1 – LinkedIn

LinkedIn is probably the biggest network that is dedicated to professional users. If you’re looking to make friends and start an online relationship then this isn’t really the site for you. However, if you’re looking for a new career, are setting up a new business, or want to find the best advice then this is a great site that will almost certainly deliver the results you want. The only slight problem with the site is that a paid membership is required for some of the more advanced (and often beneficial) features.

2 – E.Factor

E.Factor is geared towards budding and experienced entrepreneurs. It is more than a social networking website alone because it provides everything including a network of nearly a million users, a network of investors and angels, regular low price entrepreneur related events, and reduced rates on hotels, flights, and even car hire. A single membership can go a long way and while the membership list is slightly smaller than other similar sites it is definitely growing and one to watch out for.

3 – Cympitch

Cympitch is another social networking that combines numerous elements for entrepreneurs and this one is designed especially for the UK market. It is billed as being the social network for “connecting UK entrepreneurs and early stage investors” so is similar to E.Factor in its goals and its uses. You can also use the site to receive quotes and therefore give them, and seek the advice that many entrepreneurs need.
