Why do sourcing professionals, Fortune 500 and Global 1000 companies join SIG? SIG is the original Executive Sourcing Network. Since 1991 the world’s top procurement, sourcing, outsourcing, shared services and global business services executives have turned to SIG to stay up-to-date with best practices and thought leadership from leading companies in our industry.

With a 92% retention rate, SIG members cite "amount of time and money saved with insight gained through SIG" as the primary reason for renewal. The strict no-selling environment allows SIG members to escape "exhibit hall craziness" and focus their attention on true benchmarking with peers. Membership combines an unprecedented 3:1 ratio of buy-side to sell-side companies.

SIG's membership program is designed to meet the unique needs of sourcing professionals and enterprise organizations who want to optimize the performance of their function and business. Our various membership levels provide specific benefits for every type of member we serve: buy-side and sell-side individuals, teams and companies. 


SIG membership gives you a competitive advantage and an opportunity to stay in front of evolving industry trends. We offer a variety of resources for our members, including:


Our members-only SIG Resource Center (SRC) includes more than 5,000 searchable documents, including research reports, templates, whitepapers and archived event presentations. This one-stop repository allows members to log in and search by topic, keyword, author and more.


Leverage SIG’s vast membership to benchmark and find solutions via our Peer2Peer program. Members can use the forum to locate resources, source providers, seek advice from the SIG community and share their lessons learned. The Peer2Peer program enables SIG members to share best practices on topics specific to their needs.
