Spatius

What Spatius does

Spatius, operated by SPATIALWALK PTE. LTD. and headquartered in Singapore, provides real-time AI avatar infrastructure for embedding conversational digital humans into third-party applications. Its core product is a cloud-edge hybrid platform in which the cloud streams only lightweight motion data (10-20 KB/s) while the avatar is rendered locally on the user's device via a 3D Gaussian Splatting (3DGS) pipeline, supporting 1080p at 25fps on entry-level chipsets without dedicated GPUs. The platform exposes native SDKs for Web, iOS, and Android, accepts Bring-Your-Own LLM/TTS stacks through LiveKit, WebSocket, or Agora transports, and includes a proprietary lip-sync engine covering 100+ languages with sub-300ms added latency. Differentiated product lines include an AvatarKit SDK, AvatarKit RTC for LiveKit, a Custom Avatar Generation feature (beta) that produces branded 3DGS avatars from a single photo in approximately three hours, and a free Live AI Avatar Cost Calculator tool.

The company monetizes via a tiered subscription model ranging from a free evaluation tier to a $299/month Scale plan, with usage-based overages at $0.007-$0.009/min and a custom Enterprise tier that adds SOC II, GDPR, SLAs, and isolated deployment. Go-to-market is dual-track: product-led growth targeting developers through a free playground, self-serve Studio, public GitHub repo, and Discord community, alongside enterprise sales via engineer-led 30-minute demos for buyers in language learning, HR tech, healthcare, retail, and AI hardware. The platform cites 12 regions of operation, 99% device coverage, and a flagship customer engagement (Midoo AI) running 15,000+ daily avatar sessions with 173% month-over-month usage growth. Spatius is privately held, with no disclosed funding rounds, headcount, or institutional investors identified in the source materials.

Spatius's competitive positioning is anchored on a claimed 21x cost advantage over the industry average ($0.007/min versus ~$0.15/min) and a 98% bandwidth reduction versus cloud-streamed competitors, achievements it attributes to on-device rendering rather than aggressive pricing. The strategic focus is on interoperability — BYO LLM, multi-protocol transport, plug-in compatibility with LiveKit — and on mobile-first deployment in bandwidth-constrained markets, with a stated long-term target of embedding avatars into AI hardware, kiosks, and in-vehicle interfaces.

Core offering

Spatius provides real-time AI avatar infrastructure combining cloud-side motion inference with on-device rendering SDKs (AvatarKit) for Web, iOS, and Android. The platform accepts audio from any ASR/LLM/TTS stack via WebSocket, LiveKit RTC, or Agora and outputs lip-synced 3D avatar video rendered locally on user devices. The platform supports a Bring Your Own LLM model and offers tiered subscription plans with usage-based billing, custom avatar generation from a single photo, and a free stock avatar library.

Product overview

Spatius is a real-time AI avatar infrastructure platform built around on-device edge rendering. The core offering consists of the Spatius Platform (cloud-side inference and motion data delivery) combined with the AvatarKit SDK for Web, iOS, and Android (client-side rendering). The platform renders avatars locally on user devices at 10-20 KB/s bandwidth, dramatically reducing cloud GPU costs. Integration paths include direct SDK use, the LiveKit Plugin (livekit-plugins-spatius) for LiveKit Agents, and Bring Your Own LLM via WebSocket/RTC. Additional offerings include Custom Avatar Generation (3DGS from photos, in beta) and a free Stock Avatar library. The Live AI Avatar Cost Calculator is a free developer tool for competitive analysis.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Synthesia: Synthesia is a leading enterprise AI video avatar platform for corporate training, marketing, and communications. Comparable avatar technology and customer base but skewed to scripted/asynchronous video rather than real-time conversational avatars.
• D-ID: D-ID provides AI avatar video generation and conversational avatar APIs across enterprise and creative segments. Comparable avatar technology stack but broader portfolio than Spatius's real-time conversational focus.
• HeyGen: HeyGen is a broader AI avatar video platform spanning marketing, localization, and enterprise video production. Comparable on avatar generation technology and customer overlap, but serves a wider (less real-time-conversational) use-case set than Spatius.

Others

• Runway: Runway is a generative video/AI platform explicitly included in Spatius's cost calculator. While Runway's core focus is creative video generation rather than real-time conversational avatars, it represents an adjacent frontier-model entrant that could expand into Spatius's space.

Direct peers

• Tavus: Tavus provides a developer API and platform for real-time conversational AI avatars with personalized video generation. It is the most directly comparable competitor on positioning, SDK model, and per-minute pricing that Spatius explicitly benchmarks against.
• Anam: Anam offers real-time AI avatar streaming for conversational applications and is explicitly listed in Spatius's cost calculator. Comparable on real-time avatar focus, BYO-LLM model, and developer/SDK-led GTM.
• Beyond Presence: Beyond Presence builds real-time avatar infrastructure for conversational AI products and is benchmarked in Spatius's cost calculator. Comparable on real-time avatar delivery, SDK/developer model, and target verticals like customer service and AI companions.
• Simli: Simli provides real-time AI avatar streaming via API for conversational applications and is benchmarked in Spatius's cost calculator. Directly comparable on real-time avatar-as-a-service positioning and developer integrations.
• LiveAvatar: LiveAvatar is a real-time AI avatar platform that competes head-to-head in Spatius's pricing comparison. Comparable on SDK-first real-time avatar delivery and per-minute usage pricing model.

Emerging players

• Soul Machines: Soul Machines builds autonomous digital humans for enterprise customer experience and is frequently benchmarked in the conversational avatar space. Comparable on real-time digital human rendering and enterprise CX use cases, though focused on higher-fidelity studio avatars.
