"Very reasonable cost. Easy to set parameters."
4/5
What do you like best about Klarity by DemandScience?

We found it easy to hone in on the type of companies we wanted to speak with and the cost was very reasonable. The salesperson adapted their pricing model to fit our need which was in between their standard options. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

Nothing yet as we are a new customer. We would like to be very specific when we group leads and some of the data looks to be general in nature. That could mean more manual research. Review collected by and hosted on G2.com.

"The greatest quality of Leadiro is the human support provided by Sumit."
5/5
What do you like best about Klarity by DemandScience?

The ability to export essential information from my day-to-day prospecting has aided our marketing and sales team in securing high-value possibilities for our clients by giving accurate email addresses and direct dials. Building online networks for our marketing and sales staff is one of my tasks in my role. Leadiro helps me to monitor how many of our prospects are in our targeted accounts at the start of new campaigns, allowing me to plan more efficiently for how long it will take to connect with prospects and deliver more actual time metrics to my clients. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

The platform is extremely user-friendly and straightforward. Datasets are updated on a regular basis, and clear data is simply aggregated. I can't say enough about Leadiro's help; Sumit, my account director, is quick to respond and provides immediate solutions. It is really hard to point out anything I dislike.

"A great solution for prospecting, target account planning, and overall business intelligence."
5/5
What do you like best about Klarity by DemandScience?

I like the fact you can go very granular with your searches but leveraging competitors install technology and the buyer intent topics they serve up, this allows me to prioritise the accounts I wish to target each quarter. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

Lack of Chrome extension, this would be useful for when working on LinkedIn and other providers offer this as standard. Review collected by and hosted on G2.com.

"Simple and quick to use with a few flaws and development areas"
4.5/5
What do you like best about Klarity by DemandScience?

Reasonably simple to use, searching and downloading contacts is easy, and fast. Managing contacts, including the suppression lists and bounces, is quick. The platform is self-explanatory for the most part when using it and most likely satisfies someone looking for all the basics in this kind of program. Saving searches is easy. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

Some search features still need development, such as the buyer intent etc. Also, if you're not segmenting your target audience according to the industry and submarket filters that Leadiro offers; you may have to make some adjustments when performing a search.

"Great Provider"
4/5
What do you like best about Klarity by DemandScience?

Other than the joy of dealing with Sumit Popat? The fact that they do try to understand in detail the type of business you are and what you are looking for. They do the extra work to qualify the data which helps massively our team. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

It might be the fact that we are working in a niche area and therefore it is quite hard to find the data. Review collected by and hosted on G2.com.

"Incredibly helpful (and accurate) B2B data"
4.5/5
What do you like best about Klarity by DemandScience?

The UI is easy to use and the data is reliable. You can really dig into granular-level insights for contact information. The intent element of their database is a huge leap for B2B data providers, too. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

It's hard to say at the moment. I work in a very unique industry so, it might be nice to see Leadiro expand their list of contacts in this industry in the future. Review collected by and hosted on G2.com.

"Good value for money"
3.5/5
What do you like best about Klarity by DemandScience?

The tool is fast and responsive, intuitive and easy to use, with various categorizing opportunities to create an outreach campaign or start with ABM. In the sense of value for money, I feel it's a good deal. It includes 11 or so categories for prospect filtration, such as job details (level, function, type), technology in the use and buyer intent. Even though a bit more in-depth data possibilities would be great, I am happy with the simplicity of it all for now. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

It is not possible to filter out contacts using certain technology and having a certain intent. It's one or the other. Overall the data diving should be better in terms of being able to exclude some parameters in more depth. Review collected by and hosted on G2.com.
