Liveblocks is a technology company.
Liveblocks provides APIs and SDKs for developers to integrate real-time collaboration features into their applications. Its tools abstract the complexity of building multiplayer experiences, offering capabilities like presence, shared cursors, and state synchronization. This allows product teams to efficiently transform single-user applications into dynamic, engaging, and AI-ready collaborative platforms.
Steven Fabre co-founded Liveblocks, launching the company in 2021. His insight arose from the significant challenges of building real-time collaborative functionalities from scratch. Liveblocks was established to simplify this, empowering teams to quickly embed sophisticated multiplayer features and advance collective digital work.
Liveblocks primarily serves developers and product teams enhancing their applications with embedded collaborative capabilities. The company’s mission is to foster a more connected and interactive digital landscape, enabling individuals and artificial intelligence to operate effectively together within any application. They envision a future defined by intuitive, fluid shared digital workspaces.

Liveblocks is a technology company that provides a collaboration layer for software products, offering ready-made APIs, SDKs, and features like real-time multiplayer editing, comments, notifications, and AI agents to enable human-AI collaboration within apps.[2][5] It serves developers and engineering teams building web and mobile applications, solving the complex challenge of implementing scalable real-time collaboration without building backend infrastructure from scratch—such as handling WebSockets, conflict resolution, and state management.[1][4] The platform has demonstrated strong growth momentum, scaling to nearly half a billion WebSocket messages per day, powering active users and rooms for thousands, and raising $6.4 million in funding since its 2021 launch.[4][5][7]
Liveblocks was founded in 2021 by Steven Fabre (CEO) and Guillaume Salles, who began collaborating a few years earlier on a browser-based presentation and video tool requiring real-time features like live cursors and shared editing.[1][7] Frustrated by the time spent on collaboration infrastructure—rather than core product mechanics—and dissatisfied with existing solutions, they built their own APIs and pivoted entirely to productizing them as a service for other developers.[1][7] Early traction came from a private beta of core APIs like live presence and storage, leading to a $1.4 million pre-seed round from investors including Boldstart, Seedcamp, and angels like Ian Storm Taylor.[1] The fully remote team, now 11-50 employees based in San Francisco, has evolved from foundational multiplayer tools to a comprehensive platform.[6][7]
Liveblocks rides the wave of real-time collaboration demand in modern apps—fueled by user expectations for Google Docs-like experiences in tools for design, livestreams, and productivity—while extending to AI-native products where humans and AI co-edit in shared spaces.[4][5][8] Timing aligns perfectly with post-2021 remote work surges and AI proliferation, as developers avoid reinventing WebSocket scaling amid talent shortages; Cloudflare's Durable Objects enabled their pivot to global reliability without 40% engineering expansion.[4] Market forces like rising app engagement needs and AI integration (e.g., copilots) favor them, influencing the ecosystem by democratizing multiplayer/AI features—letting startups ship faster and incumbents add collaboration without infrastructure lock-in.[3][8]
Liveblocks is poised to dominate as the go-to collaboration engine for AI-era products, with chapter 3 emphasizing human-AI interfaces via AI Agents and beyond.[8] Expect expansions in AI tooling (e.g., advanced memory/context handling), deeper integrations for no-code/low-code platforms, and usage-based monetization as collaborative apps proliferate. Trends like edge computing and multimodal AI will amplify their edge, evolving their influence from dev tools to essential infrastructure—much like how they transformed a presentation prototype into a scalable layer powering millions of interactions.[7][8] This positions Liveblocks to fuel the next wave of engaging, revenue-generating products.
Liveblocks has raised $6.0M in total across 2 funding rounds.
