"The best cost-effective for Technographic Data"
5/5
What do you like best about Klarity by DemandScience?

I looked for a solution able to do Technographic Data well. All competitors can do it but they are much more expansive than Leadiro. I'm really glad about the platform and its features. The platform should help many companies working in an ABM approach as it can provide really good data such as technographic, market size and industry areas. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

In the Technology Install section, Leadiro allows extracting only the employee´s info making it not able to extract just the companies info. As it charges for each technology install you extract, it would be unable to extract technology install for every employee's info just to get the companies that are using the solution you are targeting. Luckily the customer success team was able to help me and provided me the companies technology list. Review collected by and hosted on G2.com.

"I had a great experience with Leadiro!"
4.5/5
What do you like best about Klarity by DemandScience?

I liked the simplicity of the Leadiro software. Also, it's a fair price for what you're getting. It is easy to filter out the contacts you want to email market or sell to. It takes seconds to get in and get out with what you need. It had all the fields for each contact that we needed to accomplish what we were trying to do. Overall, the software does exactly what you want it to do in my opinion. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

The bounce rate for emails addresses seems to be higher than the benchmark for the industry. That is to be expected with the price they charge though. Something else I didn't love was that I accumulated contact credits faster than I could use them so I didn't love that I had to continually pay each month for a higher number of contacts was higher than I needed.

"Leadiro is the perfect data provider for all of your outbound marketing"
4.5/5
What do you like best about Klarity by DemandScience?

Leadiro is a great tool, the data quality, the filtering ability to segment data to the finest details, but my favorite part of Leadiro is the price point, we are using the professional plan which only costs $99 a month, which is a steal in comparison to other data providers, also there are no long term contracts. Its month to month and cancel anytime (not going to be cancelling but its nice to know that their won't be any hassle in getting cancelled). Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

The only thing I don't like about Leadiro is related to pricing ironically enough, all payment options are processed in US dollars, we are based in the UK so I'd like to pay in British Pound Sterling. Its a personal preference, but thats really the only qualms we have with the service. Review collected by and hosted on G2.com.

"Leadiro is the Best Data Provider to use in Telemarketing and Email Marketing Campaigns!"
4.5/5
What do you like best about Klarity by DemandScience?

Leadiro is a great data provider, it is easy to use and allows quick and concise segmentation to target the contacts that you would like to specifically target. You select contacts based off of filters like job title, location, etc. and download, it's as simple as that. The default export option is via excel files which makes it handy to import the data into your own in-house CRM and Leadiro has integrations with providers like Reply.io, Salesforce and HubSpot which is a great option if we decide in the future to move to one of those providers. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

One of the only gripes I have with Leadiro is the suppression feature, as it is applied during the check-out process rather than in the preview screen. That being said I find with other providers the system at least on my end always feels sluggish when a suppression file is loaded, Leadiro does not suffer from this thankfully. It's a bit of an annoyance, but it works which is the main thing I suppose :D Review collected by and hosted on G2.com.

"Using Leadiro for Marketing Campaigns"
4.5/5
What do you like best about Klarity by DemandScience?

Leadiro is a great platform! It allows you to segment by city, state, country, job title, function, industry, employee size, direct dials, basically every category we want to segment by! They have a large pool of contacts available 35m+ across 90 countries. We have been using the platform in our marketing campaigns we have had great success through the data we have received from Leadiro. The team have been great at answering our questions too, they are quick, concise and answer all the questions we have! Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

We would like to segment by zip/postal codes at times, unfortunately you are not able to in the platform. You can ask the team to run the searches in the backend they add the search results into your ABM filter. It's a nice option but its a bit slow in comparison to how quick it is to segment by city, state, and country in the platform. Review collected by and hosted on G2.com.

3.5/5
What do you like best about Klarity by DemandScience?

There were a good number of international leads, which most other companies do not have. Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

You cannot choose when the leads were last verified. Some of the leads provided were old and no longer in use, or the employee had moved to a different company. Review collected by and hosted on G2.com.

"Review of Leadiro"
4.5/5
What do you like best about Klarity by DemandScience?

Leadiro is a very easy to use platform, its very intuitive and if you ever have any questions the team is always there to help out with any of our queries! The database has a great coverage of over 90 countries worldwide which is great for our marketing campaigns, we can get data for any campaign and the data quality is top notch! Review collected by and hosted on G2.com.

What do you dislike about Klarity by DemandScience?

I haven't found many issues with Leadiro, they have helpful "help" articles, but sometimes a video would be a quicker solution, that being said its just as easy to drop the support team a message in the bottom right corner they're very helpful and get you back on track with targeting potential leads :) Review collected by and hosted on G2.com.
