How we Compare with
Lead Databases

Global B2B Lead Lists and Databases

We specialize in Global Data Acquisition, in multiple languages, spanning across sectors. What sets us apart is our end-to-end research services, our high accuracy rate, and our experience, and flexibility to accommodate changing client needs.

Before you choose a B2B Lead List Company, check for these factors

How Ascentrik Research differs from Lead list companies

Custom Data with 100% Accuracy

Sales leads companies suffer from Stale Data

Since we do not function as a sales leads company, we provide complete customised marketing data to every client.

N Sales leads companies scrape data from online sources while Ascentrik provides custom data for niche targets.

N Lead list companies build a standard database and sell to multiple buyers, while Ascentrik studies your company, market, competitiors etc.

N With Sales leads companies you and your competition gets the same data while Ascentrik’s data becomes your own intellectual property giving you higher ROI.

N Lead list companies refresh data weekly, monthly or quarterly, leading to at least 5% bounce rate. But since Ascentrik does not store databases, our data is always freshly sourced and never stale. We tell you the date and time of the last update.

N Most Sales leads companies provide a software solution that gives you a list of contact details, but Ascentrik gives you a team that provides an end-to-end solution, until the completion of your campaign.

N Ascentrik Research supports you all through your marketing campaign by providing replacements, if a lead changes his job. We provide all the data support you need, even inside sales activities.
