything, just be present. Explore it after.
A moment everyone shares
Everyone in the audience has a video. Combine them into a single explorable moment families can relive from any seat.
Complete spatial awareness
Reconstruct scenes from security camera networks. Full 3D understanding of events from any angle.
Every angle of the runway
Fashion shows, product launches, press events. Combine footage into explorable 4D content beyond traditional video.
Vision
People take videos because they want to preserve a moment. A little part of themselves still resides in that media.
We believe the future of memory isn't flat video from a single perspective. It's a living, explorable space that everyone at the moment helped create.
Beyond POV Video
Traditional video locks you into one perspective. BrainDance lets you move around as time progresses — a fundamentally different way to relive an event.
No Hardware Required
Everyone else solved volumetric capture top-down with expensive proprietary hardware. We don't need to own the capture infrastructure — the crowd already has the cameras.
Scales with Uploads
Our cost structure is fundamentally different. We scale with uploads, not camera installations. More people means better reconstruction, not higher costs.
Be Present, Then Relive
At a concert, you don't record because the venue handles that. Now imagine every event works this way. Just live in the moment — experience it again from any angle.
Stop recording.
Start living.
Experience the future of event capture. Upload footage, explore moments in full 4D, and relive them from any angle.
