"Great database of B2B contacts"
4.5/5
What do you like best about Klarity by DemandScience?

Leadiro has a very intuitive interface, a great overall database of contacts and excellent filters for search results. You can get to the contacts you need to continue your sales process quickly and without any hassles. I would recommend Leadiro to any sales manager or business development representative looking for a new source to prospect leads. Leadiro is both a very effective and a very affordable tool that will be an asset to your sales efforts. The integrations with Reply.io and HubSpot were also great selling points. This helped us further automate our internal lead generation process and save valuable time and energy best spent acquiring new business. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

It would be nice to see more global B2B contacts added in the future. There seems to be more of a focus on NA and EU with the current database. Review collected by and hosted on G2.com.

"Great platform, quality and quantity of data need to be improved"
4/5
What do you like best about Klarity by DemandScience?

I loved the ease of use of this product as well as its many features such as list upload. The navigation on the site is great, and the filtering options were exactly what I needed to get to a level of specification that made sense for the leads I was looking for. Very good value for money. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

I had about 10 % bounceback and some contacts had no emails at all. Would have been much easier to have a drop-down list for regions of the UK. Also better if you could filter industries more specifically e.g. what sector of wholesale or retail i.e. gardening, toys Review collected by and hosted on G2.com.

Nothing - maybe some extra features and sometimes I get randomly logged out but might be my computer to be fair : ) Review collected by and hosted on G2.com.

"Great new option in the market"
5/5
What do you like best about Klarity by DemandScience?

Is a simple but powerful tool, thank the filter options it offers. This tool is walking in the right direction, I probably said they will be acquired by other by company in the industry. Leadiro offers a limited information but valuable resulting on profit for the business. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

There's nothing I dislike, but if I need to say, I would love to have a mobile version as an application, since the mobile world is becoming a daily necessity, it's needed to have an easy and portable way to access this app. Review collected by and hosted on G2.com.

"The support that you receive is amazing quick response and great help"
5/5
What do you like best about Klarity by DemandScience?

they stand behind their product and if something goes wrong they support you very well you should make companies that are looking at reordering using the same account easier by just going on your website Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

that to reorder another quarter was not as smooth and since the emails have been paid for companies should have access to them and not be locked out of system. this may entice them to get more services Review collected by and hosted on G2.com.

"Leadiro leads to account engagement success"
4.5/5
What do you like best about Klarity by DemandScience?

The simplicity of use, the volume of contacts and most importantly - the engagement of those contacts with our clients' brands Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

As with all B2B contacts databases - there are a lot of Titles/Functions that don't fit neatly into traditional forms and so they go hidden and unused - this could be such a wonderful add Review collected by and hosted on G2.com.
