ZoomInfo SalesOS

Broadest US B2B contact database despite trust battering.

By ZoomInfo Technologies, Inc. · Founded 2007 · Vancouver, WA · public

ZoomInfo SalesOS is the broadest US B2B sales intelligence platform, founded 2007 and public since 2020. The product covers contact data + intent (Bombora-licensed) + account research + engagement (separate Engage product, see [Top 10 Sales Engagement](/top-10-sales-engagement-software)). Strengths: largest US B2B contact database, mature firmographics + technographics, public company financial transparency, and strong fit for enterprise outbound at scale. Trade-offs: pricing has escalated significantly through 2024-2025, customer trust battered by aggressive renewal practices and "auto-renewal" disputes that became a public reputation issue, and EU contact data quality is materially weaker than Cognism. The vendor's 2024-2025 customer-NPS decline is real and well-documented.
