Paid against free › Sales & Customers › Lead Generation & Prospecting › Intent Data · Talking to customers on Repo Radar
Intent data tools show which companies, and sometimes which people, are researching a purchase so sales and marketing can reach them first. The paid field splits into contact databases that add intent topics to prospecting (Apollo.io, ZoomInfo, Seamless.AI, Amplemarket), account-based platforms that predict buying stages (6sense, Demandbase), website visitor identification tools that turn your own traffic into leads (Lead Forensics, Leadfeeder, RB2B) and Bombora, whose co-op topic data many of these platforms use. Open-source projects cover parts of the job: Beton Inspector scores accounts from product usage, OpenGTM and YALC build signal workflows on provider data, SignalScout, LeadEcho and subscope find buying conversations on social sites, and small visitor identification projects resolve companies by reverse IP.
