Librar Labs

Librar Labs is building what every AI company desperately needs but nobody wants to talk about: working data. Their product OSSUS is a self-healing data infrastructure that deploys autonomous AI agents to continuously audit, merge, enrich, and correct fragmented, unstructured records in real-time. The cold truth is that most companies building AI have amazing models and garbage data—and that's where Librar comes in. They're essentially being the data plumber that makes AI actually usable.

OSSUS crafts what they call the intelligence layer of literature, turning messy collections into trusted, agent-ready systems of truth. The pitch is simple: AI is ready, the data isn't. They're backed by founders and operators who believe organizing the world's data is the prerequisite for the superintelligence of tomorrow. This is infrastructure work—unglamorous, technical, and absolutely essential. The boring layer beneath the flash.

They're YC-backed and hiring. If you're drowning in data chaos and need someone to actually fix it, Librar Labs might be your answer.
