What is
Zefram
Zefram is a B2B sales platform built on national company registry data, enriched with financials, websites and live signals such as hiring and growth. Sales teams filter the market into a target group, then the Zefram Agent researches each company, finds the matching decision-maker, writes a tailored message, sends it from your mailbox and follows up. Every touch is logged to the CRM, and the agent flags when a rep should step in, for example with a call.
