Signal Labs Has Acquired BrassRing
The future of work runs on signals, not job openings.
BrassRing runs hiring and onboarding for some of the largest, most regulated enterprises in the world, and has for twenty-five years. That run produced something almost no other applicant tracking system has: a record of who got hired, who stayed, and who performed across Fortune 500 companies. Signal Labs is pairing that record with SignalOS™, its operating system for enterprise attention, to give leaders a working coordination layer for workforce decisions: which roles are at risk of stalling, which candidates are worth a second look, and which moments deserve attention before the window to act closes. The future of work isn't more tools. It's infrastructure that decides where attention goes, and workforce decisions are the highest-signal fraction of that attention inside any enterprise. This acquisition gives Signal Labs a twenty-five-year head start on building that.
Founder & CEO Rajeev Ronanki on BrassRing Acquisition
Hiring is the earliest, highest-signal read any company gives about where it's headed, which is why BrassRing is core to how Signal Labs sees the Future of Work.

Signal Labs Acquires BrassRing, Bringing Systems of Attention to the Future of Work
The acquisition coordinates Signal Labs' SignalOS™ operating system with 25 years of talent outcome data from BrassRing, so enterprises see signals on which roles, candidates, and moments deserve attention before the window to act closes.
Why BrassRing
“BrassRing has 25 years of hiring outcomes across 172 countries and 42 languages, and Signal Labs turns that memory into attention. We can tell a leader which five roles are most likely to fail this quarter, and which people already inside the building look like their next generation of leaders. That is the Future of Work we are helping enterprises build toward. People still make the decisions. What reaches them better informs and arrives in time to matter.”
Rajeev Ronanki, Founder and CEO, Signal Labs
That data, tied to real hires and real performance, is what most competitors don't have. Pairing it with Signal Labs' Systems of Attention technology unlocks capabilities that haven't existed in talent acquisition:
- Predictive views of which roles will stall before a recruiter feels it
- A real-time read on which candidates in a pipeline will accept, stay, and perform
- A coordination layer that turns years of hiring data into decisions a CHRO can act on this week
