What is Lead Onion?
Lead Onion is a buyer intent data platform designed to identify companies and individuals who are actively researching relevant products or services. It aggregates more than 50 billion signals drawn from 24 sources into a single accessible interface, allowing sales and marketing teams to prioritize the top 10% of prospects showing the strongest purchase readiness. Actionable insights are surfaced within three minutes of setup, so teams can act on fresh data rather than waiting for lengthy data preparation.
The platform excels at targeting in-market accounts, personalizing outreach based on behavioral signals, and accelerating pipeline growth. Rather than relying on broad demographic targeting, teams can see exactly who is engaged and at what stage of their buying journey, which translates into more relevant conversations and higher conversion rates. Lead Onion connects with existing CRM and sales tools, improving the quality of lead data flowing into those systems.
Within a go-to-market stack, Lead Onion serves as a dedicated intent data layer that powers sales intelligence and campaign optimization. It is not a full CRM or a marketing automation system, so contact management and communication workflows still require other platforms. Its purpose is focused: provide precise, high-confidence intent signals that enable smarter account targeting and faster pipeline development.
