London-based entrepreneur John Horsley will unveil his new company Marzar at this month’s Web2NewYork networking party. Marzar is an ‘enterprise 3.0 business networking and collaboration tool’ according to Horsley.

‘While personal networking sites such as MySpace and Facebook have seen phenomenal growth in the last two years,’ Horsley says, ‘there has not, to date, been an adequate digital networking tool for the global business community. Marzar has been created to fill that void.’

Horsley claims the site has already signed up a thousand CEOs and senior executives. Marzar will provide ‘a collaborative working environment to facilitate global project management’ as well as contact management.
