Managed B2B demand gen. Check the 2024 breach first.

DemandScience runs managed B2B demand generation: content syndication, lead delivery on a cost-per-lead basis, intent data, display and account targeting, with an intelligence layer and managed services wrapped around it. It has repositioned hard against platform tools with a more pipeline, less platform message, and added visitor identification, web personalisation from an acquisition, a content intelligence product and an AI visibility capability. Delivery is service-led rather than software you operate. The important thing a UK buyer should know is a documented security incident: a dataset attributed to DemandScience appears in the Have I Been Pwned breach index, dated February 2024 and added that November, covering well over a hundred million accounts including names, employers, job titles, phone numbers, addresses and social profiles. The company initially denied a compromise, then said the data came from a system decommissioned around two years earlier.

Our verdict

Judge this as a lead generation service rather than a tool, because that is what it is: you are buying delivered leads, not software you operate. On that basis it is established, has been doing it for over a decade, and has broadened sensibly into intent, visitor identification and AI visibility. The repositioning away from platform sprawl is a fair read of what buyers actually want. We would not list it without the breach, though. A dataset attributed to the company sits in the public breach index covering over a hundred million records with substantial personal detail, and the initial response was a denial before an explanation about a decommissioned system. Record counts vary between reports. No regulatory action followed that we could find, which is not the same as a clean bill. Since the entire business is third-party B2B contact data for outbound, the lawful basis and PECR diligence sit with you as the buyer, and that history makes the diligence more important rather than less.

Best for: B2B marketers buying leads on a cost-per-lead basis who have done their own data protection diligence first.
