Collar is an AI agent for investment deal teams that automates the deal funnel — sourcing deals against a firm's thesis, ingesting datarooms, running due diligence, sending chaser emails, and drafting financial models, IC reports, and memos while leaving the final investment decision to the user. It serves individual investors, private market firms, and asset managers, running inside the firm's own cloud on SOC 2 Type II and ISO 27001 certified infrastructure.
