The site gives entreprenuers the chance to communicate with experts, discuss key issues or concerns and receive advice from external advisors.
It will also provide links to international newspapers, a schedule of key technology events and on-line databases.
Richard Summers, director of continental Europe and technology at 3i says InsideEdge is the first known VC site of its kind.
“InsideEdge is a significant development for 3i and reinforces our position as a leading investor in technology businesses, that adds value to the companies in which it invests.”
