Paid for B2B networks

Afternoon all


I work for an SME in the North East of England which helps businesses, around the world, to simplify their innovation processes.


Although we have a good client base at the moment we are always looking to expand the numbers

We have gained clients through existing business contacts and haven't really used B2B networks.


I'd be interested to know which paid for business networks, both real world and internet based, other companies have used which have delivered contacts and increased business turnover.


thanks
