The Forrester Wave™: Marketing And Sales Data Providers For B2B, Q1 2026
Vendors or products added in this year’s report may indicate a change in the market, change in evaluation criteria, or change of focus by the vendor.
Vendors or products dropped from one year to the next may indicate a change in the market, change in evaluation criteria, or change of focus by the vendor.
The Forrester Wave evaluation is an assessment of the top vendors in the market; it doesn't represent the entire vendor landscape. Additional information about this market and additional vendors that Forrester considers to be notable for enterprise clients can be found in the corresponding report: The Marketing And Sales Data Providers For B2B Landscape, Q4 2025.
A: Vendors may appear in one evaluation and not the next due to strategic shifts such as no longer prioritizing the enterprise market, changing business direction after acquisitions, or refocusing on different market segments (e.g., SMB vs. enterprise). Vendors must meet specific inclusion criteria including meaningful market share as a primary account and contact data provider to enterprises, at least $10 million USD in annual revenue from B2B marketing and sales data, and mindshare among Forrester's enterprise clients.
