DemandScience review and pricing

Enterprise B2B lead generation database with US and EU scope.

By DemandScience (formerly Pure B2B + DiscoverOrg legacy) · Founded 2003 · Danvers, MA · pe backed

DemandScience is the enterprise B2B lead generation database, founded 2003 (originally Pure B2B; rebranded DemandScience 2021 after acquiring DiscoverOrg legacy assets via Mountain Capital). PE-backed by Greenhill Capital Partners. The platform centers on enterprise B2B lead data + intent signals + lead nurture for high-volume B2B demand generation. Strengths: enterprise B2B lead database depth, mature US + EU contact coverage, intent data integration, broad enterprise customer base, and consultative implementation services. Best fit for enterprise B2B demand generation teams wanting high-volume lead data with intent. Trade-offs: pricing meaningful + opaque (enterprise-only sales process), brand recognition declined post-rebrand, lead data quality variable per recent buyer reports, customer support quality variable, and PE-backed cycle pattern.
