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contacts and 26M+ companies, it integrates firmographics, technographics, and intent signals so users can move beyond outdated static lists and build dynamic audiences that align with real buyer behavior.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.

"Better than most mid-level lead products"

4/5

What do you like best about Klarity by DemandScience?

It provides data normally not available through services in the same price range. Lead intent, Systems Used, and Direct dials are normally seen on much pricier programs. With Leadiro, it's no more than the cost of their top tier options. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

There is no ability to quickly identify an already downloaded contact when you run a search under similar criteria. You'll find out when you go to checkout. A small inconvenience, but one, nonetheless. Review collected by and hosted on G2.com.
