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contacts and 26M+ companies, it integrates firmographics, technographics, and intent signals so users can move beyond outdated static lists and build dynamic audiences that align with real buyer behavior.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

What do you like best about Klarity by DemandScience?

The team at DemandScience Intelligence is fantastic, they’re very attentive. People like Greg Jordan and Rosie have really made an effort to make sure we’re taken care of. Customer service is definitely lost nowadays, but not here! Willing to hop on calls at anytime and make sure the correct help is administered, made our onboarding process even easier than it is to start.

"Great sales prospecting tool"

5/5

What do you like best about Klarity by DemandScience?

The former Leadiro (DemandScience Intelligence) has helped us significantly in gathering the lead details and contact information for them. It enabled us to do our job smarter and more efficiently when marketing our products to other organizations. The information is up-to-date and accurate! Also, a fraction of the cost of the other data/intent companies we’ve looked into. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

It provides so much data sometimes, which is helpful for our marketing team, but our sales team really only cares about the basic contact information. Review collected by and hosted on G2.com.

Recommendations to others considering Klarity by DemandScience:

If you're looking for a data/contact info and intelligence, this is your tool. The big market leaders would blow our budget while DemandScience Intelligence offers more than enough to allow you to remain competitive. Review collected by and hosted on G2.com.

What problems is Klarity by DemandScience solving and how is that benefiting you?

It is our go-to-resource for contact information for our lead gen activities. Main points of information are email and phone number (the addition of Confirmed Connect proves the accuracy of the data) as well as intent, narrowing in on our audience. Everything we need is right in front of us! Review collected by and hosted on G2.com.

The accurate intel on prospects is what we’ve struggled with in the past and was the biggest selling point here. That is no longer an issue for us.

What do you like best about Klarity by DemandScience?

I have been using DemandScience Intelligence/Leadiro with 2 different organizations.

Their sales and customer service teams have been very helpful to me and my team. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

I have no complaints as any issues I've run into, their team jumps on to resolve for me and my team. Their customer service team is very responsive. Maybe just update the interface a little. Review collected by and hosted on G2.com.
