Know your market as well
as your position in it

For example: 70% of your clients are manufacturing companies from Prague and the Central Bohemian region with 10–50 million in revenue. They have been in operation for over 5 years and have more than 5 employees. If you have 200 of such clients out of the 2,000 in the Czech Republic, you know your market share is 10%.

We will find you more
clients immediately

We’ll give you the remaining 90% of the market – those 1,800 companies that meet the criteria for your typical client.

  • 100% verified phone number, email address and website
  • development of revenue, number of employees and business area
  • rating, finance analysis, public contracts and funding

Don’t forget about
your existing clients

We will show you which of your clients are doing well and which not so well. The ones that have growing sales are the ones you want to target.
