"Leadiro is good for organizations with a broad reach, but maybe not for those with specific targets."
2.5/5
What do you like best about Klarity by DemandScience?

The data was pretty accurate - we had a really low bounce rate with leads that we pulled. We were able to generate some new business with the tool as well which was helpful.

The pricing is also very good - we were quoted rates over 10x what Leadiro was charging for some similar tools. Perhaps they had better data quality but if you have a lower budget, Leadiro is a good solution to test out having a lead gen tool. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

Seemed to be missing a lot of data for companies we'd expect a tool to have. Large tech companies we were trying to sell into would have 0 contacts which was surprising, while some smaller companies would seemingly have their entire staff in the tool.

You also cannot look for specific persons - you have to look by company, title, industry, etc. Review collected by and hosted on G2.com.

"My experience has been good, I do like what Leadiro offers for the cost. "
4.5/5
What do you like best about Klarity by DemandScience?

I really like the verified email address, that is what I like best of the offering. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

I wish there were more phone number contacts in the platform, that would help me with my need, also I would like to be able to do a search for multiple items. Say the city for example. I would like to search for city 1 and city 2 simultaneously, which doesn't look like that is available. I even pinged through chat to ask. Review collected by and hosted on G2.com.

"Leadiro review"
5/5
What do you like best about Klarity by DemandScience?

What I like best is the ease of use. the support given by Leadiro. Flexibility in use and affordability. using Leadiro is very simple and allows for me to focus on other aspects of the business once I have the leads. I like the option to start and stop as required. since se are a small company this flexibility allows us to work the leads without having to pay every month. Customer service is excellent. they re very patient. Best of all it was a soft sell. I did not fee pressured in any way compared to other companies I was comparing prior to getting Leadiro. Great experience working with Leadiro Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

What I dislike is the fact that lack of information of revenue/Assets of the companies I am searching. I would like this to be included and be able to sort based on company revenue. this would help for specific enterprise searches. I would also like to be able to search by key word in Job Title.

"Leadiro - Brilliant source of Quality Data for Business!"
4.5/5
What do you like best about Klarity by DemandScience?

The best thing experience we have had with Leadiro so far is just how user-friendly the User Face is and how helpful the Team is when asking questions via the online chat. We love the conversion rate that we have with using Leadiro Data and because we target various geographies around the globe, the fact that there is data available for all these countries is an added bonus! Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

Something I came across this week is that there is not an option to exclude options from the Technology Install - this was a requirement on one of our more complicated campaigns and could possibly be a useful feature to add. We would also like to see some more Direct Dials. Review collected by and hosted on G2.com.

"Great start, but more to come"
3.5/5
What do you like best about Klarity by DemandScience?

The convenience and ease of use. Very straight forward to select contacts via a range of criteria and just as easy to export. Quality of data seems to be pretty high as well, minimal bouncebacks and a promise of returning credits if they do bounceback. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

Bit of a "clunky" UI and UX. it seems illogical to me that once you've selected and exported a contact, there's no annotation next to them in future searches. This means that if you've created a large list recently, then log in to create another similar list within a few weeks after, you can end up reselecting these contacts and you don't find out until you head to the checkout, which can often mean a lot of work down the drain. Also, not particularly keen on not being able to "save" selected contacts to continue later on at a different workstation, not can you share a list with a colleague prior to downloading to verify the contacts are of suitable standard.
