We have used Leadfeeder at eeedo for almost a year now and it is definitely worth the money. Their customer success is also top-notch.
I can highly recommend anyone in B2B to try this tool. Even if you just go for the trial period, it will give you insights to sharpen your marketing approach.
I have tried several other tools, this one is the best so far.
I loved how quick and easy it is to set up- great videos to explain how it works and easy to follow.
