What Subspace does
Subspace is a privately held network-as-a-service company founded in 2018 in Playa Vista, California, that operates a parallel internet overlay engineered specifically for real-time applications such as multiplayer gaming, WebRTC voice and video, SIP-based telephony, fintech, and metaverse experiences. The platform is built on a dedicated global fiber network spanning 100+ Points of Presence across 60 countries and ranks among the top 10 most interconnected networks on the internet; it serves more than 400 million end users according to the company's own materials. Its core technology stack includes proprietary AI-driven 'Internet Weather-Mapping' for continuous network condition monitoring, custom anycast routing with shared network state across PoPs, omniscient routers, and in-line DDoS protection that does not add latency.
The product suite consists of four core services: WebRTC-CDN (formerly GlobalTURN), a managed WebRTC delivery and TURN NAT-traversal service; SIPTeleport, a stateful global SIP proxy that accelerates RTP, RTCP, SRTP, and SRTCP traffic for voice and video calls; PacketAccelerator, a no-code global IP-level proxy for TCP and UDP traffic; and two products in controlled introduction, GlobalLoadBalancer and RTPSpeed. All products are exposed through a single REST API and developer console, enabling provisioning in minutes.
Subspace monetizes through a hybrid freemium and usage-based model: WebRTC-CDN, PacketAccelerator, and RTPSpeed offer a $0/month base tier plus usage charges, while SIPTeleport is priced per minute ($0.0015/min voice, $0.015/min video) and RTPSpeed at $0.40/GB. The go-to-market combines a self-serve, API-first product-led growth motion aimed at developers and small customers with an enterprise sales motion for larger deployments, supported by partnerships with major telecom and infrastructure providers including AT&T, Liberty Global, Lumen, NTT, Orange, and STC, and platform integrations with customers such as Avaya and Epic Games.

Product offeringCore offering
Subspace operates a parallel internet overlay network specifically engineered for real-time applications, spanning 100+ global Points of Presence. It sells network-as-a-service products including WebRTC-CDN (managed WebRTC delivery with TURN NAT traversal), SIPTeleport (global SIP proxy for voice/video acceleration), and PacketAccelerator (global IP-level proxy for TCP/UDP acceleration). The platform uses AI-driven weather-mapping to route traffic around congestion, reducing latency by up to 80% and jitter/packet loss by 99%, while providing in-line DDoS protection.
Product overview
Subspace offers a dedicated network-as-a-service platform built specifically for real-time applications. The product suite consists of four interconnected services: WebRTC-CDN (previously GlobalTURN) provides managed WebRTC delivery with TURN NAT traversal; SIPTeleport accelerates SIP-based voice and video traffic; PacketAccelerator offers global IP-level proxy for TCP/UDP acceleration; and GlobalLoadBalancer/RTPSpeed provide intelligent traffic distribution and RTP media optimization. All services share a common REST API for integration and are backed by Subspace's proprietary AI-driven weather-mapping routing system across 100+ global Points of Presence.

Subspace competitors and assessment
Company assessmentBroad incumbents
- Cloudflare: Cloudflare runs a global anycast edge network spanning 300+ cities with CDN, security (DDoS, WAF), and edge compute (Workers). It is the most direct incumbent competing with Subspace's overlay-network, low-latency, and DDoS-protection value proposition, but addresses a far broader workload surface.
- Akamai Technologies: Akamai is the largest traditional CDN and edge platform with global Points of Presence and a security portfolio (including DDoS and bot mitigation). Comparable to Subspace in delivering accelerated content and edge security, though Akamai is optimized for static/streaming rather than real-time interactive workloads.
- Twilio: Twilio is a communications PaaS offering voice, video, SIP trunking, and WebRTC APIs that compete with Subspace's SIPTeleport and WebRTC-CDN at the application/CPaaS layer. While not a network operator, Twilio bundles similar real-time communication outcomes for developers.
- Vonage (part of Ericsson): Vonage provides cloud communications (Voice/Video/SIP) and UCaaS/CPaaS offerings comparable to Subspace's SIPTeleport and PacketAccelerator use cases for enterprise telephony and contact centers.
Direct peers
- Fastly: Fastly provides an edge cloud platform with CDN, edge compute (Compute@Edge), and security services. It directly competes with Subspace's CDN/edge acceleration and programmable networking thesis for developer-first customers building real-time applications.
- Edgio (formerly Limelight Networks): Edgio operates a global edge delivery network with CDN, media optimization, and security offerings targeting streaming and interactive workloads. Comparable to Subspace's video/streaming acceleration and edge security product posture.
- Bandwidth Inc. Bandwidth is a Communications Platform-as-a-Service provider specializing in SIP trunking, voice, and messaging. Comparable to Subspace's SIPTeleport for low-latency global SIP and RTP traffic acceleration.
Emerging players
- Aryaka Networks: Aryaka provides a managed SD-WAN and SASE service backed by its own private global backbone, similar in concept to Subspace's overlay-network model with private fiber and anycast. Both target latency-sensitive enterprise applications.
Regional players
- Console Connect (by PCCW Global): Console Connect operates a global Network-as-a-Service platform with on-demand private connectivity across 100+ data centers. It is comparable to Subspace's overlay-network-then-accelerate model, with stronger telco-anchor roots and footprint across Asia-Pacific.
Others
- Lumen Technologies: Lumen is a tier-1 carrier and Subspace partner providing underlying IP/transport infrastructure. As a broad incumbent, Lumen competes indirectly through its own edge and CDN capabilities while remaining a key upstream network supplier for Subspace.
