@martintalavasek , Your product is <3. Random thought if you have started with B2B sales :
a) Target companies who have recently raised funding. Since they have recently raised money, they have money in their pockets. They will be willing to invest in a tool that helps them in website monitoring.
b) Target companies who are hiring for product manager, SEO manager. It gives the signal that these companies are willing to invest in a product and SEO hence hiring for that role.
