About Collar
Summary
Collar builds an AI-native investor relations platform for undercovered public companies. It automates earnings preparation, compiles peer comparisons and question banks, and ranks investors by portfolio fit so CFOs and IR teams spend less time on research and more time in front of aligned institutions. The product replaces weeks of manual work: drafting earnings packets, scouring 13F filings, and building roadshow target lists by hand.
Business model
Demo-request sales process targeting CFOs and IR heads at public companies.
Go-to-market

AI-Native Investor Relations
We are a team of ex-intelligence, ex-finance, and most importantly, 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.
