Spoke is an online network of over 35 million people. Membership to Spoke gives you the freedom to explore their database and connect with other professionals. 

Much like LinkedIn, Spoke offers both free and pay accounts, where you have to decide which is the best for your recruiting and sourcing needs. Pay accounts essentially get more search results and some easier information to work with and options for contacting people. The free account let’s you know the name of the contact, the company they work for and sometimes their number, if not the main number of their company for starters. No emails are provided, but a good sourcer should be able to figure out the email pattern from there.

Here is a search example below. I used Spoke to search for Software Engineer’s located in California. 6,259 results came up. Give it a try and let me know your thoughts.
