## Summary

Developer SDK for embedding 25+ real-time collaboration features in SaaS apps in 30 minutes; $2.77M YC-backed at $2M revenue with 6x growth serving Pendo and Leadpages.

## Company Overview

Velt is a developer collaboration toolkit that provides a JavaScript/TypeScript SDK enabling product teams to embed 25+ real-time collaborative features into their SaaS applications — including AI-powered comments and annotations, live multiplayer cursors, @mentions, in-app notifications, and guided walkthroughs — without building custom collaboration infrastructure. Backed by Y Combinator, Velt raised $2.77 million in seed funding, achieved $2 million in revenue in 2024 with 6x year-over-year growth, serving customers including Pendo and Leadpages who report up to 23% increases in weekly active users after implementing Velt's collaboration features.

Velt's SDK philosophy is that collaboration features are table stakes for modern SaaS products but expensive to build correctly — real-time multiplayer state sync, presence indicators, comment threading, and notification systems require significant backend infrastructure and ongoing maintenance. Velt's embeddable components provide production-quality implementations in under 30 minutes of integration time, giving product teams the ability to add these features to their roadmap without dedicating engineering sprints. The AI layer adds context-aware commenting where AI can summarize discussion threads or suggest resolutions.

In 2025, Velt competes in the developer collaboration infrastructure market with Liveblocks (real-time collaboration APIs), Ably (real-time messaging infrastructure), and in-house development for embedding collaboration features in SaaS products. The "collaboration as infrastructure" category has emerged as SaaS products increasingly need multi-user real-time features that were previously only found in design tools like Figma and documents tools like Google Docs. Velt's 6x revenue growth demonstrates strong market demand. The user engagement improvement data (23% WAU increase at Pendo and Leadpages) provides compelling ROI metrics for sales. The 2025 strategy focuses on growing the developer community through documentation and developer experience, adding more collaboration component types, and deepening the AI-powered features that differentiate beyond basic multiplayer.
