Velt

What Velt does

Velt is a B2B collaboration infrastructure company that provides a pre-built SDK enabling product teams to embed real-time and asynchronous collaboration features into their web applications. The platform ships 25+ components spanning contextual comments (canvas, cell, and video variants), notifications, screen recording with AI transcription, multiplayer editing via YJS/CRDT, real-time presence, cursors, and Slack-style huddles, with framework support for React, Vue, Angular, and vanilla JavaScript. Under the hood, Velt integrates deeply with editor libraries (Lexical, SlateJS, Tiptap, BlockNote, CodeMirror) and chart libraries (Highcharts, ChartJS, Nivo, React Flow), and offers enterprise-grade deployment via SOC 2 Type II, HIPAA BAA, self-hosting, and multi-region isolation.

Velt monetizes through a usage-based subscription priced on Monthly-Active-Collaborators (MAC) rather than the MAU-based model used by competitors like Liveblocks and Ably, positioning the product as more cost-effective for B2B applications with many passive users. Distribution is hybrid: developers self-onboard via a free API key and npm packages, while enterprise prospects book demos for self-hosted deployments. The named customer base spans large enterprises (Google, X, Pendo, Varonis, HeyGen, Bigtincan, Leadpages, CloudFactory) and a long tail of growth-stage startups, with stated customer outcomes including 10%+ engagement lift, 26% WAU increase, 5x faster shipping, and $750K in annual savings versus in-house development. Velt has raised $2.77M in seed funding (March 2022) led by Y Combinator with First Row Partners, Spider Capital, and Amino Capital, and is led by CEO Rakesh Goyal and co-founder Solène Oudet.

Revenue model

1. SDK Platform Subscription: Velt offers a Monthly-Active-Collaborators (MAC) pricing model, which charges based on the number of users who actively collaborate rather than all users who access the product. This is positioned as more cost-effective than MAU-based models for B2B applications.

Core offering

Velt provides a collaboration SDK that enables B2B software teams to embed pre-built collaboration features—contextual comments, notifications, screen recordings with AI transcription, real-time multiplayer editing, presence/cursors, and voice/video huddles—into their own web applications. The platform supports React, Vue, Angular, and vanilla JavaScript, and ships with integrations for major editors (Lexical, Tiptap, SlateJS, BlockNote, CodeMirror), CRDT infrastructure (YJS), and enterprise self-hosting with SOC 2 Type II and HIPAA compliance.

Product overview

Velt is a B2B collaboration infrastructure platform offering a complete collaboration stack with 25+ pre-built components. The platform provides both async features (Comments, Notifications, Recording, Activity Logs, View Analytics, Reactions) and realtime features (Multiplayer Editing, Huddle, Presence, Cursors, Follow Mode, Live State Sync). The platform is built around a JavaScript/TypeScript SDK that supports React, Vue, Angular, and vanilla JavaScript, with additional enterprise capabilities including Admin Console, Dev Tools, MCP Server (Beta), and REST APIs/Webhooks for extensibility. The architecture follows a platform-plus-modules design with core collaboration features as the foundation and specialized add-ons like Video Editor, Agent Skills, and Automated AI Reviews on top.

Others

• Appcues: While focused on product onboarding rather than collaboration, Appcues targets the same B2B SaaS product teams with in-app engagement tooling and overlaps in the in-app notification and engagement category.

Broad incumbents

• Firebase Realtime Database / Firestore: Google's Firebase provides realtime data sync and presence that developers can use to build collaboration features; as part of a much larger platform, it competes on the infrastructure layer rather than offering pre-built collaboration UI.
• Supabase Realtime: Supabase's Realtime feature offers presence, broadcast, and database-change subscriptions as part of a broader backend platform, competing with Velt on the underlying realtime layer even if it lacks Velt's turnkey UI components.

Direct peers

• Ably: Ably provides realtime messaging, presence, and pub/sub APIs that developers use to build collaboration features, positioning it as a competing infrastructure layer for Velt's realtime functionality.
• Pusher: Pusher provides realtime messaging APIs used by developers to build presence, chat, and collaboration features, and is a longer-standing competitor in the realtime infrastructure space where Velt operates.
• Liveblocks: Liveblocks offers a real-time collaboration infrastructure SDK with presence, comments, notifications, and multiplayer editing — the closest direct competitor to Velt, frequently cited in Velt's comparison content.

Emerging players

• Knock: Knock provides notification infrastructure for in-app, email, and chat channels, overlapping with Velt's notification and Slack/Teams/Discord sync capabilities as a complementary or competing layer.
• PartyKit: PartyKit offers a developer framework for building realtime, multiplayer applications using durable objects, with significant overlap on multiplayer editing and presence functionality.
• Convex: Convex is a realtime backend-as-a-service platform that provides live queries and sync, increasingly used by developers as an alternative to building custom realtime infrastructure powering collaboration features.
• Hocuspocus / Tiptap Collaboration: Tiptap's Hocuspocus server provides YJS-based multiplayer editing infrastructure for rich text editors, overlapping with Velt's multiplayer editing offering for content platforms.
