When you start a company in Finland you can be sure of two things: you will start receiving a lot of bills from places you never knew existed, and you will get spam.
Businesses are required to submit information to the National Board of Patents and Registrations (that’s a long name) which, in turn, makes that information public on www.ytj.fi. They list, among other things, your email and your company’s web address. They try to prevent spam by only using images when displaying email addresses.
Still, you can access all that information in a very easy manner (so easy that you can send spam to newly-registered companies) via providers like www.finder.fi. It will cost you, but you will have a complete database of companies registered in Finland and their contact information. Can you guess where this is going?
