Klarity by DemandScience Reviews & Product Details

DemandScience Audience Builder empowers B2B marketers with smarter data to define, refine, and activate target accounts with precision. Built on a verified global first-party data ecosystem of 247M+ contacts and 26M+ companies, it integrates firmographics, technographics, and intent signals so users can move beyond outdated static lists and build dynamic audiences that align with real buyer behavior. With this intelligence at your fingertips, Audience Builder helps you prioritize accounts showing real interest and engage them with the right message at the right time. At its core, Audience Builder is designed to bring clarity to your Total Addressable Market (TAM) and Ideal Customer Profile (ICP). It provides tools to size your market accurately, continuously refine your ICP based on the traits of best-fit accounts, and uncover in-market signals that reveal where prospects are actively researching and evaluating solutions similar to yours. This layered insight ensures campaigns are grounded in verified reality—not assumptions—reducing wasted effort on irrelevant accounts. The platform’s strength lies in its seamless list creation and refinement capabilities. Teams can build and optimize account lists in real time, combining firmographic, technographic, and behavioral intent criteria to construct audiences that reflect evolving buyer behavior. Lists can be exported directly into CRMs or marketing automation platforms, allowing sales and marketing teams to activate insights without friction. All data is backed by DemandScience’s Confirmed Connect™ validation, which guarantees quality and replaces records that don’t meet accuracy standards. Audience Builder is ideal for ABM practitioners, demand gen leaders, sales teams, and any organization seeking to sharpen targeting, improve TAM/TAL accuracy, and prioritize outreach to high-potential accounts. Whether you’re struggling with unreliable data or looking to align segmentation with messaging across initiatives, it delivers a robust foundation for smarter targeting and more impactful engagement. By anchoring audience decisions in verified data and real intent signals, DemandScience Audience Builder helps organizations build confidence in their targeting strategy, reduce wasted campaign spend, and drive measurable momentum throughout the demand generation funnel.

4.5/5

What do you like best about Klarity by DemandScience?

The interface is clear and user friendly. Selecting lists is straight forward and can be done in minutes. The data is good quality and the Support team responsive. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

It would be great if it would allow users to make selection and show cost where a selection will incur additional costs. If that could be sent to the Admin for approval and the user could then be 'switched on' to allow the costs and switched off afterwards - that would be a good feature. It would also be great if could pull mobile numbers, email and tech install in one list. Review collected by and hosted on G2.com.

We have on-demand access to quality data that's easy to navigate and adjust as needed. I also feel that we have support on tap should be have questions. It allows marketing and sales to move quickly when we want to run a campaign. Review collected by and hosted on G2.com.
