## YC company profile

AI-Native Investor Relations

We are a team of ex-intelligence, ex-finance, and ex-founders who have known each other for over 5 years.

Collar is redefining investor relations. 

Right now, investor relations is an under-appreciated yet sweeping function. 
They have a bird’s eye view of what external stakeholders want, and also work with internal business units to create a grand vision of a company’s future.

But they’re doing it with their hands tied behind their back.

Finance AI tools today are built for investors not investor relations, leaving teams using ad-hoc unreliable workarounds, and CFOs are stuck always reporting rather than acting on insights to optimize operational workstreams.

Before earning calls, Collar prepares CFOs through proactive earnings calls prep, investor targeting and fully citation-backed live teleprompters, saving them hours of work.

After earning calls, CFOs use Collar’s trusted agentic AI systems to optimize identified underperforming workstreams with little manual modification needed. 

Redefining investor relations from a tedious cost centre headache, into a whole-of-company profit maximising function.
